We’ve all seen them — you know those guys who don’t follow range rules, or who handle firearms in a careless manner. Sometimes bad range etiquette is simply annoying. Other times poor gun-handling practices can be downright dangerous. The NRA Blog has published a useful article about range safety and “range etiquette”. While these tips were formulated with indoor ranges in mind, most of the points apply equally well to outdoor ranges. You may want to print out this article to provide to novice shooters at your local range or club.
8 Tips for Gun Range Etiquette
Story by Kyle Jillson for NRABlog
Here are eight tips on range etiquette to keep yourself and others safe while enjoying your day out [at the range]. Special thanks to NRA Headquarters Range General Manager Michael Johns who assisted with this article.
1. Follow the Three Fundamental Rules for Safe Gun Handling
ALWAYS keep the gun pointed in a safe direction.
ALWAYS keep your finger off the trigger until ready to shoot.
ALWAYS keep the gun unloaded until ready to use.
2. Bring Safety Gear (Eye and Ear Protection)
Eye and Ear protection are MANDATORY for proper safety and health, no matter if “required” by range rules or not. It is the shooter’s responsibility to ensure proper protection is secured and used prior to entering/using any range. Hearing loss can be instantaneous and permanent in some cases. Eyesight can be ruined in an instant with a catastrophic firearm failure.
3. Carry a Gun Bag or Case
Common courtesy and general good behavior dictates that you bring all firearms to a range unloaded and cased and/or covered. No range staff appreciates a stranger walking into a range with a “naked” firearm whose loaded/unloaded condition is not known. You can buy a long gun sock or pistol case for less than $10.
4. Know Your Range’s Rules
Review and understand any and all “range specific” rules/requirements/expectations set forth by your range. What’s the range’s maximum rate of fire? Are you allowed to collect your brass? Are you required to take a test before you can shoot? Don’t be afraid to ask the staff questions or tell them it’s your first time. They’re there to help.
5. Follow ALL Range Officer instructions
ROs are the first and final authority on any range and their decisions are generally final. Arguing/debating with a Range Officer is both in poor taste and may just get you thrown out depending on circumstances.
6. Don’t Bother Others or Touch Their Guns
Respect other shooters’ privacy unless a safety issue arises. Do NOT engage other shooters to correct a perceived safety violation unless absolutely necessary – inform the RO instead. Shooters have the right and responsibility to call for a cease fire should a SERIOUS safety event occur. Handling/touching another shooter’s firearm without their permission is a major breech of protocol. Offering unsolicited “training” or other instructional suggestions to other shooters is also impolite.
7. Know What To Do During a Cease Fire
IMMEDIATELY set down your firearm, pointed downrange, and STEP AWAY from the shooting booth (or bench). The Range Officer(s) on duty will give instructions from that point and/or secure all firearms prior to going downrange if needed. ROs do not want shooters trying to “secure/unload” their firearms in a cease fire situation, possibly in a stressful event; they want the shooters separated from their guns instantly so that they can then control the situation as they see fit.
8. Clean Up After Yourself
Remember to take down your old targets, police your shooting booth, throw away your trash, and return any equipment/chairs, etc. Other people use the range too; no one wants to walk up to a dirty lane.

The NRA’s Shooting Sports USA has a “new and improved” website. The new mobile-friendly format makes it easy to access current articles as well as locate interesting archived stories.
One great recent Shooting Sports USA article, Shooting is 90% Mental, was penned by Chip Lohman (SSUSA’s former Editor). With the help of two very smart Ph.D types, Judy Tant and Mike Keyes, Lohman examines the mental processes involved in the shooting sports. Chip’s co-authors have impressive credentials. Dr. Judy Tant is a Clinical Psychologist and National Bullseye Pistol Champion. Dr. Michael J. Keyes, is a licensed Psychiatrist and former physician for the U.S. Shooting Team.
If you shoot competitively, this is definitely a “must-read” article. The authors examine how the brain functions under stress, how “visualization” can be used to improved performance, how “brain speed” can be enhanced through proper training, and how the brain stores learned routines into “muscle memory.” And that’s just for starters — the article gives many concrete examples of techniques top shooters have employed to improve their “mental game” and shoot higher scores.
