Over the past 12 months, this article was one of the TOP TEN most-read Daily Bulletin features. We’re reprising it today for those who may have missed it the first time. The above diagram comes from a TiborasurasRex YouTube Video comparing G1 and G7 BC models. CLICK HERE to watch the video.
The better, up-to-date ballistics programs let you select either G1 or G7 Ballistic Coefficient (BC) values when calculating a trajectory. The ballistic coefficient (BC) of a body is a measure of its ability to overcome air resistance in flight. You’ve probably seen that G7 values are numerically lower than G1 values for the same bullet (typically). But that doesn’t mean you should select a G1 value simply because it is higher.
Some readers are not quite sure about the difference between G1 and G7 models. One forum member wrote us: “I went on the JBM Ballistics website to use the web-based Trajectory Calculator and when I got to the part that gives you a choice to choose between G1 and G7 BC, I was stumped. What determines how, or which one to use?”
The simple answer is the G1 value normally works better for shorter flat-based bullets, while the G7 value should work better for longer, boat-tailed bullets.
G1 vs. G7 Ballistic Coefficients — Which Is Right for You?
G1 and G7 refer both refer to aerodynamic drag models based on particular “standard projectile” shapes. The G1 shape looks like a flat-based bullet. The G7 shape is quite different, and better approximates the geometry of a modern long-range bullet. So, when choosing your drag model, G1 is preferrable for flat-based bullets, while G7 is ordinarily a “better fit” for longer, boat-tailed bullets.
Drag Models — G7 is better than G1 for Long-Range Bullets
Many ballistics programs still offer only the default G1 drag model. Bryan Litz, author of Applied Ballistics for Long Range Shooting, believes the G7 standard is preferrable for long-range, low-drag bullets: “Part of the reason there is so much ‘slop’ in advertised BCs is because they’re referenced to the G1 standard which is very speed sensitive. The G7 standard is more appropriate for long range bullets. Here’s the results of my testing on two low-drag, long-range boat-tail bullets, so you can see how the G1 and G7 Ballistic coefficients compare:
G1 BCs, averaged between 1500 fps and 3000 fps:
Berger 180 VLD: 0.659 lb/in²
JLK 180: 0.645 lb/in²
The reason the BC for the JLK is less is mostly because the meplat was significantly larger on the particular lot that I tested (0.075″ vs 0.059″; see attached drawings).
For bullets like these, it’s much better to use the G7 standard. The following BCs are referenced to the G7 standard, and are constant for all speeds.
Many modern ballistics programs, including the free online JBM Ballistics Program, are able to use BCs referenced to G7 standards. When available, these BCs are more appropriate for long range bullets, according to Bryan.
[Editor’s NOTE: BCs are normally reported simply as an 0.XXX number. The lb/in² tag applies to all BCs, but is commonly left off for simplicity.]

Ian Klemm, 2017 F-TR USA National Champion, is one of America’s top F-Class shooters, both shooting individually and in team competition. Ian is known for his consistency, smooth gun handling, and an uncanny ability to shoot well even in the toughest wind conditions. In this Vortex Video, Ian and fellow long-range shooter Niles Richardson, reveal some of their competitive secrets, and wind-reading techniques. This video focuses primarily on F-Class competition but Ian and Niles also talk more broadly about the myriad factors that contribute to rifle accuracy. Topics include: match strategies, wind and mirage reading, barrel harmonics, bipods, and optics.
Vortex Nation Podcast Episode 57 Summary
From Vortex: Our original intent was to have just a podcast about the sport of F-Class shooting, but when you get these brainiacs (Ian Klemm and Niles Richardson) talking about their obsession… er… “Hobby” you better believe it’s going to turn into a full on long range shooting information assault to the brain. Fact of the matter is, in F-Class, the only thing that matters is long range accuracy – and when we say “Accuracy”, we’re talking about sub-MOA groups on paper at 1000 yards with .308 Wins. Every single aspect of an F-Class competitor’s game is completely dialed in for long range accuracy.
We talk about the guns, their bipods, wind, mirage, barrel harmonics and the special scopes F-Class competitors need for their rifles. Ian even goes so far as to tell us how much his rifle has moved prior to the bullet leaving his 30-inch barrel. Just a simple equation involving acceleration, terminal velocity, moment of inertia of the rifle and coefficient of friction of the bipod and rifle on the ground.

Want to learn long-range benchrest skills from the best in the business? Then head to Williamsport, PA this June. The registration period for the 2019 PA 1000 Yard Benchrest School is now open. This year’s session will be held Saturday and Sunday, June 8-9, 2019, with a “Meet and Greet” on Friday night, June 7. Classes, taught by top 1K shooters, are held at the Original Pennsylvania 1000-Yard Benchrest Club Range, one of the best 1000-yard ranges in the country. The school will be limited to 24-30 students with one instructor for every two students.
