Federal District Court Dismisses Suit Against AR-15 Makers

Federal court case dismiss dismissal Primus Smith Wesson Ohio district U.S.

Chalk up a legal victory for the gun industry. The U.S. District Court (Southern District of Ohio) has dismissed, with prejudice, the Primus Group v. Smith & Wesson, et al lawsuit. The decision was delivered October 9, eliminating the plaintiff’s claims against several prominent AR-15 firearms manufacturers, including Smith & Wesson, Remington Arms Company, SIG Sauer, Sturm, Ruger & Company, Colt Manufacturing, and Armalite.

Federal court case dismiss dismissal Primus Smith Wesson Ohio district U.S.“This decision by the federal judge to dismiss with prejudice this frivolous case is pleasing, if not unexpected,” said Lawrence G. Keane, NSSF Senior Vice President of Government Relations and Public Affairs and General Counsel. “These are lawful and federally-regulated AR-15 modern sporting rifle manufacturers that make semiautomatic rifles for lawful purposes. The judge was absolutely correct to assert that the proper venue to establish public firearms policy is through the legislature and not the courts.”

Primus Group, LLC, is a small entity in Columbus, Ohio with a vague business model. The limited liability company filed suit after the tragic murders in El Paso and Dayton, Ohio. They claimed racketeering, intentional misrepresentation claims, and “a clear and present danger” of all American lives due to “assault weapons”. The modern sporting rifles manufactured and sold by the companies named as defendants are semi-automatic rifles, meaning one round is fired for each trigger pull.

The court found the plaintiffs had no standing to bring the case against the defendants. This decision rightfully asserts that those who purposefully and criminally misuse firearms are the ones who are responsible for those crimes. It further affirms that activist lawsuits to prompt judicial action are not the proper avenue to establish policy.

It’s deer-hunting season throughout the country. The chance to bag a Muley buck drew action-shooting ace Jessie Harrison out to Wyoming’s Bighorn Mountains region. Jessie, who is probably the best lady action pistol shooter on the planet, had a successful hunt with Big Horn Outfitters. Jessie, Shooting Team Captain for Taurus USA, really enjoyed getting out into the Wyoming wilderness. And she got her buck!

Oklahoma CMP Games Are Underway This Weekend

CMP Oklahoma Games

The Civilian Marksmanship Program (CMP) Oklahoma Games are happening this weekend at the Oklahoma City Gun Club. Events started on October 7th and run through Sunday the 13th with the final event — the popular Vintage Sniper Team Match. If you’re anywhere near OK City you might want to check out the action. There are Vintage Military Matches today, along with Rimfire Sporter competition and EIC pistol matches. The CMP’s Oklahoma Games are not just for seasoned competitors. There will be a Small Arms Firing School plus a New Shooter Clinic for those who have never fired in a CMP Games match.

CMP Games Oklahoma

Oklahoma Games Resources

Previously held in April, the CMP Oklahoma Games will feature the popular M1 Garand, M1 Carbine, Springfield, Vintage/Modern Military, Rimfire Sporter, and Vintage Sniper Rifle matches. Pistol matches, such as the As-Issued 1911, Military & Police Service Pistol and .22 Rimfire Pistol will also be held throughout the week. The CMP Cup Matches will again be held at this Travel Games event. This include two days of invididual competition, followed by a 4-Man Team Match, and EIC Service Rifle Match.

Electronic Targets Allow Faster Relays and No Pit Duty!
High Power competitions will be fired on CMP Targets, an electronic target system that plots shot placement in real time, and eliminates the need for pit duty — allowing quicker matches with less physical labor. Shot locations/scores appear on remote monitors placed at each shooting location.

CMP Oklahoma Games

Along with competitive matches, a rifle Small Arms Firing School (SAFS) was held. Both beginning and experienced marksmen were trained in the classroom and on the firing line, with the help of CMP staff and certified instructors. SAFS attendees learned rifle handling, shot technique and safety, followed by firing in an actual M16 EIC match.

CMP Oklahoma Games

VINTAGE SNIPER MATCH — Sunday October 13th
The last event of the 2019 Oklahoma Games is the Vintage Sniper Team Match. Competitors must use Korean War or earlier, as-issued military sniper rifles or replicas of those rifles. Optics must also be original issue or replica scopes from the same period. The CMP Games Rules lists the approved rifles and optics.