Brain Speed and Trigger Control:
Research: Scientists believe that the newer frontal lobe may not be able to keep up with “deep” brain signals that transmit at nearly 300 mph. This is explained when athletes talk about “letting go,” rather than over-thinking the shot. This conscious signal can take up to 0.3 seconds from recognizing the desired sight picture to moving the trigger finger—too long to capture the opportunity for a perfect shot. However, if the signal is initiated spontaneously in the cerebellum where such procedures are thought to be stored through repetition, the reaction speed is much quicker. Signals are processed by the “deep brain” almost twice as fast as the problem-solving frontal lobes.

More guns… more guns than ever. That’s what U.S. gun-makers have been cranking out. According to the latest BATFE Fireams Commerce Report, American gun manufacturers produced over ten million guns in 2013, the last full reporting period. That’s an all-time record.
The 2013 total of 10.885 million guns produced in 2013 represents a 27% increase over the 8.579 million guns made in 2012. What’s even more surprising, the 2013 total is nearly double the quantity product just three years before in 2010 — 5.459 million firearms. Any way you look at it, that’s a huge increase in firearms production in a very short time.
As a category, pistols (primarily semi-auto, and not counting revolvers) have seen the largest increase in production, rising from 662,973 in 1986 to 4,441,726 in 2013. Notably the number of wheelguns produced has actually declined from 761,414 in 1986 to 725,282 in 2013.
In recent years there has been a significant growth in the number of shotguns sold, due to increased consumer interest in scatterguns for sport and defense. The number of shotguns sold topped did break the million mark in 2013, rising from 949,010 in 2012 to 1.203 million in 2013, and increase of 27%.
There has also been a significant growth in NFA items sold over the last dozen years, lead by a huge increase in the number of suppressors. In fact, as we reported last week, from 2014 to 2015, the number of NFA-registered suppressors rose from 571,150 to 792,282. That’s a 39% increase in just one year! There are now nearly 800,000 suppressors now registered in the USA.
Sniper’s Hide has just released an interesting comparison test, running the $1150* Ruger Precision Rifle vs. a $7000 Accuracy International AX in a 450-yard “mad minute” drill. The goal was to see how many shots could be put on a 12″ steel target in one minute. Both rifles were chambered for the 6.5 Creedmoor and were fed with Hornady 140gr Amax ammo. The much cheaper Ruger did surprisingly well, though the AI AX did come out on top. Frank Galli, Head Honcho of Sniper’s Hide, got 19 rounds on target in one minute with the AI AX compared to 14 rounds with the Ruger.
Watch the “mad minute” face-off in this video:
Galli notes: “The target is 450 yards away, and, as noted in the video, we have winds gusting anywhere from 10 to 18 mph out on the Front Range of Colorado today. So my job is to not only hit the target as fast as possible, but to also manage the conditions.”
Frank Galli says the Ruger offers a lot of bang for the buck:
“For those looking to get into competitive tactical shooting, like a PRS Event, there is absolutely no excuse. This rifle will allow you to be competitive, the only thing that would hold a person back is themselves. The more this rifle is shot, the more impressive it is. Would I trade my Accuracy International for one? Well, odd question, but no. However for those on a budget I would recommend the Ruger in a heartbeat.”
*MSRP for the Ruger Precision Rifle is $1399.00. Some dealers are posting prices as low as $1100.00, but $1150.00 seems typical.

Deep Creek 1000-yard line: 46°55’35.03” N 114°14’45.40” W, elevation 3355′.
The International Benchrest Shooters (IBS) welcomes the Montana NW 1000 Yard Benchrest Club as a newly-affiliated club hosting registered IBS matches. The Montana club’s origins go back to 1996 when the Whitefish (Montana) Rifle and Pistol Club affiliated with the Original Pennsylvania 1000-Yard Benchrest Club (Williamsport) to conduct 1000-yard matches. Early in 1998 the Northwest 1000-Yard Benchrest Association was formed to promote 1000-yard benchrest competition in affiliation with Williamsport. The Club now operates at the Deep Creek Range as the Montana NW 1000 Yard Benchrest Club (www.MT1000yd.com), an IBS-affilated organization.