Praise from a 1K Benchrest School Grad
Here’s a testimonial from a recent graduate: “I can attest to the knowledge that you gain. I went last year and loved it. Have renewed my membership in the Club and would love to go this year. I would love to take the course again. In the photo above I am in the back row, fourth from the right — sunglasses and blue shirt.” — Bob, Class of 2016
Participants will learn all aspects of long-range benchrest shooting from some of the most skilled marksmen in the country. Much time is spent at the loading bench and on the firing line. Classes cover load development, precision reloading, bench skills, and target analysis. You don’t even need guns and ammo — all equipment and ammunition will be provided.
School instructors tell us: “This year’s benchrest school will be a 2-day weekend event. (There is also an optional ‘Meet and Greet’ gathering Friday evening). The school is a beginner class designed to teach the fundamental skills needed to be competitive at at 600 and 1000 yards. Saturday will be spent in class covering a range of topics including reloading ‘dos and don’ts’, load development and equipment handling. Sunday we will shoot an actual match to see what you’ve learned.”
After taking this class, you might be the guy who shoots an amazing 100-8X at 1000 yards like this:
Cost for the class is $475.00 including lunches on Sat/Sun and dinner on Saturday. Act soon if you want to attend the 2019 school — the program fills quickly. The classroom is limited to only 24 (possibly 30) students and instruction is one instructor per two students. A one year membership is included with the cost of the school.

AccurateShooter.com offers dozens of FREE, printable targets for target practice, load development, and fun shooting. We also offer a few of the most popular NRA Bullseye targets. One or more of these printable targets should work for most training purposes. However, some readers have asked: “Where can we get the real targets… exactly like the ones used in NRA, IBS, and NBRSA shooting matches?”
All these vendors carry nearly all the NRA High Power and Smallbore targets, including the new, smaller F-Class targets. Germany’s Kruger Targets sells all the important NRA targets, and international (ISSF) air rifle and smallbore targets too.
Orrville Printing currently sells IBS targets for rimfire (50 yard) benchrest, short-range centerfire Benchrest (100, 200, 300 yards), Hunter BR Rifle (100, 200, 300 yards), plus the official 600-yard and 1000-yard IBS targets. National Target Company also has most of the IBS targets. NBRSA short-range, 600-yard, and 1000-yard benchrest targets are available directly from the NBRSA Business Office. Call (307) 655-7415 to order for the season.
At Western CMP Games, veteran rifle competitors Leon Rutherford, left, and Don Rutherford, demonstrate how to score targets at the GSM new shooter clinic. Note the use of a separate Target Center, which is available from many of the vendors listed above.

Many guys getting started in long range shooting are confused about what kind of scope they should buy — specifically whether it should have MIL-based clicks or MOA-based clicks. Before you can make that decision, you need to understand the terminology. This article, with a video by Bryan Litz, explains MILS and MOA so you can choose the right type of scope for your intended application.
You probably know that MOA stands for “Minute of Angle” (or more precisely “minute of arc”), but could you define the terms “Milrad” or “MIL”? In his latest video, Bryan Litz of Applied Ballitics explains MOA and MILs (short for “milliradians”). Bryan defines those terms and explains how they are used. One MOA is an angular measurement (1/60th of one degree) that subtends 1.047″ at 100 yards. One MIL (i.e. one milliradian) subtends 1/10th meter at 100 meters; that means that 0.1 Mil is one centimeter (1 cm) at 100 meters. Is one angular measurement system better than another? Not necessarily… Bryan explains that Mildot scopes may be handy for ranging, but scopes with MOA-based clicks work just fine for precision work at known distances. Also because one MOA is almost exactly one inch at 100 yards, the MOA system is convenient for expressing a rifle’s accuracy. By common parlance, a “half-MOA” rifle can shoot groups that are 1/2-inch (or smaller) at 100 yards.
What is a “Minute” of Angle?
When talking about angular degrees, a “minute” is simply 1/60th. So a “Minute of Angle” is simply 1/60th of one degree of a central angle, measured either up and down (for elevation) or side to side (for windage). At 100 yards, 1 MOA equals 1.047″ on the target. This is often rounded to one inch for simplicity. Say, for example, you click up 1 MOA (four clicks on a 1/4-MOA scope). That is roughly 1 inch at 100 yards, or roughly 4 inches at 400 yards, since the target area measured by an MOA subtension increases with the distance.
MIL vs. MOA for Target Ranging
MIL or MOA — which angular measuring system is better for target ranging (and hold-offs)? In a recent article on his PrecisionRifleBlog.com website, Cal Zant tackles that question. Analyzing the pros and cons of each, Zant concludes that both systems work well, provided you have compatible click values on your scope. Zant does note that a 1/4 MOA division is “slightly more precise” than 1/10th mil, but that’s really not a big deal: “Technically, 1/4 MOA clicks provide a little finer adjustments than 1/10 MIL. This difference is very slight… it only equates to 0.1″ difference in adjustments at 100 yards or 1″ at 1,000 yards[.]” Zant adds that, in practical terms, both 1/4-MOA clicks and 1/10th-MIL clicks work well in the field: “Most shooters agree that 1/4 MOA or 1/10 MIL are both right around that sweet spot.”

