This .308 Win was purpose-built for PRS/NRL tactical competition. With all the focus on the 6.5 Creedmoor, 6mm Creedmoor, and smaller 6mm cartridges, it’s easy to forget that the PRS has a Tactical Division limited to .223 Rem and .308 Winchester. This gun was built by Jim See of Elite Accuracy LLC to compete in that class, which also has a .308 bullet-weight limit of 178 grains, and a velocity limit of 2800 fps.
With those restrictions, this is truly a Tactical Tack-Driver, as you can see from those 100-yard targets in the photo above. This gun seems to shot great with everything Jim has tried. He started the season with Sierra 168gr Tipped MatchKings. Later he switched to 168gr Berger Hybrids. For both bullet types he uses Varget powder, CCI 200 primers, and Lapua large primer .308 Win brass. His current match load runs about 2765 FPS, with impressive 5-7 FPS standard deviation. The gun hammers — even at very long range. Jim told us: “That soda bottle was shot at one mile with a 168gr Berger Hybrid on top of Varget.” Jim says the 1:9″ twist rate helps deliver a “clean sub-sonic transition” at that distance.
With its heavy-contour barrel, the gun weighs in at a hefty 22 pounds, including optics and bipod. If you like this rig, Jim See can build you one just like it, or with the chambering of your choice. Visit EliteAccuracy.com to learn more about Jim’s gunsmithing services.
This rig features a RBRP Impact Precision 737 Action which was designed specifically for PRS-type tactical applications. This action features an integral lug, and built-in +20 MOA Picatinny rail. Both receiver and bolt are black-nitrided for slickness and durability. Jim loves the action: “It is really slick operating. It functions really well and doesn’t get gummed up with dirt or grit, so it has caught on for the PRS/NRL game. This action has won a major share of 2-day PRS matches this past season.”
Barrel Is a Resurrected .300 WSM
This rifle has one “resurrected” component — the barrel. The 1.25″ straight-contour, 1:9″-twist Brux was originally chambered as a .300 WSM finished at 30 inches. As acquired from Pat Scully, the barrel had 1200 WSM rounds through it. See then re-chambered the Brux as a .308 Winchester, finished it at 25 inches, and attached a 4-baffle side-discharge muzzle brake. Jim says the brake really helps control muzzle lift.

Running the Rifle in Competition
Jim says this rifle performed well right out of the gate: “For about three years I wanted to shoot Tactical division and in 2018 it happened to work out. I decided it was a good year to test the .308 Win waters and see how the .308 could stack up competitively against the Open Class rifles.
I dug around the shop and found an 11-twist 30″ M-24 from an old F-class rifle and chopped it down to 23″ and fit it to an Impact action. [EDITOR: This barrel was later replaced with the 1:9″ Brux finished at 25 inches.] I had not received my 168gr Berger Hybrids yet so I ran the Sierra 168gr Tipped MatchKings in the first couple matches of the season. Those SMKs were used for the target and chrono pictures here.
The first spring match was ‘The Battle for Breakneck’ in Nebraska. This is a true field match with mostly prone stages with a few natural rock barricades thrown in for positional shooting. The yardages went out to a little over 1400 yards. I went in feeling good and shot very well in the windy conditions, hitting targets out to 1350 yards. I finished with a score of around 105 out of 135 points. The Open Class winner shot a 117 score I believe. I ended up being First-Place Tactical and 16th overall in a field of 100 shooters.”
Consistency and Preparation — Keys to Success in PRS/NRL Competition
Through his Elite Accuracy LLC company, Jim offers skills training for tactical shooters. When we asked Jim if he had any advice for PRS/NRL competitors, Jim replied: “Consistency is what will continually put you at the top of a match. In addition, your gear needs to be prepared (100% sorted out) and your mind needs to be prepared and ready. Don’t let your mind get in your own way. Mental preparation and confidence will be key to success.”
Competitor Warren Dean has employed a hex-end barrel to permit rapid barrel changes on his F-Class rig. Warren wrote: “I have been running what is commonly known as a switch barrel on my F-T/R rifle. Basically it allows for removal and reinstallation of the barrel with basic hand tools and with no, or very minimal, shift in zero. The two gunsmiths that I trust, Larry Racine and John Whidden, both told me that the switch barrel system would return to a very close zero with no problems. [This system] can be a great benefit to the traveling shooter and a money-saver for the shooter wanting to shoot different calibers on the same chassis.” READ Dean Switch-Barrel Report.