2015 Championships at Deep Creek
The 2015 Championships were held this past weekend, August 7-9. The video below features the winners from this year’s championships, Tom Mousel (Two-Gun Overall), Leo Anderson (Heavy Gun Overall), and Bill Johnson (Light Gun Overall). The three winners describe their equipment. Tom shot a pair of 17-lb 6mm Dashers, running Vapor Trail Bullets pushed by CCI 400 primers and Hodgdon H4895 powder. The brass is Lapua 6mmBR hydro-formed to Dasher with lightly-turned necks.
Here is one of Tom Mousel’s match-winning rifles, and an impressive 100-3X, 10-shot target:
The Club holds 12 shoots per year over six weekends that count towards the 6- and 10-shot Aggregates for the year. The Championship Shoot held in August is match number 11 and 12 and does not count for Aggs. More than $20,000 worth of prizes were donated by major sponsors this year. The prize table featured scopes from Nightforce and Vortex, actions from DeFrance, Borden, BAT, Kelbly, and Stiller, plus barrels from Bartlein, Benchmark, Brux, Caliber, Krieger, and McGowen.
The Deep Creek Rifle Range is located near Missoula, Montana. Club members are continually upgrading the 1000-Yard Range, which has become one of the best long-distance benchrest shooting facilities in the country. The Deep Creek Rifle Range invites shooters to visit this scenic shooting facility. Participation in club matches continues to grow, and club members hold several 1000-yard World Records for group, score, and Aggregates of both. For more information on club shoots and joining the club, contact Alex Wheeler: zfast_malibu [at] yahoo.com.
Here’s “Bunker Buster”, a metal-stocked Heavy Gun (HG):
At Deep Creek, competitors shoot three (3) classes: IBS Light Gun (LG), IBS Heavy Gun (HG), and a special 11-pound class. At registered matches, Light Gun shoots five shots per relay, Heavy Gun shoots 10 shots, while the 11-pound class shoots five shots. For more information on classes and courses of fire, visit MT1000yd.com or send email to: northwest1000ydbenchrest [at] gmail.com.
New World Records Set at July 2015 Match:
Important 1K records were set at the Club’s July 9-10 match earlier this summer. Tom Mousel broke the Light Gun 10-match score record and Heavy Gun 10-match group record. Jim Williams broke the HG 10-match score Agg record. In the video below, Tom Mousel talks about his record-breaking performances.

Tricked-out match guns are fun but, if you want to prove that you’ve got an eagle eye and steady hands, a true test of skill is the Civilian Marksmanship Program’s As-Issued Four Gun Aggregate.
The Four Gun Aggregate encompasses a series of CMP John C. Garand 30-shot matches (200-yard As-Issued Military Rifle Match Course A) on NRA SR targets at one of the CMP Regional Games or the Nationals officiated by the CMP. These are the only places you can earn the coveted neck-ribbon CMP achievement medals.
You will need four as-issued rifles. The first is the M-1 Garand. (The course of fire is named after this rifle’s inventor.) This remarkable battle rifle will test your prowess at slow prone, rapid prone, and offhand. The match winner will put almost all bullets into a saucer.
You do get to hear that classic “ping” when the en bloc clip ejects with this gun. It’s a good idea to write your firing point number on your hand for each match because you will move around over the course of the tournament.
Next comes the hyper-accurate 1903 Springfield. You can use either the WW I M1903 or the later WW II M1903A3 model with peep sights. A Springfield will typically shoot groups half the size of a Garand with the same ammunition. Think potential in terms of tea cups instead of saucers.
Initially drawn to the 6mmBR and 6mm Dasher, I realized these cartridges wouldn’t feed from an AICS magazine system without extensive modification. I took a look at the 6mm Creedmoor, 6XC, and 6mm-6.5×47 Lapua (aka 6×47 Lapua), all of which feed well from a detachable magazine. At right you can see the 6×47 Lapua in an AICS magazine. It has the “Goldilocks factor” — not too long, not too short.