At the 2018 National Matches at Camp Perry this past summer, the Civilian Marksmanship Program (CMP) introduced a new series of Long Range events. Three days of long range rifle matches, held at 800, 900 and 1,000 yards, were added to the summer 2018 schedule to allow long range marksmen the opportunity to fire on the Camp Perry grounds following the NRA’s decision to move the NRA High Power Long Range Championship (and HP Championship) to Camp Atterbury, Indiana. Long Range matches will be held again at Camp Perry next year, from August 6-9, 2019 — put those dates on your calendar.

Competitors at the 2018 Long Range Matches at Camp Perry fired in Service, Match, and Palma rifle classes. Six matches were fired during the Long Range series. Those who participated in the inaugural LR matches were pleased that Long Range was featured again at Camp Perry after a two-year absence:
“Camp Perry is one of the best ranges in the U.S. with a long and proud history. Thank you, CMP, for all of the work expended on the 2018 season.”
“The matches were well-organized and went smoothly.”
“I liked the fact that they were held at Camp Perry. That’s where the National Matches should be.”
“Good job! I enjoyed the matches. It was great being back at Perry for long range.”
“Overall a very positive and fun championship for me. I applaud your efforts in bringing long range back to Camp Perry….”
Winning the overall Aggregate was USAMU shooter SFC Shane Barnhart with 1244-71X. Teammate SGT Lane Ichord won the service rifle division with 1228-48X, while Robert Steketee topped the Palma rifle class with 1233-56X. As the “top gun” for the match, SFC Barnhart was the first recipient of the Coats Brown Memorial Trophy – donated to the CMP by the Military Marksmanship Association. Chief Warrant Officer 4 Coats Brown, was a repeat National Matches champion and became the head coach of the newly-formed Army Marksmanship Unit in 1956.
John Whidden cleaned the Viale Memorial event with the match rifle, with a score of 200-12X. Robert Gill, 59, of Visalia, CA, led the Palma rifle portion. The Bataan Memorial 4-person Team Match, which included 20 shots by each member at 1,000 yards, saw wins from the AMU in both the match and service rifle categories. Members of AMU Green (SFC Barnhart, SFC Brandon Green, SGT Ben Cleland, and SSG Amanda Elsenboss), each dropped only one point in the match rifle class to record an Aggregate score of 796-54x.
Major Sponsors for Camp Perry Long Range Matches
Geissele Automatics served as a generous sponsor for the new Long Range events, donating a prize to every winner in each category. Capstone Precision, the parent company of Berger, Lapua, SK and Vihtavuori, also donated prizes to several winners during the National Long Range Matches.
SAVE THE DATE in 2019: The CMP’s Long Range Matches will take place August 6-9 at Camp Perry, in Port Clinton, Ohio. Events include three days of Individual Long Range Matches, two days of Team Matches, the Camp Perry Palma Match, Shooter’s Reception and Long Range Awards Ceremony.

The 2018 IBS 1000-Yard Nationals event was hosted by the Montana NW 1000 Yard BR Club, which has an active and well-run 1K benchrest shooting program. Over eighty shooters from as far away as Indonesia participated, 82 in Light Gun, and 85 in Heavy Gun. By all accounts it was a very well-run match, that was enjoyed by all who attended.
The Deep Creek Range is a beautiful place to shoot, with normally favorable conditions. But the winds were challenging at the 2018 IBS 1000-yard Nationals.
One man, Carroll Lance, dominated the match, taking the 2-Gun Overall Aggregate, while also winning HG Score Agg, HG Group Agg, and HG Overall Agg. It was a masterful performance — Carroll shot his Light Gun in both classes, beating dozens of bigger, heavier, and much more expensive rifles. Carroll’s name will be placed on four IBS perpetual trophies. Here’s Carroll with his line-up of trophies.
Winning Form — Carroll Lance Talks Technique
When asked for his advice to a new shooter, Big Winner Carroll Lance said: “Shooters should concentrate on being smooth, so as not to disturb the rifle in the bags. Speed will come naturally. The common mistake is to try to run the shots faster than can be done smoothly.”

Challenging Conditions at Match
While Deep Creek is renown for often having good, “readable” conditions, this was a tough year according to Deep Creek veterans. As proof, there were five DQs on a single relay.
Tom Mosul (who ran the firing line for most of the event) noted that conditions were not extreme but could be tricky, with max wind speed s10-15 mph. It varied enough that being on some relays could effectively put a competitor out of the tournament. Tom also mentioned that indicators that he normally could depend on were not reliable this year.
