Velocity vs. barrel length — How much speed will I sacrifice with a shorter barrel? Hunters and competition shooters often ask that. Today we DO have solid answers to that question for many cartridge types thanks to Rifleshooter.com.
Bill, Rifleshooter.com’s Editor, explained his test procedure:
“I gathered four different types of factory Federal 224 Valkyrie ammunition, the 90gr Sierra MatchKing (SMK), 90gr Fusion soft point (SP) (referred to a Fusion MSR), 75gr Total Metal Jacket (TMJ) and 60gr Nosler Ballistic Tip Varmint (NBT). After a brief barrel break in and zero, I fired 5 rounds of each cartridge at each barrel length (except the 75 TMJ, I fired 4 rounds at each barrel length due to limited resources). I recorded the average muzzle velocity and standard deviation for each ammunition and barrel length combination and cut the barrel back 1 inch and repeated the process. I recorded barrel lengths from 28″ to 16.5″ (I try to save these barrels as finished 16″ tubes so they don’t go to waste).”
The Heavy Bullet 90gr Ammo Lost about 21 FPS per Inch
How did the test turn out? You’ll find all the results summarized in helpful tables with inch-by-inch velocity and SD numbers. For the two, 90gr ammo samples, results were similar. The 90gr SMK ammo started at 2782 fps (28″), finishing at 2541 fps (16.5″). That’s a loss of 241 fps, or 20.96 fps average per inch of length. The ammo loaded with 90gr Fusion SPs started at 2797 fps (28″) and ended at 2561 fps (16.5″), a drop of 236 fps. That’s 20.5 fps loss per inch. NOTE: Ambient temperature during the test was 45° F. You could expect the overall velocities to be a bit higher during hotter summer months.
With a the smaller bullets, the effect was even more dramatic. As you’d expect they started out faster. The ammo with 60gr Nosler Ballistic Tips (NBT), a good choice for varminters, started at 3395 fps (28″), and declined to 3065 fps (16.5), a total velocity drop of 330 fps. Average velocity loss was 28.7 fps per inch of barrel length. Rifleshooter.com also tested Federal 75gr TMJ ammo.
About the .224 Valkyrie Cartridge
The new .224 Valkyrie was introduced late last year as a Hot Rod cartridge that will work in AR15s. Designed to rival the .22 Nosler while still running well in ARs, the new .224 Valkyrie offers excellent long-range performance when loaded with modern, high-BC bullets. We expect some bolt-action PRS shooters might adopt the .224 Valkyrie. Why? Reduced recoil. With the 90gr SMK, the .224 Valkyrie offers ballistics similar to the 6.5 Creedmoor but with significantly less felt recoil. Check out this chart from Federal showing comparative recoil levels:
.224 Valkyrie vs. .22-250 Remington
The Social Regressive explains: “There are two key reasons why the .224 Valkyrie is unique and desirable. First, it is specifically designed to fit the limitations of the AR-15 platform. It does so even when loaded with gigantic bullets, like the 90-grain SMK that Federal announced. The .22-250 Rem is too long and too fat to work in the AR-15 platform; it needs an AR-10 bolt and magazine.”
The new .224 Valkyrie is basically a 6.8 SPC case necked down to .22-caliber. You can use your existing AR15 lower, but you will need a dedicated .224-Valkyrie upper, or at the minimum a new barrel, modified bolt with proper bolt face, and 6.8-compliant mags.

Product Tip from EdLongrange. We welcome reader submissions.
This barrel’s shoulder was 0.025″ off the action because Red Locktite had been used on the threads.
Gunsmith Thomas ‘Speedy’ Gonzales offered this interesting report about how NOT to headspace a barrel. Hopefully you never discover something like this…
“A good friend and customer sent this rig in for repair after FedEx damaged the rifle during inbound transport from another smith. After repairing the stock and rebedding it, I decided to re-polish the barrel to make the repair perfect. Well this just added insult to injury as the barrel did not want to come off. After a few choice words, the barrel finally broke free only to reveal something very disturbing. It seems the barrel had been ‘headspaced’ by using RED Loctite to hold it in place.” [Editor: That’s definitely NOT how barrels should be fitted.]
Speedy was not happy: “I hope the smith that did this sees the photos and realized what jeopardy he put my customer in or anyone who shot the rifle for that matter. When cleaned up, the shoulder on the barrel was over 0.0250″ (25 thousandths) away from the face of the receiver.” [Editor: That’s a lot in this business]. Check out the images below to see how much the barrel rotated further inward when cleaned up. The barrel spun in nearly another eighth-turn or more. Not good.