The ability to simply convert 6.5×47 Lapua brass to 6×47 brass by running the parent 6.5mm brass through a full-length Forster sizing die in a single step was what made me choose the 6×47 Lapua over the 6mm Creedmoor and 6XC (both excellent cartridges in their own right). I also own a 6.5×47 Lapua rifle, so I had a supply of 6.5×47 brass ready to neck-down. Being able to create 6×47 brass easily (one pass and done) was very appealing.
Left to right, below: 6mmBR, 6-6.5×47 Lapua, 6.5×47 Lapua, and .243 Winchester.
I cut the chamber end off my .243 Win barrel, threaded and chambered my rifle for the 6×47 Lapua cartridge. I have written a lengthy article on this cutting and re-chambering process. Home gunsmiths interested in this process can READ MORE HERE.
When the re-chambering was complete, I headed to the range and worked up a set of eight loads using Berger 108 BTHPs, H4350, Lapua brass, and CCI 450 primers.
Load development was a little trickier than with the 6.5×47 Lapua parent cartridge. The accuracy nodes were smaller. However, once I dialed in a load with Hodgdon H4350 and the 108-grain Berger BTHP, the rest was history. The 6×47 rig is now one of the most consistent rifles I own, holding just above 0.3 MOA for 5-round groups. Below is a 100-yard test target with 108-grain Berger BT in the 6×47 Lapua. Five-shot group sizes are (L to R): .369″, .289″, and .405″. The average size was .354″ or .338 MOA. [Editor: We think that is excellent accuracy for a tactical-type rifle shot from bipod.]

Barrel nut system allows “Pre-Fit” barrel installation on a Remington action. CLICK photo to zoom.
REMAGE Project Report by Bill, Rifleshooter.com Editor
Installing a new barrel on your Remington 700 (especially without a lathe) may seem like a daunting task, but thanks to companies like McGowen Precision Barrels, there are easier alternatives. By adopting a Savage-style barrel nut on a 1 1/16″ thread for a Remington 700 receiver, pre-chambered (aka “pre-fit”) barrels can be easily swapped with just a few hand tools. This system is sometimes called a REMAGE conversion (for “REMington savAGE”).
The existing barrel is simply removed from the action (normally the hardest part) and the new barrel is screwed on with the Go Gauge in place. The barrel nut is tightened against the action, headspace verified with the Go Gauge, and you are off to the range. It takes all of the machine work out of the barreling process. Note: the barrel nut has a slightly larger diameter and some stocks may require minor inletting. Also if you are shooting fired brass from another rifle with the same chambering, you should FL-size the brass before loading it for your new pre-fit barrel.

21st Annual Bud Pryor Memorial Match: June 12-14, 2015 Match Report by Richard Grosbier for IBS
It was hot and humid for the 21st Bud Pryor Memorial match. Temperatures were in the high 80s with humidity in the high 90% range all three days. For once we never got rained on. Thunderstorms with high winds were forecast for both Saturday and Sunday. Luckily the storms materialized AFTER the shooting concluded on both days. Wind was not especially strong all weekend but it was tricky and could let off, pick up, or reverse in a heartbeat. Even at 100 yards (on Friday), good shooters lost points.

Three 750s Shot in Varmint for Score Grand Agg
In the Varmint for Score (VFS) 100-200-300 Grand Aggregate John Cascarino was the big winner with a 750-35X. This writer was very happy to see John win a big match. He is a great guy who does an enormous amount of work for all IBS shooters and clubs in his role as IBS Second Vice President. Ricky Read was second with a 750-31X followed closely by Wayne France with 750-28X. It is quite unusual for there to be three 750 scores shot at the “Bud”. I checked the IBS website for 11 years back and found no more than two and frequently there are no 750s shot at the event.
VFS Grand Aggregate Winner John Cascarino.
Top honors in Hunter Class went to Randy Jarvais (below) with a 742-23X. Second went to Gary Long with 742-22X and third to Orland Bunker with 737-25X. Most people had an enjoyable weekend, the threatened thunderstorms never materialized until after the shooting was over.