Leo Anderson, who has been present at nearly all the 1000-yard matches ever held at Deep Creek, said this 2018 match had some of the trickiest conditions he has seen in 20 years of competition. Leo said you could not see the conditions causing POI changes. Alex Wheeler agreed, and added that although it was pretty calm at the benches, that the scorer who was running targets (from the pits to the firing line) said there was a strong cross wind half way down range that could not be felt at the pits or firing line…typical for Deep Creek, tough to read when it does decide to be nasty.
Summary of IBS 1000-Yard Nationals Match Results
For those who are unfamiliar with long range benchrest results, there are seven categories of winners, with seven corresponding traveling trophies (the big ones that bear the names of each year’s winners). For each of the two rifle classes (Light Gun and Heavy Guun) there are group, score, and overall aggregate winners (every target is both measured for group size and scored.) Finally, there is a 2-Gun winner for both rifle classes combined, based on group AND score.
With over eighty competitors, the PDF of the complete results, including those of every relay plus a very detailed list of the equipment used by every competitor for both classes, is a whopping 52 pages long. Links Below:
Equipment List Light Gun and Heavy Gun Classes
The seven travelling trophies went to just three shooters. Cody Finch won the LG Group aggregate. Tim Gonnerman won the LG Score aggregate and LG Overall aggregate. Carroll Lance won everything else — HG Score aggregate, HG Group aggregate, HG Overall aggregate, and the 2-Gun Overall.
Big winner Carroll Lance shot his 6mm Dasher Light Gun for both classes. The rifle, smithed by Jay Cutright, features a Borden BRM drop port action, Krieger barrel, Wheeler LRB stock, and Nightforce scope. Carroll’s match-winning load consisted of Vapor Trail bullets, in front of H4895 powder and CCI primers.
Cody Finch’s Light Gun was a 6BR Ackley (6BRA) with Lederer barrel, BAT action, Nightforce scope, and a DCT stock. His load consisted of Vapor Trail bullets, Hodgdon powder, and CCI primers. Alex Wheeler smithed the rifle.
Tim Gonnerman’s Light Gun, smithed by Mike Bigelow, featured a Krieger barrel (6mm Dasher), BAT action, Nightforce scope, and McMillan stock. The load consists of Vapor Trail bullets, H4895 powder, and CCI 450 primers.
Equipment List by Class Based on Two-Gun Overall Agg Rankings Light Gun Equipment List (click to zoom):
I called the major Aggregate winners (Carroll Lance, Cody Finch, and Tim Gonnerman), and asked them about the 1K Nationals. My questions fell into five major categories: 1) how the wind compared to other matches (including other locations); 2) how each handles his rifle and equipment; 3) how they shot the match; 4) how they clean their barrels (and what their barrel accuracy life is); and 5) How they reload.
They all described the conditions as challenging. This was not a match to use for spotting small differences in accuracy between similar calibers. Even with the rotations of relays and benches, there was an inescapable luck factor, with some relays having significantly more challenging conditions than others. Changes could be rapid, with reversals that could be extreme.
Gun-Handling: On the subject of how the rifle is handled, Cody Finch shoots with only trigger contact, while Tim Gonnerman and Carroll Lance have light stock contact. Tim said that he is so focused on shooting that he is really not aware of the details of how he handles the rifle. Carroll said that he makes light contact with his trigger hand and has the butt touching his shoulder so lightly that he can barely feel it, but solidly enough that it only recoils about a quarter inch.
Shooting Strategies: Cody uses his sighter period to investigate how differences in mirage affect bullet impact location and then holds off shot by shot during his record string. Tim and Carroll do not, they adjust their scopes using the last sighter shot (which they can see because there is target service like an high power match with spotter disks) and then hold center for their record, trying to do as little with their rest adjustments as possible. Carroll mentioned that he only made one adjustment for the whole weekend and that his usual practice is to make small corrections with hand pressure.
Barrel Cleaning: Tim shot the whole weekend, without cleaning. When he does clean he uses Pro Shot Copper Solvent, patches, a nylon brush, and does a lot of soaking. Periodically he uses IOSSO with a patch on a nylon brush. He breaks in his barrels with the common one-shot-and-clean progressing to three and then five, and, sees a velocity increase at about 120 rounds from new. Tim cleans with patches and bronze brushes. I smiled when he told me what he cleans with, CLR, ThorroClean (Bullet Central) and IOSSO. CLR has been the topic of some discussion on the internet, and a friend found that it did a good job on carbon. It has been a controversial topic. Of note, Tim shot the smallest group for the tournament.
Barrel Life: All three Top Guns said that accurate barrel life varied from barrel to barrel. I got the general impression that most were done or close to done by 1,500 rounds, at least for the Dasher, with the BRA being too new to tell if it would stretch that far, but that it might.
Reloading Methods: On the reloading side, none of them anneal regularly, if at all. Carroll’s cases had 15-20 firings on them, and had only been annealed once, early on, but they still felt good when he was seating bullets. Last year he tried to anneal after every event.