Camp Perry Vintage Sniper match Oklahoma

The course of fire is designed to reproduce the conditions under which skilled long-range military riflemen operated. Two riflemen work together as a team. During the match, each team member functions alternately as a shooter or a spotter. After one team member finishes firing, they switch roles and the other team member fires. Firing is done at distances of 300 and 600 yards from the prone position. Shooters may use either a sling or sand bag support, but not both. Wind doping is critical and firing must be done quickly; targets are exposed for each shot for only 20 seconds and then withdrawn for 20 seconds.

About the CMP Travel Games
The CMP Travel Games are regional competitions held in different corners of the country throughout the year, featuring exclusive CMP rifle and pistol outdoor events. A common part of the CMP schedule for the last decade, the Games are centered around recreation-oriented competition and educational activities that are designed to accommodate experienced marksmen as well as those just beginning the sport.

New Matchmaster Twin-Tube Powder Dispenser/Scale from RCBS

RCBS Matchmaster powder dispenser scale two tube match mode 0.04 grain chargemaster

RCBS has a new, high-speed, high-precision electronic powder scale/dispenser, the black-bodied RCBS Matchmaster. This new device features TWO dispensing tubes (high-speed and low-speed), plus optional software control via a smartphone App. It has a standard mode for fast dispensing and a “Match Mode” for ultra-precise dispensing to a claimed 0.04 grains. The Matchmaker has a nice LCD touchscreen and a unique anti-spill “Open Drain Alert” system.

How FAST is the Matchmaster? RCBS says, with the dual tubes, the Matchmaster can dispense a charge in under 20 seconds in Standard Mode.

How PRECISE is the Matchmaster? RCBS is claiming 0.04 grains precision. That’s four hundredths of a grain. This is close to one or two kernel accuracy with an extruded powder such as H4350. Watch Video:

How much will it COST? RCBS has not officially released an MSRP, but we’re told the list MSRP could be $899.00, with a “street price” around $770.00. Stay tuned for updated pricing information from vendors.

Is this a Force Restoration Scale? No. We have been told the RCBS Matchmaster does NOT employ Magnetic Force Restoration weighing technology.

Revolver Kaboom Provides Important Safety Lessons

Revolver kaboom wheelgun explosion mistake reloading powder safety

This shocking Revolver Kaboom resulted from “user error”. Our friends at Midsouth Shooters provided this cautionary tale, noting that you must ALWAYS be careful when hand-loading any ammo. Check your loads and don’t have multiple powder containers in your reloading area.

Revolver kaboom wheelgun explosion mistake reloading powder safety

“Ever wonder what happens when you don’t pay attention to detail? A word of advice from the reloader who brought this in — always double-check the load data.

Thankfully, the shooter was unharmed in the explosion. A live round we recovered from the remaining portions of the cylinder contained 12.8 grains of powder. The shooter had multiple powders on his bench and was unable to recall which one had been used while loading.” — Midsouth Shooters

Revolver kaboom wheelgun explosion mistake reloading powder safety

How to Avoid Kabooms

1. Never have more than one powder container open on your reloading bench at the same time — when you are finished with a powder, seal the bottle and put it away.

2. If there is already powder sitting in your dispenser, and you’re not 100% sure what it is — throw it out. We suggest, whenever you fill a powder hopper, put a piece of paper in the powder hopper with the name of the powder and the date.

3. When loading a new cartridge or when using a new powder, get load data from more than one source. Always load conservatively to start!

4. Always double-check your Load Data before starting the loading process.

5. In short handgun cases, bullet seating depth can make a BIG difference in pressure levels. Be sure to check your Cartridge OAL.

How to Succeed at Club Matches — Six Tips

During shooting season, there are probably 400 or more club “fun matches” conducted around the country. One of the good things about these club shoots is that you don’t have to spend a fortune on equipment to have fun. But we’ve seen that many club shooters handicap themselves with a few common equipment oversights or lack of attention to detail while reloading. Here are SIX TIPS that can help you avoid these common mistakes, and build more accurate ammo for your club matches.

