Nammo AS Lapua Berger Bullets Vihtavuori SK ammunition brass bullets powder Capstone Precision Group LLC Sedalia Missouri MO logistics center new

Some major players in the shooting world — Lapua and Berger Bullets, have joined forces under the Nammo AS umbrella. And now, along with Vihtavuori and SK, these businesses will be operated together as Capstone Precision Group, LLC. And Capstone will soon have a new facility in Missouri. A new 30,000-square-foot logistics center has been leased in Pettis County, outside Sedalia. From here, products will be sent to dealers and wholesalers throughout the USA. Capstone Precision Group will invest almost $1 million to launch the new facility.

Missouri’s Governor welcomed Capstone: “Capstone Precision Group’s decision to grow its business in Missouri is great news for families in rural Pettis County. This new distribution center means new quality jobs for hard working Missourians,” said Gov. Eric Greitens. “We’re grateful to Capstone Precision Group for recognizing that Missouri is open for business and our people are ready to work.” LINK: Missouri Department of Economic Development.

NEW Logistics Center for Capstone Precision Group
Nammo AS, an international aerospace and defense company headquartered in Norway, announced that the newly-formed Capstone Precision Group LLC will launch its U.S. logistics center in Pettis County, outside Sedalia. This facility will be the U.S. logistics center for Capstone Precision Group’s four commercial ammunition brands — Lapua, Berger, VihtaVuori, and SK. Additionally, ammunition, components, and smokeless powder will be imported from Finland and Germany and distributed in the U.S. and also exported, while projectiles from the company’s Mesa, Arizona, location will be shipped to Missouri for packaging and distribution.

IBS Report: 31st Annual Boop Memorial Benchrest Match 2017

IBS Benchrest Shooters International Memorial Match Weikert PA Jeff Stover
Al Auman, 2-Gun Second Place finisher, takes aim…

IBS 31st Annual Memorial Match at Union County Sportsmen’s Club, Weikert, PA
Reported by Jeff Stover, IBS President
The “Boop Shoot” is traditionally held on Mother’s Day in May, but this year it was moved to June due to a club conflict. No matter, as 63 shooters showed up on June 10th and 11th, 2017 to compete at one of the best benchrest ranges in the country. “Weikert” is nestled in a narrow valley in pastoral central Pennsylvania and has a wide following since the IBS Nationals have been held there a number of times.

The 2-Gun Aggregate represents “all the marbles” — the overall win for a weekend of Short Range Group shooting. Accuracy gunsmith Dave Bruno won the 2-Gun with a .2606 Agg shooting his 6PPC built on a Borden action in a Roy Hunter stock. On Dave’s heels was Al Auman, shooting a Goodling-built 6PPC BAT. In third place was Paul Mitchell with his BAT 3-Lug in a Scarborough stock built by Dwight Scott. The 2-Gun Aggregate is the combined average group size for 20 targets total, 10 each for both the Light Varmint (10.5-lb) and Heavy Varmint (13.5-lb) classes, with shooting at both 100 and 200 yards. Despite the class distinctions based solely on rifle weight, a vast majority of shooters opt for a 10.5-lb rifle for the entire course of fire. You get a lot of shooting at an IBS Registered Group match.

The Tailwind from Hell
The real story of this match was the shooting conditions. For the entire weekend, there was a tail wind. When the wind blows hard, a pure tailwind is favored by many veteran shooters as velocity changes are less apparent on the target compared to a pure crosswind where pickups and letups can be mapped on the record target of a less-than-observant trigger puller. At this match, it was a tailwind from hell. The over-the-shoulder wind veered from red (right to left) to green (left to right) as quickly as it took you to read this sentence. The point of impact in the extremes could cause groups of 1.5 inches at 200 yards. It was one of those shoots where posting a .824” 200-yard group could move you up in the standings. Normally shooting an “eight” would assure a “bottom of the pile” finish.

Sunday morning saw that nefarious tailwind doing its dirty work once again, but it was not quite as bad as the afternoon would turn out to be. The tailwind’s impact, however, could be seen in the fact that the Heavy Varmint 200-yard winner was upstate NY shooter, Jim Miller with a .2817 (200-yard Aggregates are recorded in MOA, so Jim’s average group at 200 yards was .563”). He was the only competitor in the “twos”. Bob White shot well but his .3012 was not enough.

Dave Bruno Dominates Light Varmint 200
Light Varmint 200 was shot after lunch on Sunday. The winds had picked up while the shooters were enjoying burgers and hot dogs from the range house. This last Aggregate was the climax of the entire weekend. Two-gun winner Dave Bruno set the stage for his overall win by shooting as if he were from another planet. He was on fire with a .2388 Aggregate. Next was Bob Brushingham with a .3024. That is a difference of .0636” in average group size, or about 1/16th of an inch. A sixteenth is not much in most things, but in short range benchrest it is a chasm that Evel Knievel would not dare to test. Most Aggregates in benchrest are won and lost by a few thousands, or even ten-thousands of an inch. Dave blew out the field with his singular performance. When asked what condition he shot, Dave said “the tailwind” — go figure.