Most of his competition has been at 600 yards, where Varget did a good job, with bullets seated .010 to .012 into the lands, but it did not perform well at 1K so he switched to H4895, which likes its bullets .005 into the lands. The chamber has a .268 neck. Case necks were turned to .0105 for a loaded round clearance of about .003. He used a .263 bushing.
Starting with a fired case, he sizes in a FL bushing die, tumbles in corn cob media to remove the lube, and just before seating bullets applies graphite to the insides of case necks with a Q-Tip.
Course of Fire at 1K Nationals (as explained by Tom Mosul):
“Relays were rotated along with bench assignment within each relay. The match is a three-target Aggregate, so what we did was divide the total number of relays and benches by 3, and then rounded down. Due to the number of benches (13) and shooters there were seven relays per target. Saturday morning started with LG target #1, followed by HG target #1, finishing the day with LG target #2. Sunday morning began with HG target #2, then LG target #3, and finished with HG target #3. For each relay six minutes are allowed for sighter shots, followed by a cease fire, and within a minute after that, a ten-minute record period.”
True Treasure Trove of Prizes at Deep Creek
There was a very rich prize table, including BAT, Borden, Curtis Custom, and Defiance actions; McMillan, McMillan/Wheeler and Shehane stocks; Kahles, Nightforce, Swarovski, and Vortex Scopes; SEB NEO Rest; Benchsource Annealing machine; Bartlein, Brux, Lilja, Krieger, and Rock Creek barrels; Zeiss Binoculars; many gift certificates (incl. Kelbly’s and McMillan) and much more.
The Top Guns got the pick of the prizes. Carroll Lance chose a Kahles 10-50 rifle scope, Tim Gonnerman chose a BAT Neuvo action, and Cody Finch chose a Borden BRM action.
NOTE: Prizes that manufacturers and vendors contribute are an important part of any successful match. I am sure that everyone who was connected with this event is grateful to all the generous sponsors who donated prizes and gift certificates. Sebastian Lambang (shown below), creator of SEB Rests, shot the match and donated a SEB NEO rest.

Our friend Kevin Nevius, best known for his smallbore skills, went head to head against the nation’s top long-range aces this past week, and emerged on top. Besting the likes of past multi-time Long Range Champions David Tubb and John Whidden, Kevin Nevius shot superbly at Camp Atterbury to win his first NRA National Long Range Championship. Kevin finished with 1245-64X, one point ahead of Phillip Crowe, 1244-74X. Bob Gill, shooting a .223 Rem with iron sights, was third on X-Count, with 1244-68X. Kevin built his own rifles for the match, using Kelbly centerfire actions in a Grunig & Elmiger smallbore stock. Here is Kevin’s first-hand report of his 2018 LR Championship victory.
2018 NRA Long Range Championship — Rising to the Challenge
by Kevin Nevius This was my first opportunity to shoot the NRA Long Range Nationals since its relocation to Camp Atterbury, and it was great to see everyone and get back to the matches. It is always so humbling walking onto the range and seeing all of the people I read about and admire so much. I can’t think of another sport where people so accomplished will share so much and be so helpful.
Regarding the weather, we had generally great conditions with very mild winds in the mornings, building gradually as the days progressed. By the afternoon hours, there were certainly challenges as the air started moving. Obstructions to the wind on either side of this range vary, so you needed to pay attention for sure — it may be calm at the targets or firing line, only to show something to worry about on the mid-range flags. Mirage is my primary indicator shooting smallbore, but mirage over 5/8ths of a mile is a little less telling (and a lot more confusing, at least for me!). I think most competitors, including me, use some combination of mirage and flags to make corrections. At the start of the string, I try to gauge a predominant condition, and more importantly which indicator is the most reliable to look at to determine that condition.
Smallbore shooting is where I learned to build a good position, and so much of that carries forward to Long Range High Power. It was a huge shock though, the first time I looked at a 44” aiming black through aperture sights at 1000 yards! Smallbore aiming blacks are twice as big, at one tenth the distance — the fact that we can hit something at 1000 yards with that sight picture still amazes me!
Kevin’s Arsenal — 6.5×47 Lapua and .308 Win Barreled Actions in Smallbore Stock
I have always build my own rifles, and always struggled to get the individual rifles you need for the LR aggregate (Any and Palma) and smallbore to feel, balance and fit identically. This year for the first time, I machined bedding blocks that allowed me to put almost identical centefire barreled actions into my smallbore prone stock – effectively making the position and fit of all the rifles for all disciplines identical (it is, after all the same stock used for everything).
I used two modified Kelbly Grizzly actions (one barreled in 6.5×47 for the any rifle matches, and one barreled in 308 for Palma) fitted to two identical aluminum bedding blocks. The bedding block footprint matches my smallbore barreled action – a Grunig & Elmiger Racer WC. The stock is a Grunig & Elmiger Hybrid, which is a composite aluminum skeleton and carbon fiber skin.