In the digital archives of Shooting Sports USA, we’ve found some great features that deserve a second look. A few years back, Shooting Sports USA published Sights, Wind and Mirage, an outstanding article that explains how to judge wind speed/direction and adjust your sights accordingly. Authored by highly respected shooter Ernest (Ernie) Vande Zande, this article is a definite “must-read” for all competitive rifle shooters — even those who shoot with a scope rather than irons. Vande Zande’s discussion of mirage alone makes the article well worth reading. Highly recommended.
Invaluable Insights from a World-Class Shooter
The article covers a wide variety of topics including Wind Reading, Mirage, Effects of Sight Canting, Quadrant Shooting, and Sight Adjustment Sequencing. Vande Zande offers many jewels of insight from his decades of experience shooting and coaching in top level tournaments. U.S. Shooting Team Leader at the 1996 Olympics, Vande Zande has set more than 200 records in National and International competition. He was the Smallbore Rifle Prone Champion at Camp Perry in 1980. An International Distinguished shooter, Ernie has been on nine Dewar teams and he was a member of the USAR Shooting Team from 1982.

The 2020 NRA Annual Meetings & Exhibits will be held in Nashville, Tennessee this year. This should be a very popular event, given Nashville’s rich heritage as “Music City”. The NRA expects big crowds this year: “With exhibitors inside and outside the Music City Center in downtown Nashville, there is something for the whole family! Spend the day exploring products from every major firearm company in the country, book the hunt of a lifetime in our outfitter section, and view priceless collections of firearms in our gun collector area. You’ll also see knives, shooting accessories, hunting gear, and much more.” The event runs April 16-19, kicking off with the NRA Auction and BBQ on the evening of the 16th.
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 major F-Class 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):
Note — this list, now in its 20th 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:
Many of our readers use AR-type rifles for Service Rifle matches, varmint hunting, 3-Gun competition, or defensive use. AR-platform rifles can be configured in a multitude of ways to suit the application. But if you plan to put together your own purpose-built AR rifle, how do you get started?
For AR Do-It-Yourselfers, we suggest reading Glen Zedicker’s book, the Competitive AR-15 Builders Guide. Following on Zedicker’s The Competitive AR15: Ultimate Technical Guide, the Builders Guide provides step-by-step instructions that will help non-professional “home builders” assemble a competitive match or varmint rifle. This book isn’t for everyone — you need some basic gun assembly experience and an aptitude for tools. But the AR-15 Builders’ Guide provides a complete list of the tools you’ll need for the job, and Zedicker outlines all the procedures to build an AR-15 from start to finish.
One of our Forum members who purchased the AR-15 Builders Guide confirms it is a great resource: “Much like any of the books Mr. Zediker puts out this one is well thought-out and is a no nonsense approach to AR building. I can not stress how helpful this book is from beginner to expert level.”
Along with assembly methods, this book covers parts selection and preparation, not just hammers and pins. Creedmoor Sports explains: “Knowing how to get what you want, and be happy with the result, is truly the focus of this book. Doing it yourself gives you a huge advantage. The build will honestly have been done right, and you’ll know it! Little problems will have been fixed, function and performance enhancements will have been made, and the result is you’ll have a custom-grade rifle without paying custom-builder prices.” Other good resources for AR projects is Gunsmithing the AR: The Bench Manual, and the Building Your AR from Scratch DVD.
Whidden Gunworks has the long-awaited Barnard SMS action. This impressive new 3-lug Rem-footprint action is NOT just another Remington 700 clone, though it fits Rem-inletted stocks and chassis systems. The Barnard SMS is a high-quality, custom-grade action. With the 3-lug design, bolt handle lift is shorter and quicker than its top competitors. And the excellent trigger timing of the SMS provides a smooth, glass-like operation.
New Zealand-crafted Barnard actions, such as the venerable Model P, have been highly coveted in the competitive long range community based on their high quality, ease of maintenance, and superb performance. Here in the USA, customers have asked for the same Barnard quality in a format that allows the use of Rem 700-configured stocks, triggers, magazines, and other accessories. This new SMS action can be used for long-range competition, PRS, benchrest, silhouette, hunting — any application where Rem 700-type actions are popular.
This new SMS action works with the Rem 700-family accessories which are readily available on the market. No adapters or conversion blocks are necessary for this action. The Barnard SMS is a true drop-in fit with Rem 700-inletted stocks and chassis systems. Likewise magazines and triggers for the Remington 700 footprint fit and work 100% with the new Barnard SMS.
Whidden Gunworks states: “Sportsmen all over the world will agree to the unequaled and superb quality of Barnard actions. The internal parts are simple and robust. Disassembly and maintenance can be easily done in the field if needed quickly, returning your firearm back into service. Quality material and proper heat-treating methods ensure strength and longevity for a lifetime of use. The new Barnard SMS is a great new offering.