Benchrest rear bag1. Align Front Rest and Rear Bags. We see many shooters whose rear bag is angled left or right relative to the bore axis. This can happen when you rush your set-up. But even if you set the gun up carefully, the rear bag can twist due to recoil or the way your arm contacts the bag. After every shot, make sure your rear bag is aligned properly (this is especially important for bag squeezers who may actually pull the bag out of alignment as they squeeze).

Forum member ArtB adds: “To align my front rest and rear bag with the target, I use an old golf club shaft. I run it from my front rest stop through a line that crosses over my speed screw and into the slot between the two ears. I stand behind that set-up and make sure I see a straight line pointing at the target. I also tape a spot on the  golf shaft that indicates how far the back end of the rear bag should be placed from the front rest stop. If you don’t have a golf shaft, use a wood dowel.

2. Avoid Contact Interference. We see three common kinds of contact or mechanical interference that can really hurt accuracy. First, if your stock has front and/or rear sling swivels make sure these do NOT contact the front or rear bags at any point of the gun’s travel. When a sling swivel digs into the front bag that can cause a shot to pop high or low. To avoid this, reposition the rifle so the swivels don’t contact the bags or simply remove the swivels before your match. Second, watch out for the rear of the stock grip area. Make sure this is not resting on the bag as you fire and that it can’t come back to contact the bag during recoil. That lip or edge at the bottom of the grip can cause problems when it contacts the rear bag. Third, watch out for the stud or arm on the front rest that limits forward stock travel. With some rests this is high enough that it can actually contact the barrel. We encountered one shooter recently who was complaining about “vertical flyers” during his match. It turns out his barrel was actually hitting the front stop! With most front rests you can either lower the stop or twist the arm to the left or right so it won’t contact the barrel.

3. Weigh Your Charges — Every One. This may sound obvious, but many folks still rely on a powder measure. Yes we know that most short-range BR shooters throw their charges without weighing, but if you’re going to pre-load for a club match there is no reason NOT to weigh your charges. You may be surprised at how inconsistent your powder measure actually is. One of our testers was recently throwing H4198 charges from a Harrell’s measure for his 30BR. Each charge was then weighed twice with a Denver Instrument lab scale. Our tester found that thrown charges varied by up to 0.7 grains! And that’s with a premium measure.

4. Measure Your Loaded Ammo — After Bullet Seating. Even if you’ve checked your brass and bullets prior to assembling your ammo, we recommend that you weigh your loaded rounds and measure them from base of case to bullet ogive using a comparator. If you find a round that is “way off” in weight or more than .005″ off your intended base to ogive length, set it aside and use that round for a fouler. (Note: if the weight is off by more than 6 or 7 grains you may want to disassemble the round and check your powder charge.) With premium, pre-sorted bullets, we’ve found that we can keep 95% of loaded rounds within a range of .002″, measuring from base (of case) to ogive. Now, with some lots of bullets, you just can’t keep things within .002″, but you should still measure each loaded match round to ensure you don’t have some cases that are way too short or way too long.

Scope Ring5. Check Your Fasteners. Before a match you need to double-check your scope rings or iron sight mounts to ensure everything is tight. Likewise, you should check the tension on the screws/bolts that hold the action in place. Even on a low-recoiling rimfire rifle, action screws or scope rings can come loose during normal firing.

6. Make a Checklist and Pack the Night Before. Ever drive 50 miles to a match then discover you have the wrong ammo or that you forgot your bolt? Well, mistakes like that happen to the best of us. You can avoid these oversights (and reduce stress at matches) by making a checklist of all the stuff you need. Organize your firearms, range kit, ammo box, and shooting accessories the night before the match. And, like a good Boy Scout, “be prepared”. Bring a jacket and hat if it might be cold. If you have windflags, bring them (even if you’re not sure the rules allow them). Bring spare batteries, and it’s wise to bring a spare rifle and ammo for it. If you have just one gun, a simple mechanical breakdown (such as a broken firing pin) can ruin your whole weekend.

Walmart Halts Sales of .223 Rem and Handgun Ammunition

Walmart ammo ammunition ban stop selling AR15 rifle shotgun

Walmart is yielding to anti-gun forces one step at a time. First the national retail chain stopped selling handguns in 1993. Next in 2015, Walmart stopped selling “black rifles” — AR-15 platform firearms. Then in 2018 Walmart raised the age for gun purchases from 18 to 21. And the latest restrictions involve ammunition. Walmart announced it would not longer sell ANY pistol ammunition. And Walmart now won’t sell .223 Rem (5.56×45) ammunition commonly used in ARs and “modern sporting rifles”. What comes next? If a criminal uses a shotgun in a multiple-death incident, will Walmart stop selling shotguns?

