F-Class shooting (both F-Open and F-TR) is one of the fastest-growing forms of rifle competition. Each season many new shooters hit the line and attendance at the big matches increases every year. But if you’re new to the game, you may ask “Where can I shoot an F-Class match?”. Well, Forum member Rod V. (aka Nodak7mm) has compiled a useful list of 112 ranges throughout the USA where F-Class matches are held. With venues from Alabama to Wyoming — you should find an F-Class program not too far from home. The list, in Excel spreadsheet format, provides range locations and weblinks (where available). Click the link below to download the F-Class Range List (.xls file):
Download F-Class Range List, Revision 20 (12/24/2015) (.XLS file, right click to “save as”)
Note — this list, now in its 19th Revision, is augmented regularly, but info is still being gathered. No claim is made that the list is comprehensive. But it still covers the the lion’s share of the important F-Class venues nationwide. If you know of a range that should be added to the list, please post the location on our F-Class Range List Forum thread. Rod will update the list as new range info is received. Rod writes: “Range information is wanted and welcomed. I would like your help on collecting specific info on Clubs/Ranges where known F-Class matches are held.” Here’s a partial sample from Rod’s list:

Here’s your chance to win $50,000 and become a TV star. The Outdoor Channel’s new television show, American Marksman, showcases a series of shooting competitions leading to a big-money National Championship. American Marksman gives amateur shooters the chance to win cash, gear and fame. The top shooter will win $50,000 and earn the title of “American Marksman”.
The competition begins with local qualifiers starting in March 2016 at locations across the country. There will be three stages: local qualifying matches, regional championships, and a National Championship. The entire process will be filmed for later broadcast on the Outdoor Channel beginning in December 2016. The nine regional championships will be revealed as locations are finalized.
“If you ever wanted to enter a shooting competition and thought it was too intimidating or too expensive – then this is your chance to show the world what you’ve got,” said producer Michael Bane, Outdoor Channel. “For only $20 at the local level, you get the chance to try to qualify with other amateurs in a relaxed, safe environment and the best of you will meet in a … National Championship with TV cameras rolling. The person who earns the title of ‘American Marksman’ walks away with $50,000.”
How to Participate: To get involved in the American Marksman competition, you can Register Now at AmericanMarksman.com. You need to have your own .22 LR gun and 50 rounds of ammo for the local qualifier (you can rent a gun from the local range if needed). American Marksman will provide firearms and ammo for the Regional and National championships, should you advance. NOTE: American Marksman is an amateur-only event series with strict eligibility guidelines.
Where to Compete: The local qualifying rounds begin in March, 2016 at nearly 200 ranges in 47 states. CLICK HERE for a list of Participating Ranges, which can be sorted by state.
“The local qualifying level is designed not only to appeal to more seasoned shooters, but also to attract new people into the shooting sports by offering a low-cost and less intimidating way to get involved in competition,” explained show Producer Michael Bane.
Competition Categories: American Marksman offers four categories of competition: Men’s Open, Women’s Open, Junior (12-16) and Military/Law Enforcement. Pick the category that fits you. At the National Championship, the best shooters from each of the categories will be pitted against each other to compete for $50K and the “American Marksman” title.
Course of Fire: Each round will feature .22 LR rimfire courses of fire. As the competitors progress, they will be challenged with different calibers, targets and courses of fire. Advancing shooters will go to one of nine regional championships, which begin in June and proceed through August with the National Championship taking place in early 2017.

Here’s a photo of the private range where a match was to be held…
“Local Shoot Cancelled, Everything Cancelled….” That was the report from Forum member “Dixie PPC”. He was planning to attend a 600/1000-yard match. Well, there was just a little bit too much of the white stuff this morning. The match was cancelled, and he told us “pretty much everything was cancelled”.
The local Interstate was closed down because of the snow…
Conditions were bleak and cold…
Despite the snow, things weren’t completely cancelled on DixiePPC’s farm: “My Farm was not shut down… Cattle gotta’ eat.”

SHOT Show, the firearms industry trade show, is a huge event. There are more guns and shooting accessories than you can possibly imagine. On Thursday we saw everything from a giant CADEX .50 BMG with a 24″-long suppressor to a tiny Kahr .380, the thinnest carry gun in production. Here are some highlights from Day Three, a combination of old and very, very new. McMillan has a new, as-yet-unnamed tactical stock, Walther showcased an amazing electronic trigger, and Uberti revived America’s Wild West heritage with a line of single-action revolvers.