Larry Racine Barrel Sytem
Larry Racine is a respected gunsmith based in New Hampshire. He is also a two-time member of the U.S. Palma Team, and a five-time New Hampshire State Highpower rifle champion. Larry, who runs LPR Gunsmithing, has developed a brilliantly simple means of switching rifle barrels with an ordinary spanner or open-end wrench. With this set-up you can switch barrels in the field in seconds without the need for a barrel vise.
For most barrels, Larry mills a hex with six flats on the end of the barrel. This allows a shooter to change barrels quickly at home or on the line with a simple box-head wrench or a socket wrench. Larry says: “You don’t even have to take the barreled action out of the gun. Just set the buttstock on the ground, between your feet, put a wrench on it, hit it with the palm of your hand — and off comes the barrel.” For barrels fitted with a muzzle brake, Larry has a slightly different system. He mills two flats behind the brake so you can use an open-end wrench to do the job.
With either a hex on the end, or two flats for a brake-equipped rifle, the system works with any medium- to heavy-contour barrel with a muzzle-diameter of at least 0.700″. This will even work for high-power rigs using clamp-on sights or bloop tubes. Larry explains: “A lot of us here in New England use clamp-on front sights. The barrel will be turned to 0.750 for the sight, with the hex on the end. A bloop tube can go right over the end, no problem.”
Larry has used this system over the past few years to win a number of matches. In one 600-yard 3 by 20 prone match, Larry used three different barrels, with three different chamberings, on the same Savage rifle. Larry changed the barrels on the line.
Larry was able to do this because the system has little to no loss of zero from one installation of a given barrel to the next installation of that barrel. This lets the shooter start the match with confidence that the first sighter will be on paper. Larry reports that the simple system works great: “To date we have used this system on Savage, Remington, Winchester, RPA, and Nesika actions.”
Varminters Take Note — This Is Great in the Field
If you are a varminter shooting hundreds of rounds in a day, consider this system. We know some guys who bring 3 or 4 rifles into the field because their barrels get hot during long days of prarie dog hunting. With this smart system, you can easily swap barrels in a couple minutes. And no special equipment or barrel vises are required.
Modifying Barrels is Affordable
Racine’s system for rapid barrel removal/changing is very affordable. If Larry does the chamber work on your barrel he charges $45.00 extra to mill a hex or two flats on your barrel. The customer chooses the configuration.
If you only want the hex or flats done, Larry may charge a higher fee — call for current rates. Note this can also work for barrels with muzzle brakes or threads for suppressors. For more info, visit LPRGunsmith.com or call Larry at (603) 357-0055.
Peterson now offers 6mm Creedmoor, 6.5 Creedmoor, .308 Win, and .300 Norma Mag loaded ammo.
Peterson Cartridge, a leading USA-based cartridge brass maker, is expanding its product line. Peterson recently announced that it will produce loaded ammunition. This new Peterson Precision Ammunition, of course, features Peterson brass, along with bullets from Berger, Hornady, and Sierra. There will be four (4) ammo types initially: 6mm Creedmoor, 6.5 Creedmoor, .308 Win Match, and .300 Norma Mag. (NOTE: We’ve also seen a photo labeled “7mm” so perhaps a .284 Win is on its way, or maybe a 7mm SAUM?)
The ammo is reasonably priced. For example, the 6.5 Creedmoor ammo costs $35.00 for 20 cartridges, or $1.75 per round. Here are the product specs for the four cartridge types currently offered. You can access Full DROP CHARTS by clicking each photo below.
This ammo is all assembled in the USA, using Peterson brass and American components: “The entire manufacturing process, from creating the brass to loading the full rounds of precision ammunition takes place in our manufacturing facility located in Warrendale, Pennsylvania. Peterson Cartridge is dedicated to producing the best American-Made ammunition possible.”

Peterson ammo tip from EdLongrange. We welcome reader submissions.
Do you shoot a Springfield M1A rifle chambered for the .308 Win/7.62×51? Or maybe you have a rugged, semi-auto FN-FAL in 7.62×51 NATO? Are you looking for very strong, durable brass you can shoot in these semi-auto battle rifles, without breaking the bank?