1993 — Walmart halts sales of all handguns.
2015 — Walmart halts sales of AR-15 type rifles.
2018 — Walmart raises minimum age for firearm purchase from 18 to 21 years.
2019 — Walmart halts sales of all pistol ammunition.
2019 — Walmart halts sales of all .223 Rem (5.56×45) ammunition.

Walmart Expands Its Anti-Gun Agenda

Article based on Report by Midsouth Shooters Blog

Walmart has been steadily rolling back its support of the Second Amendment since 1993 when it stopped the sale of all handguns in every state except Alaska. Then, in 2015 it ended the sale of AR-15 style MSR rifles, and any toy or airgun resembling any “military-style rifle used in mass shootings”. Last year, Walmart raised the minimum age for gun purchases from 18 to 21, two weeks after the Parkland, Florida school shooting. And Walmart rolled out another set of restrictions after the recent shooting at a Walmart Super Center in El Paso, Texas.

“Walmart may not sell the ammo you need, and more companies beholden to the pressure of the vocal minority may follow suit. Effectively, Walmart has been bullied into kowtowing to the social justice warriors, and woke-ninjas in the vocal minority.” — Midsouth Blog

In a memo to employees, Walmart CEO, Doug McMillon, stated: “After selling through our current inventory commitments, we will discontinue sales of short-barrel rifle ammunition such as the .223 caliber and 5.56 caliber that, while commonly used in some hunting rifles, can also be used in large capacity clips on military-style weapons.”

Walmart has also stated that it will no longer sell handgun ammo. McMillon previously said Walmart was responsible for 2% of firearm sales in the U.S. and 20% of ammunition sales. Walmart expects its share of ammunition sales to drop to between 6% and 9% as a result of the newly-announced changes. The company will continue to sell shotguns and rifles [But for how long? — Editor].

“In a complex situation lacking a simple solution, we are trying to take constructive steps to reduce the risk that events like these will happen again,” McMillon said in a memo. “The status quo is unacceptable.” In this 2015 video, McMillon explained the decision to stop selling AR-platform rifles.

Walmart ammo ammunition ban stop selling AR15 rifle shotgun

Changes to Walmart Gun Carry Policies
Another rider on the new Walmart policy affects customers who open-carry in their stores. If shoppers openly carry guns into Walmart stores going forward, store managers may ask the shopper to leave and safely secure their gun in their vehicle before returning to the store. “The policies will vary by location, however, and shoppers who are openly carrying guns may not always be asked to leave the store,” a Walmart spokesman said.

“As long as a Hornady is at Hornady, we will never sell direct to Walmart. They are no friend of the industry.” — Jason Hornady, 2007

Walmart CEO Calls for More Gun Control
“We encourage our nation’s leaders to move forward and strengthen background checks and to remove weapons from those who have been determined to pose an imminent danger,” McMillon said. “We do not sell military-style rifles, and we believe the re-authorization of the Assault Weapons Ban should be debated to determine its effectiveness.”

Commentary from Midsouth Shooters
Walmart may not sell the ammo you need, and more companies beholden to the pressure of the vocal minority may follow suit. Midsouth will continue to sell the ammunition and reloading supplies you need, regardless. Our Second Amendment right is a sacred right, and for you to protect your family with the tools available, you need access to fairly priced ammunition and firearms.

Midsouth Shooters supply

Midsouth Shooters was founded on the tenants of honesty, family, and fairness, rooted in American and God. For a company, or organization, to be swayed by knee-jerk reactions sets a precedent of allowing the mob to dictate overreaching policies which put many in harms way. Effectively, Walmart has been bullied into kowtowing to the social justice warriors, and woke-ninjas in the vocal minority.”