CZ 455 Tactical/Varmint Rimfire Rifles
CZ USA still continues to offer some of the best .22 LR rifles for cross-training and tactical rimfire games. The CZ 455 Varmint Tacticool and Varmint Precision Trainer (Camo) feature proper, full-size stocks (with adult-scale ergonomics) so these rimfires look and feel like a centerfire tactical rig. CZ 455s have smooth actions and crisp triggers.
Walther LG400 Air Rifle with Electronic Trigger
Look carefully — this Walther LG400 Alutec air rifle is different than any gun you’ve ever shot. You see it has an ELECTRONIC trigger. This sophisticated, battery-powered trigger offers a super-precise, super-light release (it’s more a “touch” than a “pull”). For top-level international and Olympic shooters, the electronic trigger can offer a competitive advantage. Later this year Walther will offer an electronic trigger in its top-of-the-line smallbore rifle.
“Name This Stock” — New Tactical Stock from McMillan
Kelly McMillan, president of McMillan Fiberglass Stocks is holding the latest tactical stock from McMillan. It features a girder-style open fore-end that fits any barrel contour. At the rear, the stock boasts an adjustable cheekpiece along with a straight toe for riding a sandbag. Interestingly, this stock has no name (as yet). At SHOT Show, McMillan is running a “Name This Stock” contest. The winner will receive a free stock.
Giant Super-Sized Scope at Zeiss Booth
At its booth, Zeiss displayed what must be the world’s largest rifles-scope replica. This giant scope, as big as a totem pole, certainly did draw the attention of anyone who walked by. The big news at Zeiss this year is the Victory V8 line of scopes with 8X zoom ratio.
Uberti Classic Single Action Pistols
We love vintage-style revolvers. This year Uberti offered a beautiful array of single-action pistols in a variety of styles. Along with its line of “Wild West” repro pistols, Uberti makes excellent lever guns based on classic Winchester designs. This editor owns two Uberti lever-action rifles, and they are both beauties.
Anschutz Model 9015 Competition Air Rifle
Our friend Steve Boelter, President of Anschutz North America, showed us the latest and greatest competition rifles from the respected German gun-maker. In this photo, Steve is holding the new Anschutz 9015 air rifle. Above is the new, top-of-the-line Anschutz smallbore target rifle. In a week or so we’ll release a video showing the details of both these rifles.
SHOT Scenery — From Russia with Love
It wouldn’t be SHOT without a few Booth Babes, or should we say Booth Babe-bushkas. These charming young ladies really ARE from Russia. Yuliya, on the right, hails from far-away Vladivostok in Siberia. She said she appreciated the warmer weather in Las Vegas.
Tikka T3 Compact Tactical Rifle for the Canadian Rangers
On display at the SAKO booth was the Tikka T3 Compact Tactical Rifle which has been adopted by the Canadian Rangers. This will replace the Ranger’s beloved, but antiquated Lee-Enfield rifles. The Canadian Rangers, an element of the Canadian Armed Forces (CAF) Reserve, serve as the CAF’s eyes and ears in sparsely-settled northern and coastal areas of Canada. The Rangers have helped secure Canada’s hinterlands since 1947.
Browning “Hell’s Canyon” Gun Vaults
Browning showcased a series of large gun safes with much-enhanced fire-proofing and thicker steel walls. The new “Hell’s Canyon” Series of gun vaults offer 40% thicker steel plus 2 – 3 times the fire protection of typical gun safes. These “Hells Canyon”-series safes are impressive.
Kim Rhode — Olympic Gold Medal Winner
We had a chance to interview shotgun superstar Kim Rhode, who has won Gold Medals at multiple Olympic Games. She told us some very interesting facts. For example, did you know that roughly 70% of females are left-eye dominant? Kim revealed some techniques that right-handed, cross-dominant shooters can use to improve their scores. We’ll reveal that in an upcoming video interview with Kim, shown here at the autograph table with some of her Olympic medals.

Savage’s new 10/110 BA Stealth tactical rifle
Here are eleven of the more interesting products (and people) we saw on Day Two of SHOT Show. This is only the tip of the iceberg folks. With 12.5 miles of aisles, and over 1600 Exhibitor booths, we can only show a tiny fraction of the products on display. There are tactical rifles and gear everywhere in sight. We also found some interesting target systems and reloading tools. Stay tuned for more product previews tomorrow from SHOT Show at the Sands Convention Center.