Hunter Class Winner Randy Jarvais.
Roy Hunter and his “Ugly Stock”
Roy Hunter crafts superb wood-composite, carbon-reinforced stocks. These great-shooting stocks are very popular among benchresters, particularly on the East Coast. Roy complained that every time he built himself a rifle somebody would offer to buy it at a price he could not refuse. That was frustrating so Roy built the odd-looking, calico rifle shown below. He deliberately made it “so ugly nobody that would want it.” At least it does (sort-of) match his multi-color prop-top hat. (Will propeller-top beanies become a hot “must-have” item at Benchrest matches, augmenting downrange wind-flags?)

Day by Day Results:
100 Yards on Friday
A large contingent of Southern shooters were competing at the Bud Pryor for the first time. Initially, it seemed that the southerners might take home all the marbles. At Friday’s 100-yard match, Richard Sissel took first with a nice 250-24X score, followed closely by Ronnie Milford with 250-23X. James Parham, also a Southerner, was third with the first of two 22X scores. Match Director Dean Breeden placed fourth.
In Hunter Class, “Mainiac” Orland Bunker turned in an impressive 250-18X score at 100 yards, shooting with a 6-power scope and 2-1/4″-wide fore-end. To put that in perspective, Orland’s score would have placed him ahead of 60% of the VFS shooters, all of whom benefited from using wider stocks and high-magnification optics.
200 Yards on Saturday
Saturday the targets were moved back to 200 yards and the fun continued. Hall-of-Famer Allie Euber from Vermont took top honors in VFS class with a 250-14X score from his LV rifle. In the Points Race for Score Shooter Of the Year (SSOY), it was another sweep for the Southern contingent. Under IBS rules, only the first rifle one shoots may garner SSOY points. Allie did, in fact, win the 200 VFS stage (with his LV). However, as he shot his HV rifle on the second relay and his LV on the third relay, Allie picked up no SSOY points.
Accumulating the most SSOY points was second place Jerry Powers with 250-13X, followed by third place Jim Cline also with 250-13X. In Hunter Class, Orland Bunker was still on a tear, logging a 248-4X score, followed closely by Gary Long with a 247-6X score. Gary’s score included a one-point crossfire penalty. Had he not cross-fired, Gary would have finished first.
300 Yards on Sunday
Sunday’s 300-yard competition is always the big equalizer at this event. Conditions were relatively mild at Thurmont for the 300-yard match but there was enough wind and mirage to keep scores down. Another Hall of Famer, Harley Baker from Pennsylvania, won the yardage with a nice 250-6X score. Dewey Hancock took second (also with a 250-6X score), followed by John Cascarino with the same score. VFS front-runner Richard Sissel shot well but two dropped points moved him down to 13th at 300.
In all there were only five 250s shot of the 44 guns in attendance. Veteran shooter Ricky Read shot 250-4X and Wayne France turned in a 250-2X performance. In Hunter class, the 100/200 front runner Orland Bunker struggled at 300 yards. K.L. Miller, who only shot the 300-yard stage, won Hunter class with a 249-5X. Miller was attempting to break the 300-yard Hunter record and almost did. Randy Jarvais was second with a 247-2X.
Target Cake is a Big Hit
Ready, Aim, Eat. A special hand-decorated cake featured a six-bull target (complete with sighter shots). Beautifully presented, the Bud Pryor bullseye cake was a huge hit with match attendees.

For a number of years I drooled over every .50 BMG caliber rifle that I came across, I read every article I could find and determined that ‘Someday’ I was going to have one. Well I finally took the plunge and in 2002 I purchased my first ‘Big 50’. Almost immediately I joined the Fifty Caliber Shooters Association (FCSA) and I have since come to immensely enjoy shooting this challenging cartridge and associating with some of the best people on earth.
With barrels, one wonders “Can a little more length provide a meaningful velocity gain?” To answer that question, Rifleshooter.com performed an interesting test, cutting a .308 Win barrel from 28″ all the way down to 16.5″. The cuts were made in one-inch intervals with a rotary saw. At each cut length, velocity was measured with a Magnetospeed chronograph. To make the test even more interesting, four different types of .308 Win factory ammunition were chronographed at each barrel length.