Photo of 2009 M1A Match at Camp Perry. Shooter is Nick Till, 2007 Service Rifle Champion.
Semi-autos such as the M1A are tough on brass. You want brass that isn’t too costly, but at the same time is very strong and durable. For decades, USA-made Lake City brass have been a solid choice for 7.62×51 semis, and now you can get quality, unfired 7.62×51 Lake City brass for just $49.99 for 250 cases at Midsouth. That’s just $0.20 (twenty cents) per case! That’s a fourth what you’ll pay for premium, virgin .308 Winchester brass. These cases are never-fired brass, with CCI #34 primers seated in crimped, military-style primer pockets.
This 7.62×51 Lake City brass comes from disassembled “pull-down” ammunition. It has NOT been fired, but it has been previously assembled. So, there may be some cosmetic issues with the brass. Note that these are primed cases. If you choose to neck-size or FL-size the brass before loading for the first time, REMOVE the decapping rod in your sizing die. This brass has LIVE PRIMERS!! Do NOT use a die with a decapping rod for the first loading of this brass. Got that guys? This is important!!
We have shot FN-FAL-type rifles built on DS Arms semi-auto lowers with European uppers. Those beasts were tough on brass, so we relied on Lake City brass when available. If you have a FN-FAL or STG-58, you should give this Lake City primed, pull-down brass a try. (Federal Gold Medal Match ammo shot great in our DSA/STG-58 but the brass was toast after a few firings).
Three factory ammo types shot 0.53″, 0.55″, and 0.57″ respectively. That’s impressive.
Chassis rifles are hugely popular for PRS/NRL practical rifle competition. There are many good options for Production Class. You may not know that Weatherby, a company that built its reputation on hunting rifles, offers a great-shooting chassis rifle for PRS comps and other tactical disciplines.
Called the Vanguard® Modular Chassis (VMC), this rig has shown remarkable accuracy. Vanguard’s VMC features a Modular Driven Technologies (MDT) aluminum stock, Luth AR MBA-1 buttstock, and 22″ heavy barrel. The Weatherby Vanguard action is fitted with an adjustable 2-stage trigger. Priced at $1519.00 MSRP, this rifle can be campaigned in the PRS “Production Class”, which limits complete rifles to $2000.00 without optics. The rifle is offered in three chamberings: .223 Rem, 6.5 Creedmoor, and .308 Winchester.
Weatherby says its Vanguard Modular Chassis tactical rifle is very accurate. To back that claim, Weatherby offers a SUB-MOA accuracy guarantee — Weatherby guarantees the rifle will shoot .99” or smaller 3-shot groups at 100 yards when used with Weatherby® factory or premium ammunition.
Near Half-MOA Accuracy with Factory Ammo (5-Shot Groups)
It turns out Weatherby’s accuracy claims are conservative. This tactical rifle is closer to a half-MOA rig than a 1-MOA gun. American Rifleman tested a .308 Win version of this rifle and recorded really stellar accuracy — close to half-MOA. What’s more, this rifle is not fussy — with a 1:10″-twist barrel it proved very accurate with six types of factory ammo, with three of types registering 0.57″ or better.
The rifle delivered near-half-inch 5-shot groups with two types of Hornady ammo along with Black Hills 168gr. The worst group of six ammo types tested, Black Hills 175gr, was 0.76″, still very impressive for factory fodder. With good hand-loads this gun could go well under half-MOA (for five shots).
Vanguard Modular Chassis FIVE-SHOT Factory Ammo Test Groups:
0.53 inches | Hornady 168gr Match BTHP (2718 fps)
0.55 inches | Hornady 155gr Steel Match (2612 fps)
0.57 inches | Black Hills 168gr BTHP (2608 fps)
0.66 inches | Federal Premium 168gr MatchKing BTHP (2659 fps)
0.70 inches | Hornady 155gr American Gunner (2697 fps)
0.76 inches | Black Hills 175gr BTHP (2603 fps)
NOTE: Group sizes are for 5-shot groups shot from bench at 100 yards with Caldwell pedestal rest and rear sandbag. Pentax Lightseeker 6-24x50mm scope. Velocities in FPS from PACT Chronograph.