Savage 10/110 BA Stealth
You asked for it — here it is — the new Savage 10/110 BA Stealth. This new rifle features a strong yet light aluminum chassis that accepts AR-compatible rear sections. Savage says the actions have been “factory blueprinted”. Available chamberings are: 6.5 Creedmoor, .308 Winchester, .300 Win Magnum, and .338 Lapua Magnum. We shot this rifle, in .308 Win, at Media Day and we liked the ergonomics.
NEW Alliant Reloder 16 Powder
Alliant’s engineers showed us “top-secret” data charts comparing various popular powders. This new Reloder 16 is one of the most temp-stable propellants ever created. Burn rate is slightly faster than H4350. Initial accuracy results have been very promising. AccurateShooter.com will be testing this powder very soon. Stay tuned.
Savage A17 in Laminated Thumbhole Stock
Here is the 17 HMR Savage A17 in new laminated, thumbhole stock. We want one. The wood-stocked A17 balances well and feels good. This is a definite upgrade over the original plastic stock.
Vortex 6-24x50mm FFP Razor HD
Vortex unveiled a very impressive new tactical scope, the 6-24x50mm Razor HD. Vortex says this top-of-line optics was engineered to compete with anything on the market — including the big-name German brands. The glass was excellent, and we loved the fact the elevation turret offers a full 25 MOA of elevation in one rotation. Great feature.
Pardini Competition Air Rifle
Design for Olympics-level competition, this new Pardini is one of the most sophisticated air rifles ever made. It has a very sophisticated loading system that allow you to load pellets without changing your hold on the rifle. It was designed with input from Olympic Champion shooters.
Ken Oehler and the New System 88
Chronograph Guru Ken Oehler explained the capabilities of his “enterprise-grade” System 88. This combines a proof-channel chronograph at the firing line with sonic sensors at 1000 yards (and other distances in between if desired). This allows very precise calculation of true bullet BCs.
$38,000 JANZ Multi-Barrel, Multi-Caliber Revolver
You are looking at the world’s most expensive wheelgun, the JANZ multi-caliber system. Custom-built for each customer, this amazing revolver shoots multiple cartridge types — even rimfire. As far as we know this is the only revolver in the world that shoots .22 LR rimfire as well as centerfire cartridges up to .500 SW. The builder, JANZ-Praszisionstechnik GmbH, will craft the gun with as many barrels and cylinders as the owner wants. As shown in the photo, the price is around $38,000.
New Bullets from Sierra
Sierra Bullets had its new Tipped MatchKings on display, and well as the very impressive new 7mm 183-grain MatchKings, which are “tip-uniformed” at the factory. Lester Bruno shot some of these 183-grainers and said they held amazing waterline at 1000 yards, indicating that the bullet-to-bullet BC is very consistent. Listed G1 BC for the 183gr MK, SKU #1983, is .707.
Jerry Miculek, World’s Fastest Wheelgunner
We met up with the legendary Jerry Miculek at the Hornady Booth. The world’s fastest wheelgunner (and a darned good rifleman too) had fans lined up for autographs. What’s the secret to Jerry’s success? Hard work, hands of steel, and a positive attitude.
New Throat Erosion Gauge from PT&G
Pacific Tool and Gauge had a bunch of new products on display. One item that caught our eye was an interesting Throat Erosion Gauge. Index marks on the main shaft let you determine, with precision, how much your throat has moved. Screw-on, caliber-specific pilots let you gauge all popular calibers.
Sig Sauer 5-25x52mm “Whiskey 5″ SFP Scope
We were very impressed with Sig Sauer’s optics, which offer a lot of capability for the price. The new 5-25x52mm Whiskey 5 optic offers positive controls and a nice illuminated reticle center (good for low light). The “street price” is around $1200.00 – $1300.00. READ Full Review Here.
January 20th, 2016
SHOT Show offers a unique opportunity to see a host of new products AND reconnect with old friends in the shooting world. We met with our friends John Krieger (Krieger Barrels), Ian Kelbly (Kelblys.com), Dave Kiff (PT&G), and Eric Stecker (Berger Bullets). On SHOT Show Day One we saw many interesting items, including a new $1500.00, 15-60x52mm comp scope from Vortex and the amazing Bix’n Andy Elypse action. That 15-60X Vortex should prove a great choice for F-Class competition and the Elypse “raises the bar” for lightweight benchrest actions.