New High-BC 85.5 grain .224-Caliber Bullet from Berger

Berger hybrid target MRT Meplat reduction technology 85.5 grain .224 22 caliber bullet

This could be big news for F-TR and Palma competition, where cartridge options are limited to .223 Rem and .308 Win. Berger is introducing a NEW, very high-BC, 22-caliber Long Range Hybrid Target Bullet. Stated Ballistic Coefficents (BCs) are: 0.524 G1 and 0.268 G7. That’s near the top among .22-cal bullets and makes this 85.5 grain projectile a very viable long-range option. Want to try some? These should be available very soon. Pre-order now from Creedmoor Sports, MidwayUSA, and other vendors.

» SEE Full Report with Test Targets on Berger Site

Berger hybrid target MRT Meplat reduction technology 85.5 grain .224 22 caliber bullet

This new 85.5gr bullets boast smaller, more uniform meplats, giving them a higher long-range BC. The meplat enhancement is achieved with “Meplat Reduction Technology” (MRT). Berger Engineer Garett Stoddard, who spearheaded the MRT project, explains: “Every bullet nose is formed with optimal swage pressure determined by force instead of length. In addition to reducing a projectile’s drag by shrinking its meplat diameter, this technique takes the inherent meplat inconsistencies that plague OTM style projectiles and brings them closer to the rotational axis. This is a key factor to the consistent balance of the bullet in flight.” The new 85.5s, like all other Berger projectiles, are made with precise Berger/J-4 bullet jackets which boast +/- .0003″ jacket TIR (total indicated runout).

Berger hybrid target MRT Meplat reduction technology 85.5 grain .224 22 caliber bullet

7-Twist Barrels Recommend for new 85.5gr MRT Berger
The 85.5gr Long Range Hybrid Target Bullet’s G7 BC of .268 is achieved with optimal stability from a 1:7″-twist barrel. Berger says “Excellent accuracy may also be attained with 1:8″-twist rifle barrels, resulting in a slightly decreased BC value”.

Initial Test Results Are Very Positive
A third party tester, shooting the new 85.5-grainer in Arizona, reported excellent performance at 1000 yards: “The projectile performed extremely well at 1000 yard in spite of only being driven to ~2800 to 2850 fps. This projectile is clearly competitive at 1000 yards in a Palma rifle as tested. With a slightly longer throat and a faster-twist barrel, I am confident the 85.5 Hybrid would be a viable option for those looking to shoot .223 Rem in Long Range competitions.”

Meplat Reduction Technology Enhances Shot-to-Shot Consistency
Berger says: “Utilizing advanced and proprietary manufacturing processes, Berger’s innovative Meplat Reduction Technology (MRT) System applies controlled pressure along the projectile nose, producing a homogeneous and repeatable bullet profile for the industry’s most consistent Ballistic Coefficients (BC). While a high BC is desirable to competitive shooters, shot-to-shot BC consistency is critical when engaging targets to 1000 yards and beyond.”

How’s Your Headspace? Four Tools to Measure Shoulder Bump

shoulder bump headspace gauge comparator tool whidden manson

The Tactical Rifle Shooters Facebook Group recently showcased tools used to measure case headspace before and after “bumping” the shoulder. After a case is fired, hand-loaders who full-length size their cases will typically bump the shoulders back anywhere from .001″ to .0035″, depending on the rifle and application. With our 6mmBR and Dasher cases we like about .0015″ bump.

You want the amount of case sizing and bump to be the same for all your brass. To ensure uniformity, it makes sense to measure your cases before and after the FL sizing process. When we have time, we check every case. Other folks will simply check the first 3-4 cases coming out of the FL sizing die to ensure the FL die setting is correct and delivering desired headspace/bump.

1. Whidden Gunworks Shoulder Bump Gauge

shoulder bump headspace gauge comparator tool whidden manson

There are a variety of tools that can be used to measure shoulder bump. Our favorite is a special cartridge-specific bushing made by Whidden Gunworks. The Whidden Shoulder Bump Gauge enables you to adjust your sizing die to the desired measurement. The bump gauge is attached to your calipers with a set screw and determines the measurement from the base to the shoulder of the case. The photo below, from Tactical Rifle Shooters, shows the Whidden Bump Gauge for the .375 CheyTac cartridge.

2. Dave Manson Vertical Comparator with Dial Read-Out

shoulder bump headspace gauge comparator tool whidden manson
Background image courtesy Tactical Rifle Shooters; inset photo from Manson Precison Reamers.