Championship-Winning 6.5×47 Lapua and .308 Win Loads
I was using a 6.5×47 Lapua in the “Any Rifle” matches. The barrel is a 1:8″-twist Benchmark medium Palma contour finished at 35 inches, throated +0.060″. My 6.5×47 load was Lapua brass, CCI 450 primers, VV N160 powder, and 140 grain Berger Hybrid bullets. For the Palma match, a .308 Win barreled action was fitted in the same Grunig & Elmiger smallbore stock. The .308 barrel was another Benchmark 35″ medium Palma, using the current Fullbore chamber throated +0.120″. I was using Lapua .308 Palma small primer brass, Federal 205M primers, VV N140, and 155 grain Lapua Scenar L bullets.
Shooting Between Champions — Tubb on the Left, Whidden on the Right
On the final day (the Palma Individual), we were squadded based on seed position, so David Tubb was on my left, and John Whidden on my right. I am not sure if a more intimidating position on the firing line exists, but it was so clear to me especially on that last day how blessed I was to be there. In every match, there is an element of luck — regarding weather, squadding assignment, target service, firing point condition, even equipment malfunction. A host of things can go wrong…
I lost my very first shot at 900 mostly due to elevation (I was coming a little unhinged with the realization I might be in the lead – just being completely honest!), and settled down to clean the remainder of the string. The wind had built by then, and would run both right and left with the small boils in between. At 1000 I lost two, and was pretty happy with that. It was getting pretty dicey, and I resigned myself to the fact that it was becoming one of those days where 10s were enough (and Xs were pure luxury!). John shot well at 1000, but he always does — I don’t think there is a better long range shooter in the country and it’s been that way for a bunch of years. I can’t say enough about him – he is a dear friend and everything a champion should be. (Editor: Whidden finished fourth overall, at 1243-78X, with high X-count for the event.)
To put it all together takes so many things — preparation, tuning, load development, position practice. And yes, it takes some divine intervention for sure. I will never forget this experience, and am so grateful to have been successful this year.
John Whidden of Whidden Gunworks congratulated Kevin: “I was really proud of my friend Kevin Nevius and his fine shooting over the match. Kevin is respected both for his shooting and his character. The match went well and a number of improvements were made over last year. The targets were better, the number boards better, and the match ran very efficiently. Kudos to those who made these positive changes happen.”
Tough Time for Tubb on Last Day
Kevin noted that it was intimidating to be squadded between David Tubb and John Whidden, two multi-time Champions. Unfortunately Tubb, who had shot brilliantly (800-50X) throughout the Long Range event, had issues with his .308 Palma rifle on the final day. Kevin noted: “Yes David had some problems with his .308. When we arrived at the range on the last day, for the Palma Individual, David was in the lead with 800-50X, having shot ‘clean’ (not dropping a point). Bob Gill was second with 798-43X, and I was in third place with 798-42X. As we started the 800-yard string, there was some commotion going on to my left, and all I know is that as we finished and started moving to 900 yards, David was not happy. I believe he had lost 4 points at 800. We went to the pits, and he said his rifle was not shooting well, and he was pretty unhappy to say the least. He tried to adjust the seating depth of his ammunition before heading back out to the 900-yard line, in the hopes the gun would shoot better”. But it ended up a very tough day for David, as his chances for another LR Championship vanished.
Editor: With a 800-50X total, David Tubb was the Winner of the Canadian Cup Trophy, earned before the last day.
Bob Gill Proves the .223 Remington (and Iron Sights) Can Be Competitive
There were many interesting stories at this year’s Long Range Championship. The .223 Rem Eliseo Tubegun belonging to Californian Bob Gill proved to be “the little rifle that could”. Gill shot his .223 Rem Palma rifle for the entire Long Range Championship cycle. And yes Bob shot irons the whole way, even during the Remington and Wimbledon “Any Sight” matches where scopes are allowed. Kevin observed: “Bob Gill was amazing, and that rifle must be pretty awesome too. I don’t think I have ever seen someone shoot a .223 Rem at 1000 yards that well — ever. I believe Bob was shooting 80 grain bullets. As I pulled for Gill on the third day, I can testify that his bullets were still plenty supersonic!”
Editor: Gill finished 3rd overall, just one point down from Kevin, and six Xs behind runner-up Phillip Crowe. Gill also won the Sierra Trophy.
Our friend Anette Wachter (aka 30CalGal) is profiled this month on the NRA Family website. Annette talks about how she got into the shooting sports (though a challenge from her ex-husband), and how she has advanced along the way. She is now one of the top female Palma shooters in the nation. She also now competes regularly in Precision Rifle matches — tactical style competitions. She enjoys the challenge of PRS events, and she also competes in 3-Gun matches, with pistol, rifle, and shotgun.
Anette writes about the shooting sports for many publications. She also offers tips and gear reviews through her popular website, 30CalGal.com.
NRA: What type of shooting do you do, and what makes you like it so much?