Vortex Optics — “Golden Eagle” 15-60x52mm Competition Scope
Everyone involved in long-range target shooting should check out this New Vortex “Golden Eagle” 15-60x52mm scope. It offers a 4X zoom ratio with 60X max magnification, with an affordable street price of around $1500.00. That undercuts the competition from other major brands by hundreds of dollars. Two reticle options will be offered, a fine cross-hair and one with MOA-based hold-over lines. We’ll provide a more complete report soon….
Howa — Mini-Action Bolt Gun
We finally got our hands on the Mini-action Howa, a very nice little rifle. I immediately noticed that the bolt is extremely smooth — really nice. The HACT 2-stage trigger is excellent — just about perfect for a varmint rifle. The action is nearly an inch shorter than a conventional “short action” so bolt movement is shorter. The rifle is currently offered in .204 Ruger and .223 Remington, and Howa may release a .222 Remington, 6.5 Grendel and 7.62×39 version in the future. Street price on this rifle is around $600.00. I give this rifle two thumbs up, way up. I want one.
Kelbly’s — New Composite GRS Stocks
Kelbly’s is the North American distributor for GRS stocks from Norway. For 2016 GRS has introduced advanced composite stocks. These share the ergonomic design of GRS wood stocks, but offer greater strength, rigidity, and durability. If you are looking for an advanced composite-matrix stock for hunting and tactical applications, you should check out this new GRS. We were very impressed.
Bix’n Andy — Titanium Elypse Action
This may be the most sophisticated benchrest action ever created. The new Bix’n Andy Elypse action will be offered in both stainless and Titanium (shown above). The action features an elliptical profile and a drop port. The trigger, sold separately, is superb, absolutely superb. There are many unique features, such as the flared loading port ramp and easy-change bolt handle. This is truly the Rolls-Royce of precision actions.
Shilen — AR and Savage Drop-in Barrels
We visited the Shilen booth and chatted with Wade Hull, Shilen’s President. Wade explained that Shilen now offers a variety of Drop-in Barrels for Savages as well as “large-format” ARs (AR10 type rifles in 308-family chamberings). Wade also noted that Shilen has streamlined its production process, so wait-time on chambering work has been reduced significantly.
Stocky’s Stocks — New 3D-Printed Prototype Stock
3D Printing and Rapid Prototyping has come to the gunstock world. Stockys Stocks showed off a high-tech 3D-printed prototype of its new tactical stock with removable cheekpiece. We also checked out Stocky’s impressive Long Range composite stocks. Very strong, and very rigid, these stocks feature a CNC-milled aluminum bedding block. These are a stunning value for just $199.99.
RAS Tuners — Combo Tuner + Muzzle Brake
Tuners work — though it may take a bit of time and effort to dial in your tune. The RAS Tuner system combines a sensitive tuner with a removable muzzle brake. There are systems for ARs as well as bolt guns. The inventor of the RAS says he has seen significant reductions in group size.
Tactical Solutions — High-Bling Rimfire Rifles and Pistols
If bling is your thing, then Idaho-based Tactical Solutions has you covered. This company offers a wide variety of firearms including .22 LR rimfire target pistols and rifles. The rifle in this photo is configured with a permanent barrel extension that makes it ATF-compliant. But the actual barrel is threaded below the barrel extension so you can add a suppressor and still have a short overall-length “fun gun”.
Hygenall — LeadOff Products
Anyone who does a lot of shooting may be exposed to lead residues. Lead is a tough substance to remove from human skin. We chatted with the scientists who created these LeadOff products and were quite impressed. The product uses sophisticated chemistry to “grab and remove” the lead molecules on your skin. This product has earned health agency certifications.
Champion — Plinking Targets for Fun Shooting
Among all the “Operator-ready” Black Rifles and Tactical gear, it was nice to see a display dedicated to the simple fun of shooting. As kids, we all started our shooting careers plinking with a BB Gun or a simple rimfire rifle. Champion makes a variety of reactive targets that are great for plinking.
January 19th, 2016
Scores of manufacturers showcase their products at the SHOT Media Day event, held each year in Boulder City, Nevada. This year we saw some legendary names (such as Colt and Winchester), as well as new, 21st-century gun-makers (such as Tracking Point). Savage and Kimber had some surprising new offerings, and we saw impressive new optics from Zeiss and Minox. There were some interesting trends. Many firearms were equipped with “factory” suppressors. Ruger, much to our surprise, showcased a Ruger 10/22 takedown rifle fitted with a Ruger-branded suppressor. It was extremely quiet. Many of the handgun manufacturers, including Ruger and Walther, supplied ammunition with composite polymer matrix bullets. These bullets are significantly lighter than conventional pistol bullets of the same caliber (the reduced bullet mass did lessen felt recoil with 9mm and 45 acp pistols). The polymer bullets are lead-free, and they don’t ricochet, so they are both more “eco-friendly” and safer when used on steel targets.