Dave Manson states: “This tool was designed to make life easier for the advanced shooter and re-loader by allowing precise measurement of ammunition, case, and chamber headspace. With this information, the re-loader will be able to fine-tune clearances and fits between his ammunition and chamber, with resultant improvements in accuracy and case life.” The functions of the Comparator are:

1. Measure headspace of factory or reloaded ammunition
2. Quantify chamber headspace by measuring headspace of a fired case
3. Ensure minimal shoulder set-back when setting up re-loading dies
4. Compare base-to-ogive length to ensure consistent bullet-to-rifling relationship.

In addition to the Dial Indicator and Stand, the $130.00 Vertical Comparator is supplied with multiple Datum Blocks of precise length and inside diameter (.3300″/.3750″/.4000″/.4375″). MORE INFO HERE.

3. Hornady L-N-L Headspace Comparator System

shoulder bump headspace gauge comparator tool whidden manson

Hornady makes comparator gauges matched to the red comparator holder that mounts on your caliper. These Lock-N-Load Headspace Gauges are inexpensive. You can get a set of five gauges for $31.99. Hornady explains: “The Lock-N-Load® Headspace Comparator… gauge measures variations in brass before and after firing or re-sizing. It allows for headspace comparison between fire-formed brass and re-sized brass.” IMPORTANT: Hornady states: “To determine the proper bushing diameter for your cartridge, simply add the neck diameter and the shoulder diameter and divide that number by two. Use the bushing closest to that number.” Hornady offers five: .330″, .350″, .375″, .400″, and .420″.

One tip — We have found the Hornady gauges may vary a little from unit to unit even with the same nominal size. If you have more than one gauge for the same cartridge, test each on your brass — you may then note a slight difference in your bump measurements.

4. Pistol Brass Case DIY Bump Gauge

Last is a “field expedient” set-up if you do not have any of the comparator tools shown above. A sized .45 ACP case (or other suitable pistol case) can be used to measure shoulder bump. The mouth of the pistol case sits on the shoulder of your rifle cartridge brass.

Make sure the .45 ACP case is trimmed square and that it is round. We recommend you first run it through an expander, then size it, trim it and chamfer. Next, take the .45 ACP case and slip it over the neck of a fired, unsized rifle case with the primer removed. Align the two cases between the jaws of your calipers and note the length from rim to rim (See left photo below).

OK, now you have the length for a fired rifle case BEFORE sizing. Next, take a full-length sized rifle case (without primer) and do the same thing, placing the .45 ACP case over the neck of the FL-sized case (Right Photo). The difference between the two numbers is the amount of “bump” or set-back you are applying to the shoulder. Here the difference is .0015″. The amount of bump you need varies with your chamber and your load, but .0015-.002″ is a good initial setting.

New Toy for PRS Boys — MPA Matrix Chassis

MPA masterpiece arms precison PRS stock Matrix

MasterPiece Arms (MPA) has a new chassis system — the “MPA Matrix”. Derived from the MPA BA Chassis, the MPA Matrix Chassis offers a “multitude of configurations in grips, thumb rests, and trigger finger supports”. MPA claims the grip and hand area has over 100 different variations. The MPA Matrix has a fore-end two inches longer than the standard BA or BA Competition Chassis. Overall, the Matrix is fairly heavy, at 6.4 pounds, and pretty expensive, with a $1250-$1450 MSRP (depending on options). By contrast the MPA BA Hybrid Chassis costs $925.00 and weighs 3.5 pounds (without recoil pad).

CLICK Image for large MPA Matrix Photo:
MPA masterpiece arms precison PRS stock Matrix

There are significant design differences between the MPA Matrix and MPA BA Hybrid (below). The Matrix, at 6.4 pounds, is also much heavier than the 3.5-lb BA Hybrid. Given that many PRS/NRL competitors favor heavier rifles for greater stability (and less felt recoil), the Matrix’s extra mass is probably a good thing.