Anette: Mostly long-range rifle disciplines. I don’t shoot High Power much anymore, but of course I am on the U.S. National Rifle Team and the Palma Team, so that occupies much of my time. My new love is Precision Rifle. This is the new hot and trendy shooting sport that is taking over the industry. It is like a sniper challenge. All unknown distances and usually the matches are out in the field. I also compete in 3-Gun, which is a ton of fun.
NRA: What advice do you have for new shooters who want to get into these sports?
Anette: If you want to get in to any discipline of competition I always suggest going to a local match to watch first. With the Internet you can find out your state competition information. Look for local organizations like the USPSA. See the type of equipment shooters are using and how the sport is run. Ask a lot of questions. Shooters are a very generous culture as well, in my experience. When I started out I was loaned almost everything to try it out.
NRA: From what you have seen, are there a lot more women getting involved in the shooting sports these days?
Anette: I started shooting and competing in 2006. I remember going to NRA Nationals at Camp Perry and, out of almost a thousand competitors, I was one of maybe 20 to 30 women. At local matches I would be one of two. In the past five or six years and especially in the last three, I have seen the numbers jump like crazy. Three years ago a few women in the 3-Gun market decided to put on the first Ladies 3-Gun ProAm in Georgia. We were wondering if anyone would show up. Over 200 women competed. Any of us that had extra guns and equipment were loaning them out. For many of the women it was their first match ever. It changed lives.

Shown above is David Tubb, the legendary 11-time National High Power Champion, posing with a very serious rifle used in the Extreme Long Range (ELR) game. David has jumped into the Extreme Long Range discipline in a very big way, producing a .375-caliber, long-barreled ELR version of his famous Tubb rifle, called the Adaptive Target Rifle (ATR). A version of this rifle, piloted by David’s son-in-law Nate Stallter, set the current ELR World Record in January 2018. See video below for a full report.
This video shows Team TUBB setting a new ELR World Record of 2011 Yards using the Tubb Adaptive Target Rifle in .375 CheyTac. Nate Stallter nailed three shots at over one mile — 1768 yards. Then Nate broke his own record, going 3 for 3 at 2011 yards. ELR Central hosted this match, held at the Front Sight gun range, Pahrump, NV on January 21, 2018.
David Tubb will Be Working with Chase Stroud
David has been working with Chase Stroud, a talented young Texan who has competed in tactical rifle competitions and worked with Team Applied Ballistics on ELR projects. Chase has long respected Tubb’s shooting ability as well as his design/engineering talent in developing successful rifle platforms, such as the ground-breaking Tubb 2000.
Recently, Chase had the opportunity to shoot long range with David Tubb. David crafted a left-hand ATR rifle for Chase who will be working with David in the future. Posting on Facebook, Stroud wrote:
“Growing up as a kid I taught myself to shoot long distance from David’s videos. David Tubb was my idol then and still is now. Never in my wildest dreams did I think I would share the line with him much less get to represent his product in the long range community. A literal dream come true for me….
Yesterday we shot some video for the new Tubb ATR system. After pressing him for years he made me a [left-hand ATR] and it shot unreal using his absolute ammo. I thank you … David. It’s time to get some practice under my belt and start shooting again…”

How would you like to represent the United States in top-level International Shooting competitions? Well, if F-Class is your game, here is your opportunity. F-Class Team USA will be conducting try-outs for the United States squads who will represent our country in F-TR and F-Open divisions (plus Under-25) at the 2021 World Championships. The try-outs are open to any competitive shooter with a class-compliant rifle and the will to win. Team leadership expressly welcomes newcomers.
Initial and primary tryouts are planned during the 2018 U.S. National Championships in Raton, NM, and the 2019 SW Nationals in Phoenix, AZ. There may also be an early 2019 tryout date at Butner, NC.
Dan Bramley Invites Shooters to Team USA F-Class Try-Outs
Official Invitation to Team USA F-Class Try-Outs To the F-Class Community–
On behalf of Team USA 2021, we are pleased to invite the best of USA F-class to consider joining our effort for the 2021 World Championships in Bloemfontein, South Africa. We are reaching out with this invitation to provide some general information on our plans for 2021 and for upcoming try-out dates for the unified Team USA: F-TR, F-Open, and Under 25.
We are moving forward with F-Open, F-TR, and Under 25 unified as one USA F-class 2021 Team. This will allow us to take advantage of each team’s strengths and provide needed purchasing power and coordination for event and logistic costs. We also believe this will help encourage and grow our sport. We will share ideas, event/facility dates and best practices within this unified team, however, individual team segments will make their own decisions. Therefore, please direct your responses and inquiries to the appropriate team leadership.
Being part of Team USA is a major commitment of time and resources. We do have wonderful and sizable sponsorship partners who we thank and rely on for moderating individual team member costs. However, due to the location of this World Championship effort, one can expect to help cover a commensurate level of the costs.
We are now moving into the USA “development team” stage of the process. This team is open to newcomers… there are many newer names showing up on the top of leader-boards and many new teams that are making positive impacts. If you are interested in being part of Team USA, please consider making that commitment. We would like to hear from you by March 23, 2018.