In a recent Forum thread, one member asked for recommendations for a factory rifle with a good action and trigger, under $600.00. Many respondents recommended a Tikka T3 (or newer T3X), and we concur. These won’t run with a $2500 custom, but for a hunting or varminting rig, they offer good bang for the buck with a very nice action. The last Tikka T3 we tried, a .308 Win with 24″ barrel, easily shot sub-MOA groups with factory ammo.
The original Tikka T3 and newer T3x actions are rigid, robust, and well-crafted. They cycle smoothly and have a short 75° bolt lift. The bolt features a Sako-style extractor, with angled-leading-edge bolt lugs for smooth lock-up. These T3/T3x rifles offer smooth-running actions, easy sub-MOA accuracy with good ammo, crisp triggers, and ultra-reliable detachable box magazines. The Tupperware stocks aren’t super-rigid, but they are comfortable and easy to handle.
If you are looking for a hunting rifle, the Tikka T3/T3x is a smart choice, offering good performance for the price (which starts at $569.00 for the T3X Lite version). The current T3x series is offered in a wide selection of chamberings, from .204 Ruger up to the large magnums.
We were impressed with the new Tikka T3x UPR rifle we saw at SHOT Show 2020 We liked the stock very much, and thought this was a very versatile gun that could be used for target shooting off bipod, hunting, even PRS, given its detachable magazine. The stock is very ergonomic and feels good. Tikka states the UPR’s stock “features an extra layer of carbon fiber mixed with fiberglass for increased rigidity and accuracy.”

Tikka T3 Upgrades — Barrels, Stocks, and Chassis Systems
Once you acquire a Tikka T3 there are many interesting upgrades available. First, you can improve accuracy and consistency with a pre-fit barrel from Criterion. There are also many chassis systems that fit Tikkas. In fact you can even get an Eliseo Chassis so you can shoot Palma matches F-TR competitions, or tactical/practical matches.
Criterion Pre-Fit Barrels for Tikka T3/T3x
We have always liked Tikka actions, and now there is a great re-barreling option for Tikka T3/T3x owners. Criterion Barrels Inc. (CBI), makers of “pre-fit” barrels for Savage, Remington, and Rem-clone actions, also crafts Tikka pre-fits. These pre-chambered barrels for Tikka T3 actions will be headspaced with a barrel nut, just like a Savage.

Tikka T3/T3x pre-fit barrels are sold through Solid Accuracy, a respected Texas-based outfit that sells high-end scopes, stocks, barrels and other rifle components. Price is $461-$485 with various contours and lengths available. Order HERE.
Competition Machine Chassis for Tikka T3
At SHOT Show, we saw some tactical shooters admiring the smooth Tikka T3 action and crisp trigger. They liked the action but they told us they wished they could get the T3 action in a configuration similar to the Ruger Precision Rifle. Well folks, there is a way to build a Tikka T3-based tactical/practical rig.
Gary Eliseo of Competition Machine offers a tubegun chassis for Tikka T3 actions in both Target and Tactical versions. The T3 kit is set up for AICS short action magazines. This is a “no gunsmithing” installation — no modifications to the action are required and the chassis kit works with the factory T3 trigger and safety. Along with the new Target and Tactical versions, a lower-cost Light-Weight Hunter T3 Chassis is also offered which accepts most AR-type buttstock assemblies.
Full Tactical Upgrade for Tikka T3
Tikkas are boring, nondescript hunting rifles right? Wrong. Check out this Tikka T3 tactical with “attitude”. For the British Shooting Show a while back, the folks at Osprey Rifles placed a Tikka T3 action into a modern modular chassis: “A standard factory Tikka T3 was fully Cerakoted and dropped into a Third Eye Tactical chassis stock which also had the Cerakote treatment.”
Click Photos to see full-screen version.
This T3 Chassis can be ordered through Osprey Rifles in the UK. The latest chassis stock system from Third Eye Tactical is currently available for both the Rem 700 short action and the Tikka T3.