New Savage 110 BA Stealth Rifle
Savage unveiled a modern, “monolithic” metal-chassis tactical rifle. Designed to compete with the Ruger Precision Rifle (RPR), the new Savage 110 BA Stealth has an AR-type hand grip, skeletal buttstock, and a low-profile vented forearm. This rifle will be offered in .308 Winchester and 6.5 Creedmoor while a slightly bigger model will be offered in .300 Win Mag and .338 Lapua Magnum. Savage says that all the 110 BA Stealth models will feature “factory blue-printed actions” for improved accuracy. MSRP varies from $1200 to $1600 depending on caliber and configuration. It should be available starting next month.
The model on display, chambered in .308 Winchester, proved accurate in the hands of Ed M. of 65guys.com. Ed liked the trigger and the fact that the rifle uses PMags. The stock, based on a design by Drake Associates, is very light but also very rigid. Ed thought this stock would work well on barricades in tactical matches. Steve L. of 65guys.com said there is “pent-up demand” for a rifle like this, and he predicts the 110 BA Stealth will be a big seller for Savage.
New K6 Revolver from Kimber
Kimber, known for its 1911-type semi-auto pistols, has introduced an all-new K6 .357 magnum carry revolver. Kimber’s hammerless wheelgun was very nicely crafted and had one of the smoothest double-action pulls we’ve tried. The trigger pull was long, but very consistent and smooth. With the Kimber, you don’t feel a series of “stages” or transitions as you do with most other double-action revolvers. The other impressive thing about the new revolver is the finish — the stainless is very smooth and shiny, the result of “much hand polishing” according to Kimber engineers.
Ruger 10/22 Takedown with Factory Suppressor
The most fun we had all day was at the Ruger booth. There we got to test a Ruger 10/22 Takedown fitted with a Ruger-branded factory-made suppressor. This little rifle was a hoot to shoot, and with the suppressor in place it was amazingly quiet. We really liked this set-up and the take-down system worked brilliantly — just pull one lever, then twist and the barrel section comes off. For those states where you can own a suppressor, we strongly recommend this configuration. The “can” is sold separately and buyer must still comply with all applicable state and Federal laws.
Zeiss Victory V8 4.8-35x60mm Rifle Scope
Zeiss showed off its impressive Victory V8 line of riflescopes. These offer an 8X zoom ratio, with handy BDC turrets — just dial the yardage indicated on the turret (you can custom-order BDC rings calibrated for your favorite load). The new V8 scopes offer many impressive features. We shot a rifle fitted with the new 4.8-35x60mm V8, which features a very beefy 36mm main tube. The glass was bright and ultra-sharp. Zeiss claims 92% light transmission. Fiber optic technology provides a very precise red dot in the center of the reticle. This was visible even in bright sunlight. Zeiss will offer three other V8 models: 1-8x30mm, 1.8-14x50mm, and 2.8-20x56mm.
APO .338 Lapua Magnum
Bigger is apparently better when it comes to serious tactical rifles. There were quite a few rifles chambered for the powerful .338 Lapua Magnum Cartridge. We tried out a .338 LM from Ashbury Precision Ordnance. With some help from a laser rangefinders, we were able to put rounds on a large steel plate at 960 yards. The trigger was nice and the suppressor reduced felt recoil. This was a nice rifle, with a comfortable cheek-piece and ergonomic grip.
Minox MD 88 Spotting Scope
We noticed a BIG front objective on a brand-new Minox spotting scope — one of only two in the country. This new spotter features low-dispersion glass and dual focusing rings — a large “fast focus” ring and a second smaller, fine focus ring. The price, including 20-60X eyepiece, will be around $1750.00. Jason Baney, who works for EuroOptics, says this new Minox spotting scope compares well with other spotters that cost considerably more.
Blaser R8 Professional Thumbhole Fancy Wood
If there was one rifle I wanted to take home with me, it was this nice Blaser R8 “Professional Success” model with a fancy wood new thumbhole stock. This rifle was very comfortable in all shooting positions. The gun balanced well and the straight-pull Blaser action is fun to use. It can be cycled rapidly without disturbing your position on the rifle.