Team Time Expectations
Attendance at SWN and US Nationals will be expected for 2019 and 2020. We will also likely expect the final team to attend the Berger SWN in 2021 or have an alternative site for a final practice prior to our trip. We will try to have afternoon or evening team sessions during these events however we may have team days just prior or after these events to maximize the use of individual travel dollars and time. We will also likely have additional team training dates in 2019 and 2020, likely on east coast ranges to facilitate best availability for all.
Shooting/Coaching Position Opportunities
We are equally passionate about developing coaching/shooting teams for winning gold medal efforts in both the Richardson Cup (8-man) and Rutland Cup (4-man) World Championship Events. Obtaining a shooting or coaching spot on one of these teams is an absolute gauntlet of a commitment and consistent strong results will be required as the USA is blessed with wonderful depth. We encourage all, with proven success in our sport, to test themselves at this highest of levels.
Team Try-Out Dates and Locations
Initial and primary tryouts are planned during the 2018 US National Championships in Raton, NM and the 2019 SW Nationals in Phoenix, AZ. There may also be an early 2019 tryout date at Butner, NC.

With the Berger Southwest Nationals underway this week, we thought we’d steer our readers to a very useful resource, courtesy Berger Bullets. This online Stability Calculator helps shooters determine the optimal twist rate for their choice of projectiles.
Berger Twist-Rate Stability Calculator
On the Berger Bullets website you’ll find a handy Twist-Rate Stability Calculator that predicts your gyroscopic stability factor (SG) based on mulitiple variables: velocity, bullet length, bullet weight, barrel twist rate, ambient temperature, and altitude. This cool tool tells you if your chosen bullet will really stabilize in your barrel.
How to Use Berger’s Twist Rate Calculator
Using the Twist Rate Calculator is simple. Just enter the bullet DIAMETER (e.g. .264), bullet WEIGHT (in grains), and bullet overall LENGTH (in inches). On its website, Berger conveniently provides this info for all its bullet types. For other brands, we suggest you weigh three examples of your chosen bullet, and also measure the length on three samples. Then use the average weight and length of the three. To calculate bullet stability, simply enter your bullet data (along with observed Muzzle Velocity, outside Temperature, and Altitude) and click “Calculate SG”. Try different twist rate numbers (and recalculate) until you get an SG value of 1.4 (or higher).
Gyroscopic Stability (SG) and Twist Rate
Berger’s Twist Rate Calculator provides a predicted stability value called “SG” (for “Gyroscopic Stability”). This indicates the Gyroscopic Stability applied to the bullet by spin. This number is derived from the basic equation: SG = (rigidity of the spinning mass)/(overturning aerodynamic torque).
If you have an SG under 1.0, your bullet is predicted not to stabilize. If you have between 1.0 and 1.1 SG, your bullet may or may not stabilize. If you have an SG greater than 1.1, your bullet should stabilize under optimal conditions, but stabilization might not be adequate when temperature, altitude, or other variables are less-than-optimal. That’s why Berger normally recommends at least 1.5 SG to get out of the “Marginal Stability” zone.
In his book Applied Ballistics For Long-Range Shooting, Bryan Litz (Berger Ballistician) recommends at least a 1.4 SG rating when selecting a barrel twist for a particular bullet. This gives you a safety margin for shooting under various conditions, such as higher or lower altitudes or temperatures.
Story idea from EdLongrange. We welcome reader submissions.

The better, up-to-date ballistics programs let you select either G1 or G7 Ballistic Coefficient (BC) values when calculating a trajectory. The ballistic coefficient (BC) of a body is a measure of its ability to overcome air resistance in flight. You’ve probably seen that G7 values are numerically lower than G1 values for the same bullet (typically). But that doesn’t mean you should select a G1 value simply because it is higher.
Drag Models — G7 is better than G1 for Long-Range Bullets
Want to learn long-range benchrest skills from the best in the business? Then head to Williamsport, PA this June. The registration period for the 2019 PA 1000 Yard Benchrest School is now open. This year’s session will be held Saturday and Sunday, June 8-9, 2019, with a “Meet and Greet” on Friday night, June 7. Classes, taught by top 1K shooters, are held at the Original Pennsylvania 1000-Yard Benchrest Club Range, one of the best 1000-yard ranges in the country. The school will be limited to 24-30 students with one instructor for every two students.
This was my first opportunity to shoot the NRA Long Range Nationals since its relocation to Camp Atterbury, and it was great to see everyone and get back to the matches. It is always so humbling walking onto the range and seeing all of the people I read about and admire so much. I can’t think of another sport where people so accomplished will share so much and be so helpful.
Being part of Team USA is a major commitment of time and resources. We do have wonderful and sizable sponsorship partners who we thank and rely on for moderating individual team member costs. However, due to the location of this World Championship effort, one can expect to help cover a commensurate level of the costs.