The accuracy testing was done by gunwriter Mike Detty, who notes: “My single best group was fired with Hornady’s Match 168-gr. BTHP ammunition. Five shots measured just slightly more than a half-inch. Hornady’s 155-gr. Steel Match ammo wasn’t far behind with a group of .55″. Also accounting for the small groups is the VMC’s wonderful trigger. It is a two-stage affair and the first stage has about 3/8” take up with about a pound of pressure until it reaches the second stage where another 1 ¾ lbs. was required to break the shot.”
Vanguard Modular Chassis FEATURES:
Action with Fully Enclosed Bolt Sleeve, Integral Recoil Lug
CNC-machined, hard-anodized, 6061 aluminum chassis
Fully adjustable LUTH-AR MBA-1 buttstock
Adjustable 2-stage trigger with 3-Position Safety
PRS Production Class Cost Limits
Production Division combined rifle and scope MSRP as listed on the company’s website shall not exceed $3,000 USD, the rifle shall not exceed $2,000 USD and the optic not exceed $2,000 USD. [Editor: For example, you could have a $2,000 rifle with a $1000.00 scope or vice-versa. The total system cannot exceed $3000. Rifle alone cannot exceed $2000.00 retail sale price.]
Production Division rifles are not permitted to be altered or improved in any way from the original factory configuration.
First there was F-Class, and now there will be E-Class, the “E” standing for “Economy”. The NRA Competitive Shooting Division has just approved a new form of rifle competition starting in 2020: E-Class. Unlike F-Class, E-Class will have tight rifle and gear cost controls. This is a clear response to rising F-Class costs, which have spiraled out of control. The first major E-Class National event will be a preview match held this summer at Camp Atterbury in Indiana.
The NRA’s sanctioning of E-Class competition makes sense. Let’s face it, top-level F-Class competition, both F-TR and F-Open, has become just too expensive. A modern F-Open rifle capable of winning a championship can now cost $9000.00 or more, including rest, premium trigger, and optics. Under the NRA’s new E-Class Rules, rifles can cost no more than $2000.00 total, including optics and rest (E-Open) or bipod (E-TR). In addition, new E-Class rules will recognize a special division, called E-Factory, that is limited to factory rifles, such as the Savage F-Class rig and Ruger Precision Rifle. Factory Class will be restricted to .223 Remington to keep costs down.
E-Class Factory Division
Complete Rifle RPR: $1200
Barrel: Included
Stock: Included
Optics: $400
Trigger: Included
Bipod: $100
Rear Bag: $50 Total: $1750.00
Under the new E-Class rules, TOTAL Cost for an E-Open or E-TR Rifle is limited to $2000.00, including optics, front rest or bipod, and rear bag. There are specific gear limits. Scope maximum is $500.00. Front rest or bipod is limited to $200.00. In the chart above you see how an E-Open rifle could be built for under $1800 with a factory action (such as Howa or Savage) and a $400.00 optic. In the third column we’ve priced out an E-Factory rifle, based on a Ruger Precision Rifle, at $1750.00.
A top-of-the-line F-Open set-up like this can cost more than $8000.00 with custom stock, high-end optic, and coax front rest. All new E-Class rifles must cost less than $2000 including rests and scope.
Either way these E-Class rigs cost ONE-FIFTH of the Top-of-the-line $8750.00 F-Open Rig. That’s a huge savings, that will allow more shooters to enjoy competitive shooting. E-Class combines the fun challenge of the F-Class course of fire, with a vastly lower investment. With the rising costs of taxes, food, fuel, and everything else, it’s high time we get serious about the money we throw away on competition rifles. We know the wives will approve!
Keeping on Lid on Expenses
In the Wings — Controls on Ammo Costs as Well
Shooters know that the price of the rifle, optics, and rests is only part of the cost equation. The price of ammunition is also significant. Currently, in F-Open, competitors can easily pay $1.00 per round just for the expendables — bullets, powder, and primer. Add in the cost of premium .284 Win brass and the cost per shot goes up significantly. One competitor lamented “Shooting a match these days really empties your wallet. I cringe every time I pull the trigger, knowing what it costs.”
Therefore, the NRA is considering E-Class ammo restrictions. Starting in 2021, E-Factory class competitors would be required to shoot recycled bulk brass and blem bullets. Bulk Lake City 5.56 brass will be offered by ARMorAlly.com, and blem bullets will be offered by Midsouth Shooters Supply. Purists may complain about using surplus brass, but it only costs $93 for 500 cases! That’s a huge savings.