MPA masterpiece arms precison PRS stock Matrix

The MPA Matrix features five different grip options (3 swept and 2 vertical), three different thumb-rest designs and four different trigger finger supports. That’s great for shooters who like to keep their thumb forward on the bolt side of the action. However, looking at the chassis, we’re really not sure we like the way the Matrix encircles the grip area. You’ve got hard metal behind the grip. The Matrix appears set up for resting the thumb of the trigger hand alongside the action. That can work for sure, but we think some shooters will prefer a more conventional vertical grip you can wrap your thumb around. A conventional grip will also have recoil cushioning for the web of the hand. See the BA Hybrid chassis for comparison. This Matrix is really VERY different in the grip area. But if you don’t like the Matrix, there are certainly other stock options available.

The new Matrix Chassis is designed for Remington Short Actions and Rem clones. The Matrix does offer good adjustability — the buttstock has an adjustable cheek riser and length of pull adjusts from 13.5 to 14.75 inches. Plus, the recoil pad adjusts for height and cant. You can get either an adjustable rear monopod or a bag-rider configuration. As you’d expect, the MPA Matrix has M-LOK slots along the fore-end sides and barricade stop holes along the bottom.

What was the concept behind the Matrix chassis? MPA’s President, Phil Cashin, states: “One of the things that we have seen in precision rifle shooting over the past couple of years is how many different methods a shooter used to engage a stock or chassis. Due to variations in hand size, finger thickness and length, as well as shooter preference on how they want to engage the chassis or stock, we’ve seen a lot of inconsistencies among the shooters in how they engage the rifle and where they position the pad of the trigger finger with the shoe of the trigger. This inspired us to create a system that would provide a more custom fit procedure for our customers by creating a chassis with more customized configurations.”

The MPA Matrix Chassis (MSRP $1250-$1450) is available in eight Cerakote colors: Graphite Black, Flat Dark Earth, Burnt Bronze, Tungsten, Gunmetal, Sniper Green, NRA Blue, and USMC Red. Custom H Series Cerakote colors are an additional $135, while camo patterns are $450 extra.

IBS 1000-Yard National Championship Hawks Hawk's Ridge North Carolina NC 1K Heavy Gun Light HG LG Score Benchrest
Over 100 Top Shooters Competed at the 2019 IBS 1000-Yard Nationals.

Match Report by Blake Wilson, IBS Match Editor
The International Benchrest Shooters (IBS) 1000-Yard Nationals were, once again, a success. The Hawk’s Ridge Gun Club in Ferguson, North Carolina, hosted a flawless event over Labor Day Weekend. Over 100 of the nation’s top shooters, from 19 states, gathered to compete for the crown of “National Champion”. Events such as this take an army to make work and the 2019 IBS Nationals were no different. But the event was a big success, despite some challenging conditions on Day One. We congratulate Glenn Hiett, who shot superbly to win BOTH the Two-Gun Overall AND Light Gun Overall 2019 Championships. Well done Glenn! We also recognize IBS Heavy Gun Overall Champion Sam Edwards.

Ideal Conditions Change Quickly on Saturday
Hawk’s Ridge is a very beautiful range. But “The Ridge” can sometimes have very tricky, unfriendly winds. Labor Day weekend 2019 was no different. Conditions started near perfect early Saturday morning — the day began with mild temps and wind flags hanging low. Things then changed for the worse. The great conditions only lasted a handful of relays as winds became unpredictable, showing the competitors how tough Hawk’s Ridge can be. Tiny groups and high scores quickly become scarce and shooters began to feel the effects of switching, hard-to-read winds.

IBS 1000-Yard Nationals is a 6-target Aggregate event over a two-day period for Light Gun and Heavy Gun. Light Guns must not exceed 17 lbs. weight and shoot 5 rounds per target. Heavy Guns have no weight limit and shoot 10 rounds per target. At the Nationals each shooter gets three Light Gun targets and three Heavy Gun targets. The results are aggregated together to determine Two-Gun Overall, Light Gun Overall, Heavy Gun Overall. There are also separate awards for Light Gun Group and Score and Heavy Gun Group and Score.

Day 1 included a Light Gun target, Heavy Gun target and ended with a second Light Gun target. After two Light Gun targets, several shooters were feeling great about their chances — Robert Banner, Brian Buttrick, and Dan Pantinski all had 99 scores, just one from perfect. Jerry Powers had the best Day 1 Light Gun Agg, a 3.472″ average (0.33 MOA). Justin Morrow shot the smallest Light Gun Group — 2.604″. That works out to a very impressive 0.249 MOA at 1000 Yards!