Test Barrel Lost 22.7 FPS Per Inch (.308 Win Chambering)
How much velocity do you think was lost, on average, for each 1″ reduction in barrel length? The answer may surprise you. With a barrel reduction from 28″ to 16.5″, the average speed loss of the four types of .308 ammo was 261 fps total. That works out to an average loss of 22.7 fps per inch. This chart shows velocity changes for all four ammo varieties:
Summary of Findings: The average velocity loss per inch, for all four ammo types combined, was 22.7 FPS. By ammo type, the average loss per inch was: 24.6 (Win 147 FMJ), 22.8 (IMI 150 FMJ), 20.9 (Fed GMM 168gr), and 22.5 (Win 180PP).
Interestingly, these numbers jive pretty well with estimates found in reloading manuals. The testers observed: “The Berger Reloading manual says for the 308 Winchester, ‘muzzle velocity will increase (or decrease) by approximately 20 fps per inch from a standard 24″ barrel’.”
How the Test Was Done
The testers described their procedure as follows: “Ballistic data was gathered using a Magnetospeed barrel mounted ballistic chronograph. At each barrel length, the rifle was fired from a front rest with rear bags, with five rounds of each type of ammunition. Average velocity and standard deviation were logged for each round. Since we would be gathering data on 52 different barrel length and ammunition combinations and would not be crowning the barrel after each cut, we decided to eliminate gathering data on group sizes. Once data was gathered for each cartridge at a given barrel length, the rifle was cleared and the bolt was removed. The barrel was cut off using a cold saw. The test protocol was repeated for the next length. Temperature was 47° F.”
CLICK HERE to Read the Rifleshooter.com Test. This includes detailed charts with inch-by-inch velocity numbers, multiple line charts, and complete data sets for each type of ammo. Rifleshooter.com also offers ballistics graphs showing trajectories with different barrel lengths. All in all, this was a very thorough test by the folks at RifleShooter.com.
Much Different Results with 6mmBR and a Longer Barrel
The results from Rifleshooter.com’s .308 barrel cut-down test are quite different than the results we recorded some years ago with a barrel chambered for the 6mmBR cartridge. When we cut our 6mmBR barrel down from 33″ to 28″, we only lost about 8 FPS per inch. Obviously this is a different cartridge type, but also our 6mmBR barrel end length was 5″ longer than Rifleshooter.com’s .308 Win start length. Velocity loss can be more extreme with shorter barrel lengths (and bigger cartridges). Powder burn rates can also make a difference.

If you shoot a .308 Win, or any cartridge that uses a Large Rifle (LR) primer, you should read an important new article by Laurie Holland in Target Shooter Magazine. Holland, a talented shooter from the UK, tested no less than sixteen (16) different large primer types using a custom F-TR target rifle shot from the bench. Laurie loaded .308 Win ammo* with 16 LR primer varieties and then tested for average velocity, ES/SD, and group size. This may be the most comprehensive and thorough LR primer test ever done. Here are the primer types tested:
CBC Magtech 9½
CCI 200 LR
CCI BR2 Match
CCI 250 Magnum
Federal 210M Match
Federal 215M Magnum Match
Fiocchi Large Rifle
Kynoch Large Rifle
Murom KVB-7 (PMC LR)
Norma Superflash LR
PMC LR Magnum
Remington 9½ LR
Remington 9½ M Magnum
Sellier & Bellot LR
Test Rig: Osprey Rifles-built F-TR rifle with Savage PTA action, 32″ Bartlein 1:12″-twist ‘Heavy Palma’ barrel, and Dolphin Gun Company modular stock with an F-Open/Benchrest fore-end.
Some of Laurie’s results may surprise you. For example, would you guess that Sellier & Bellot primers had the lowest ES, by a significant margin? And get this, among ALL the primers tested, Rem 9½M Magnum primers produced the lowest velocity, while Rem 9½ LR (non-magnum) primers yielded the highest velocity. (The total velocity spread for all primers was 35 fps). That’s counter-intuitive and it’s odd that Rems were at opposite ends of the speed spectrum among ALL primers tested.