The Final Step — Claiming Rules for E-Class
As in every competitive endeavor, there may be temptation to bend or even break the rules. Predictably, some E-Class competitors may try to substitute more expensive components, such as high-cost triggers, or modified actions. To prevent this, the NRA plans to impose claiming rules for E-Class matches. This means that any rifle that captures first or second place in a major match can be claimed by another competitor for the fee of $2000.00. This procedure may seem radical but it is used in other sports to ensure parity among the competitors. If a shooter wins with a “cheater” $5000.00 rifle, he can be forced to sell it to a competitor for $2000.00.
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.
Proud owner Dirk L. says: “This is my first build — never thought it would be a .308!”
Here’s a handsome F-TR rifle with a beautiful red stock that suits the holiday season. This ruby red beauty was a recent addition to the long-running Pride and Joy Rifle thread in our Shooters’ Forum. The rifle belongs to Forum member Dirk L. (aka “Pinkes”) who hails from South Africa. This is a .308 Win, with 30″ Bartlein barrel, and X-Max action. The stock is a custom composite with carbon fiber for strength and lightness. And yes this rifle shoots as good as it looks. Check out the impressive 5-shot groups below…
X-Max for Xmas — Impressive Metal-work
Along with that beautiful red stock, this F-TR rig has some very cool features, including a South African-crafted X-Max Action. The action designer Piet Welgemoed explains: “The X-Max action body is 17-4PH stainless steel pre-hardened to 44° Rockwell. Bolt and handle are one-piece stainless steel, nitrated to 55° Rockwell 0.2mm deep. Bolt is also fluted. Inside is the firing pin with washers (see below). The washer cuts the lock-time almost by half and also weighs less. The bolt-knob and bolt shroud are CNC aluminum. The action has very tight tolerances.” The complete action with +20 MOA rail and trigger weighs 1.475 kg (3.25 lbs).” Owner Dirk notes that the competition trigger, set at 3.0 ounces, is also Welgemoed’s design.
Wicked Accuracy with Bartlein Barrel, Varget, and 220gr SMKs
This gun has already proven to be a great shooter. Below are two FIVE-shot groups at 100 meters. The group on the left is in the low threes, with three of five shots essentially in one hole. Dirk loads Lapua .308 Palma brass and #2231 200gr Sierra Matchkings, seated 20 thousandths off the lands. The Varget powder and CCI primers drives the 200gr SMKs at 2620 fps.

Bullet: New 200gr SMK #2231 | Seating: 0.020″ Off | Velocity: 2620fps
Composite Stock — One of Three by Renier Mostert
And what about that beautiful red stock? The rifle’s owner told us: “This was one of three similar stocks built as a test run by Renier Mostert, a professional composite stock builder and former benchrest shooter from Pretoria, South Africa. Renier was approached by three friends, who were all looking for decent, custom-built FTR composite stocks. There were a number of stocks available to them (mostly imported), but [those] were either made of wood or aluminum. The requirements for the composite stock build was very specific. Aluminum V-Blocks for the actions were required. The stocks had to be light enough to carry some beefy barrels and optics without compromising rigidity and still be within the F-TR weight limit. The three friends supplied Renier with an imported wooden stock as their shape of choice. Although the shape was quite straight-forward, Renier made a few dimensional changes to features which were not symmetrically correct on the sample, and then built a mold from it.”
Renier uses several methods to craft composite stocks for various disciplines: F-Class, benchrest, competition rimfire, hunting, and tactical. For this build he chose to build a shell constructed of a well-planned mix of woven fiberglass cloth and bi-directionally woven carbon fiber with aerospace quality epoxy resin to reduce weight in some areas and increase stiffness in other areas. He used a wet lay-up process where the two halves gets laid up and joined together while still wet to form a complete, continuous shell. The closed mold gets cured under pressure in an oven for several hours at very specific temperatures. After curing, the shell is filled with a high-tech mix of lightweight filler and epoxy resin. The composition of the mix varies in different areas of the stock to facilitate more strength or reduced weight where applicable.