Donna Matthews shot this excellent 50-2X, 3.257″ LG target on Saturday.

Participants Rewarded with Famous Hawk’s Ridge BBQ
As Saturday came to an end, the smell of chicken had taken over the range. Range owner Mike McNeil is known for his famous secret sauce BBQ chicken. From the comments of the crowd as they sunk their teeth into chicken, potato salad, fresh baked desserts — they had no complaints whatsoever. Bellies full, guns cleaned, everyone headed to their rooms for some much anticipated rest.

More Readable and Consistent Conditions on Day 2
Feeling refreshed and excited for the challenge and anticipation for the final day, shooters showed up raving about the BBQ chicken and ready to shoot. For the most part, Day 2 was much more forgiving and calm than Day 1. The format was the opposite of Saturday — Heavy Gun relays were conducted first and last with Light Gun in the middle.

Perfect scores, small groups and everything in between was shot. Shooters made adjustments and for the most part they worked. But some made the wrong choices and the price was paid.

Editor’s Comment: Looking at the Two-Gun Top 20 Equipment List above, we see the Light Gun Ranks were dominated by 6mm Dashers, and 6 BRAs (BR Ackleys), most using Hodgdon H4895 powder. There were quite a few 300 WSMs among the top Heavy Guns. Krieger, with 10 selections, was the most popular barrel choice, followed by Bartlein (4), and Brux (3).

More than Marksmanship — Competitors Appreciate the Camaraderie
These events are always a pleasure to attend. You get to put faces with the names you’ve heard, compete against the best across the country, and see how you stack up to them. It’s fun to shake hands with the likes of Tom Jacobs (Vapor Trail Bullets past National Champion), Bart Sauter (Bart’s Bullets and current holder of 600-yard records), Mike Wilson (Current Light Gun Group and score record holder), the Hornady Team and many more.

Heat Build-Up and Firing Rate Can Kill a Barrel Prematurely

barrel life test rapid fire cooling

Can sustained rapid-fire shooting with no cool-down period wear out a quality barrel more quickly? The answer is “Yes” according to Forum member LCazador, who did an interesting comparison test with two .243 Winchester barrels. He started off with two, identical, match-grade HV taper stainless barrels. Both were NEW at the start of testing, and LCazador shot the same load through each: 95gr match bullets with 38 grains of Hodgdon Varget. After giving both barrels the same, gentle 20-round break-in, 300 rounds were then fired through each barrel — in very different ways. Barrel condition and wear were monitored with a borescope.

Barrel One — Slow Fire, Cool Down Periods, Cleaning Every 50 Rounds
At the end of the 300-round test, Barrel One looked brand new. There was none of the severe fire cracking found in Barrel Two. This barrel was shot no more than 10 times without a cool down and firing was done at a much slower pace. Cleaning for this barrel was done every 50 shots.

Barrel Two — Fast Firing, No Waiting, Cleaning Every 100 Rounds
The second barrel, which received hard use and minimal cleaning, was severely damaged with severe fire cracking at the leade and throat. As a result, the barrel had to be re-chambered. This barrel was shot 100 rounds at time without cleaning and was shot up to 20 times in succession without a cool down.

LESSON LEARNED — Heat Kills Barrel Life
Don’t let your barrel get too hot, and keep it clean. One afternoon can ruin a barrel!

Hawkeye Borescope imageMonitoring Barrel Wear with Borescope
Some folks worry too much about what their borescopes reveal — many barrels do not have to be “squeaky clean” to perform well. In fact some barrels run better after ten or more fouling shots. However, a borescope can be very helpful when your barrel starts losing accuracy for no apparent reason. Forum member FdShuster writes:

“A borescope is a positive way of backing up your suspicions when the rifle starts to throw an occasional (soon followed by more frequent) wild shot. Using the scope is also an excellent way to determine that the cause is barrel wear and not simply a need for a concentrated cleaning session to remove built up copper and more importantly, carbon fouling.

I’ve had a few barrels that gave every indication of being shot out. But I ‘scoped them out and found the cause to be nothing more than requiring a good cleaning. They then returned to their usual performance. There’s no guessing involved when you are able to get ‘up close and personal’ using the scope. The borescope also provides an excellent view of the all-important condition of the crown. My borescope is one of the most valuable investments I’ve ever made.”