This is always something new and unusual on display at Media Day at the range. This tracked one-man rig provides all-terrain mobility so disabled persons can enjoy hunting and wilderness recreation.
January 18th, 2016
We will be interviewing Bryan Litz of Applied Ballistics tomorrow at SHOT Show in Las Vegas. As a sneak preview of some of the topics we’ll cover, here are some highlights of some important, original research conducted by Bryan and his Applied Ballistics team. Bryan wanted to know how much velocity was altered by twist rate. The “real world” test results may surprise you….
The Applied Ballistics team tested six (6) same-length/same-contour Bartlein barrels to observe how twist rate might affect muzzle velocity. This unique, multi-barrel test is featured in the book Modern Advancements in Long Range Shooting. That book includes many other fascinating field tests, including a comprehensive chronograph comparison.
Barrel Twist Rate vs. Velocity — What Tests Reveal
by Bryan Litz
When considering barrel twist rates, it’s a common belief that faster twist rates will reduce muzzle velocity. The thinking is that the faster twist rate will resist forward motion of the bullet and slow it down. There are anecdotal accounts of this, such as when someone replaces a barrel of one brand/twist with a different brand and twist and observes a different muzzle velocity. But how do you know the twist rate is what affected muzzle velocity and not the barrel finish, or bore/groove dimensions? Did you use the same chronograph to measure velocity from both barrels? Do you really trust your chronograph?
Savage Test Rifle with Six Bartlein Barrels
Most shooters don’t have access to the equipment required to fully explore questions like this. These are exactly the kinds of things we examine in the book Modern Advancements in Long Range Shooting. In that book, we present experiments conducted in the Applied Ballistics lab. Some of those experiments took on a “Myth Buster” tone as we sought to confirm (or deny) popular pre-conceptions. For example, here’s how we approached the question of barrel twist and muzzle velocity.
Six .308 Win Barrels from Bartlein — All Shot from the Same Rifle
We acquired six (6) barrels from the same manufacturer (Bartlein), all the same length and contour, and all chambered with the same reamer (SAAMI spec .308 Winchester). All these barrels were fitted to the same Savage Precision Target action, and fired from the same stock, and bench set-up. Common ammo was fired from all six barrels having different twist rates and rifling configurations. In this way, we’re truly able to compare what effect the actual twist rate has on muzzle velocity with a reasonable degree of confidence.
Prior to live fire testing, we explored the theoretical basis of the project, doing the physics. In this case, an energy balance is presented which predicts how much velocity you should expect to lose for a bullet that’s got a little more rotational energy from the faster twist. In the case of the .30 caliber 175 grain bullets, the math predicts a loss of 1.25 fps per inch-unit of barrel twist (e.g. a 1:8″ twist is predicted to be 1.25 fps slower than a 1:9″ twist).
Above, data shows relationship between Twist Rate and Muzzle Velocity (MV) for various barrel twist rates and rifling types. From fast to slow, the three 1:10″ twist barrels are: 5R (canted land), 5 Groove, 5 Groove left-hand twist.
We proceeded with the testing in all 6 barrels from 1:8” to 1:12”. After all the smoke cleared, we found that muzzle velocity correlates to twist rate at the rate of approximately 1.33 fps per inch of twist. In other words, your velocity is reduced by about 5 fps if you go from a 1:12” twist to a 1:8” twist. [Editor: That’s a surprising number — much less than most folks would predict.] In this case the math prediction was pretty close, and we have to remember that there’s always uncertainty in the live fire results. Uncertainty is always considered in terms of what conclusions the results can actually support with confidence.
 This is just a brief synopsis of a single test case. The coverage of twist rates in Modern Advancements in Long-Range Shooting is more detailed, with multiple live fire tests. Results are extrapolated for other calibers and bullet weights. Needless to say, the question of “how twist rate affects muzzle velocity” is fully answered.
Other chapters in the book’s twist rate section include:
· Stability and Drag – Supersonic
· Stability and Drag – Transonic
· Spin Rate Decay
· Effect of Twist rate on Precision
Other sections of the book include: Modern Rifles, Scopes, and Bullets as well as Advancements in Predictive Modeling. This book is sold through the Applied Ballistics online store. Modern Advancements in Long Range Shooting is also available in eBook format in the Amazon Kindle store.