After the initial build, the aluminum hardware was installed. An adjustable cheek piece, Anschutz rail, and adjustable recoil pad mechanism were installed. The stocks were inletted by Renier, while the final fitting and bedding procedures were left for each customer’s gunsmith to complete. The stocks were light enough for the rifles to comfortably be within the F-TR weight limit. A barrel tuner was mounted on one of the rifles, and the rifle still made the F-TR Class weight limit, 8.25 kg (including bipod). The bipod shown in photos in the SEB Joy-Pod.
Paint — Candy Apple Red over Metallic Silver Base
After final gunsmithing, the stocks were returned to Renier Mostert for custom painting. The rifle featured in this article was done in Candy-Apple Red paint from DNA Paints (an Australian company). To get the desired effect, a metallic silver base coat was used, enhanced with a modest amount of medium coarse glitter, followed with multiple layers of candy until the correct shade was achieved. A high-quality automotive clear coat was used to finish off the paintwork.
Check out that 0.188″ group. Can you believe that was shot with factory .308 Win ammo? A couple seasons ago our friends at Criterion Barrels tested some .308 ammo from Creedmoor Sports. This was loaded with Lapua’s 175gr Scenar HPBT bullet. The results speak for themselves. Any time factory ammo can shoot inside quarter-MOA, that’s impressive. This ammo was used in a “Rem/Age” project rifle. That term refers to a Remington action rifle that has been re-barreled with a pre-fit Criterion barrel. The new barrel is secured with a Savage-style barrel nut. Hence the term “Rem/Age” or “Rem-Age”.
Criterion posted: “I think we may have a new favorite factory match load for the nitrided Rem/Age build.” Another reader added: “[Creedmoor’s] 175 Scenar .308 ammunition is top notch.” FYI, this group was shot on our load development target, which you can download for free from our Targets Page.
Why do Criterion barrels shoot so well? One reason is that Criterion’s barrel steel is carefully stress-relieved. In the photo below, Criterion Rack 1A (aka the “Coffin”) has been loaded with barrel blanks — made ready for the stress-relieving process.
Working with Pre-Fit Barrels
While they may require the purchase of some additional tools and a bit of a learning curve to install, using Rem/Age pre-fit barrels offer advantages over gunsmith chambering and barrel-fitting. In this video, 8541 Tactical explains how to install a Criterion 6.5 Creedmoor “pre-fit” barrel. You save money and time — you don’t have to wait for a gunsmith to chamber the barrel. While Criterion recommends that a competent gunsmith oversee the pre-fit installation, if you understand the use of go/no-go gauges and you have a barrel vise and action wrench set up to remove the original barrel, putting on a pre-fit barrel CAN be a DIY project. You don’t have to pack up your rifle to ship it off to a smith.
We are often asked “Can I get more velocity by switching primer types?” The answer is “maybe”. The important thing to know is that changing primer types can alter your load’s performance in many ways — velocity average, velocity variance (ES/SD), accuracy, and pressure. Because there are so many variables involved you can’t really predict whether one primer type is going to be better or worse than another. This will depend on your cartridge, your powder, your barrel, and even the mechanics of your firing pin system.
Interestingly, however, a shooter on another forum did a test with his .308 Win semi-auto. Using Hodgdon Varget powder and Sierra 155gr Palma MatchKing (item 2156) bullets, he found that Wolf Large Rifle primers gave slightly higher velocities than did CCI-BR2s. Interestingly, the amount of extra speed (provided by the Wolfs) increased as charge weight went up, though the middle value had the largest speed variance. The shooter observed: “The Wolf primers seemed to be obviously hotter and they had about the same or possibly better ES average.” See table:

You can’t extrapolate too much from the table above. This describes just one gun, one powder, and one bullet. Your Mileage May Vary (YMMV) as they say. However, this illustration does show that by substituting one component you may see significant changes. Provided it can be repeated in multiple chrono runs, an increase of 19 fps (with the 46.0 grain powder load) is meaningful. An extra 20 fps or so may yield a more optimal accuracy node or “sweet spot” that produces better groups. (Though faster is certainly NOT always better for accuracy — you have to test to find out.)
WARNING: When switching primers, you should exercise caution. More speed may be attractive, but you have to consider that the “speedier” primer choice may also produce more pressure. Therefore, you must carefully monitor pressure signs whenever changing ANY component in a load. Glen Zediker recommends decreasing your load ONE FULL GRAIN when changing to a different primer type, one that you haven’t used before.