“The rationale for doing side-by-side tests is to see what effect primer choice has on ballistics, i.e. average velocities and MV consistency. There are a great many views on the subject, a few based on tests (including primer flame photography) but most apparently hearsay.” — Laurie Holland
Every serious hand-loader should definitely read the full test results to understand Laurie’s methodology and get all the details. This is an important test, with significant findings. But if you can’t spare the time right now, here are some highlights below:
Primer with Lowest Velocity: Remington 9½ M Magnum (2780 fps)
Primer with Highest Velocity: Remington 9½ LR (2815 fps)
Primer with Lowest ES/SD: Sellier & Bellot LR (12/3.1 fps)
Primer with Highest ES/SD: Remington 9½ M Magnum (47/14.0 fps)
Primer with Smallest Group Size: Remington 9½ LR (0.43″ average, three 5-shot groups)
Primer with Biggest Group Size: CBC Magtech 9½ (0.7″ average, three 5-shot groups)
Editor’s Comment: Laurie shot three, 5-shot groups at 100 yards with each primer type. The average group size for the top six primers varied by only 0.10″ (0.43″ to 0.53″), so one can’t conclude that one type is much better than another. Total group size variance (from best to worst) was 0.27″.
“The biggest surprise to me … came from an elderly (at least 10 years) lot of Czech Sellier & Bellot standard caps with an ES of 12 and SD of 3.1 fps, way below those of the nearest competitor. By contrast to the Fiocchis, they were an almost slack fit in the cases and this may have contributed to their consistent performance.” — Laurie Holland
NOTE: Values in chart are based on 15-Shot strings. The ES/SD numbers will therefore be higher than is typical with five-shot strings.
Testing 16 primer types was a huge task — we commend Laurie for his hard work and thoroughness. This extensive test is an important contribution to the “knowledge base” of precision shooting. Laurie’s findings will doubtless influence many hand-loaders who hope to produce more consistent ammunition, or achieve better accuracy. Credit should also be given to Target Shooter Magazine for publishing the results. Well done gentlemen…
*Reloading method for Test Ammo: “Test batches consisted of 16 or 17 rounds for each primer, charges thrown by an RCBS ChargeMaster and checked on lab-quality electronic scales, adjusted if necessary to within ± 0.04gn, so any charge weight variation would be under 0.1 grain which equates here to 5 fps.”

In the just-released June 2015 issue of Shooting Sports USA, you’ll find an excellent profile of SFC Emil Praslick III, a legendary figure in American shooting. As a marksmanship instructor and coach for the USAMU, Praslick has been a mentor for many of America’s greatest marksmen. Praslick has also served as a wind coach for many civilian teams over the years, guiding them to victory in high-level championship events. SFC Praslick plans to retire later this year, when SFC Shane Barnhart will take over as coach of the USAMU Service Rifle Team.
In a wide-ranging Shooting Sports USA interview with writer John Parker, SFC Praslick offers many interesting insights. Here are some highlights (after the jump):
Based on the questions we get on a daily basis on our 800 (Customer Support) line, twist is one of the most misunderstood subjects in the gun field. So let’s look deeper into this mystery and get a better understanding of what twist really means.
When you see the term 1:14″ (1-14) or 1:9″ twist, just exactly what does this mean? A rifle having a 1:14″ twist means the bullet will rotate one complete revolution every fourteen inches of the barrel. Naturally a 1:9″ turns one time every nine inches that it travels down the barrel. Now, here’s something that some people have trouble with. I’ve had calls from shooters thinking that a 1:14″ twist was faster than a 1:9″ because the number was higher with the 1:14″. The easiest way to remember this is the higher the number, the slower the twist rate is.
Some folks say you haven’t really mastered marksmanship unless you can hit a target when standing tall ‘on your own hind legs’. Of all the shooting positions, standing can be the most challenging because you have no horizontally-solid resting point for your forward arm/elbow. Here 10-time National High Power Champ Carl Bernosky explains how to make the standing shot.
Carl Bernosky is one of the greatest marksmen in history. A multi-time National High Power Champion, Carl has won ten (10) National High Power Championships in his storied shooting career, most recently in 2012. In this article, Carl provides step-by-step strategies to help High Power shooters improve their standing scores. When Carl talks about standing techniques, shooters should listen. Among his peers, Carl is regard as one of the best, if not the best standing shooter in the game today. Carl rarely puts pen to paper, but he was kind enough to share his techniques with AccurateShooter.com’s readers.
If you are position shooter, or aspire to be one some day, read this article word for word, and then read it again. We guarantee you’ll learn some techniques (and strategies) that can improve your shooting and boost your scores. This stuff is gold folks, read and learn…
How to Shoot Standing by Carl Bernosky
Shooting consistently good standing stages is a matter of getting rounds down range, with thoughtfully-executed goals. But first, your hold will determine the success you will have.
1. Your hold has to be 10 Ring to shoot 10s. This means that there should be a reasonable amount of time (enough to get a shot off) that your sights are within your best hold. No attention should be paid to the sights when they are not in the middle — that’s wasted energy. My best hold is within 5 seconds after I first look though my sights. I’m ready to shoot the shot at that time. If the gun doesn’t stop, I don’t shoot. I start over.
2. The shot has to be executed with the gun sitting still within your hold. If the gun is moving, it’s most likely moving out, and you’ve missed the best part of your hold.
3. Recognizing that the gun is sitting still and within your hold will initiate you firing the shot. Lots of dry fire or live fire training will help you acquire awareness of the gun sitting still. It’s not subconscious to me, but it’s close.
4. Don’t disturb the gun when you shoot the shot. That being said, I don’t believe in using ball or dummy rounds with the object of being surprised when the shot goes off. I consciously shoot every shot. Sometimes there is a mistake and I over-hold. But the more I train the less of these I get. If I get a dud round my gun will dip.* I don’t believe you can learn to ignore recoil. You must be consistent in your reaction to it.
5. Know your hold and shoot within it. The best part of my hold is about 4 inches. When I get things rolling, I recognize a still gun within my hold and execute the shot. I train to do this every shot. Close 10s are acceptable. Mid-ring 10s are not. If my hold was 8 inches I would train the same way. Shoot the shot when it is still within the hold, and accept the occasional 9. But don’t accept the shots out of the hold.
6. Practice makes perfect. The number of rounds you put down range matter. I shudder to think the amount of rounds I’ve fired standing in my life, and it still takes a month of shooting standing before Perry to be in my comfort zone. That month before Perry I shoot about 2000 rounds standing, 22 shots at a time. It peaks me at just about the right time.
This summarizes what I believe it takes to shoot good standing stages. I hope it provides some insight, understanding, and a roadmap to your own success shooting standing.
— Good Shooting, Carl
* This is very noticeable to me when shooting pistol. I can shoot bullet holes at 25 yards, but if I’ve miscounted the rounds I’ve fired out of my magazine, my pistol will dip noticeably. So do the pistols of the best pistol shooters I’ve watched and shot with. One might call this a “jerk”, I call it “controlled aggressive execution”, executed consistently.

Our friend Vince Bottomley in the UK has written an excellent article for Target Shooter Magazine. Vince offers “solid-gold” advice for new F-TR and F-Open shooters. Vince reviews the cartridge options, and offers suggestions for a shooter’s first (and hopefully affordable) F-Class rifle. Vince also reviews various bipod choices for F-TR and discusses optics options (from $300 to $3000).
Sinclair Internationalhas released an interesting article about Case Concentricity* and bullet “run-out”. This instructional article by Bob Kohl explains the reasons brass can exhibit poor concentricity, and why high bullet run-out can be detrimental to accuracy.
Concentricity, Bullet Alignment, and Accuracyby Bob Kohl
The purpose of loading your own ammo is to minimize all the variables that can affect accuracy and can be controlled with proper and conscientious handloading. Concentricity and bullet run-out are important when you’re loading for accuracy. Ideally, it’s important to strive to make each round the same as the one before it and the one after it. It’s a simple issue of uniformity.