Yes, 100-yard was also contested. Back in the day, a “Teen Agg” (an aggregate of targets under .200”) was usually shot in perfect, or mild, readable conditions. The level of shooting in recent years, however, has seen Teen Aggs shot in tough conditions. The aforementioned tailwind prevailed on Saturday too, but was just a bit less nasty.

Loading at the range remains important in the Benchrest for Group discipline. In a Special Report below, IBS President Jeff Stover explains how loading methods (and hardware) have evolved over the years.

More Teen Aggs were shot in the Heavy Varmint relays. Benchrest Hall of Fame shooter Allen Arnette recorded a tiny .1686. On the podium with Allen were Howie Levy with a .1808 and Willie Bauer who shot a .1980.

Memorial Shoot Is a Family Affair
The 2017 Annual Boop Memorial Shoot ran like clockwork, as usual, and once again the success of this annual shoot can be attributed to the Trutt and Boop families. Mark Trutt serves as range officer extraordinaire. Dale Boop is match director while his mother, Linda, handles the administrative and scoring chores. Target crew honcho Steve Dodge, once again, ensured a rapid and accurate changing of the target.

NOTE: It has yet to be determined whether 2018 Memorial Match will be on Mother’s Day or in June.

Loading at the Range — Then and Now

IBS Benchrest Shooters International Memorial Match Weikert PA Jeff Stover

In benchrest shooting for group, loading at the range has been de rigueur for decades. In the Score discipline, preloading is usually the custom. The main reason is that, in Score competition, only one Aggregate (warm-up match and five record targets) per day is usually shot. That would be less than 50 shots, assuming a few sighter shots. Also, the 30BR, the dominant Score cartridge, is amenable to pre-loading.

By contrast, the Group discipline includes 21 targets (two warm-ups and twenty record targets) over a weekend, usually shot with 6PPC-chambered rifles. Many times, the 6PPC shooters may tweak their loads through the day given changing atmospheric conditions or simply trying to find the correct tune to “dot up”. This term, “Dot up”, means the shots are essentially going through the same hole, or closely so.

IBS Benchrest Shooters International Memorial Match Weikert PA Jeff Stover

Loading at the range was a bit different when benchrest competition was in its infancy. The 1951 book, Modern Accuracy by Bob Wallack, is the best of the early benchrest books. Copies can be found, from time to time, on eBay or Alibris. It is a fascinating survey of benchrest as it existed more than six decades ago. There’s even coverage of a controversial target that was argued over at the time. In it, there is a photo of Wallack using the rear bumper of a car at the bench to clamp his reloading tools. Things have come a long way compared to the range loading set-ups of modern shooters. Here you can see Bob Wallack way back in 1950:

Shiney Savings: Wet-Tumbling Cartridge Brass on a Tight Budget

Brass Tumbling stainless media cheap Harbor Freight Brass plated cartridge brass

Super Clean Brass Without Breaking The Bank

Posted on June 21, 2017 by Sierra Bullets
Written by Sierra Bullets Ballistic Technician Gary Prisendorf

I recently purchased 1,000 rounds of once-fired 5.56 LC brass that was fully processed and ready to load. The brass had been wet tumbled, using stainless steel pins and looked great inside and out, including the primer pockets.

I had always used a vibrating tumbler with either corn cob or walnut media and I always thought my brass looked pretty good until I saw what the wet tumbling and pin combination did.

Being the budget minded reloader that I am, I started looking for a cheap way to wet tumble my brass using stainless steel pins. Harbor Freight had recently opened a store nearby and I had received coupons in the mail, one of the coupons was 20% off any one item.

So I headed for the Harbor Freight store and after roaming around for 20 minutes or so I found a dual drum rotary rock tumbler for $55.00 and thought it would do just fine for what I was planning. The drums are rather small and only have a 3 pound maximum load limit each, but I figured that was big enough for around 150 .223 cases or maybe 300 9MM cases at a time.

I pulled the wrinkled up coupon out of my pocket, paid, and walked out with my new $47.00 brass cleaning machine. I didn’t have any stainless steel pins and couldn’t find any locally. At our local hardware store I picked up some brass plated ½” finishing brads that I thought might work until I could get some pins ordered.

I bought two small packages of the finishing brads(1.75 oz.), for $1.69 each then headed to my local Walmart to pick up some Dawn dish soap (.99 cents) and a bottle of Lemi Shine ($3.27). I had read online that is what a lot of people use for cleaning their brass.

I bought two small packages of the finishing brads (1.75 oz.), for $1.69 each then headed to my local Walmart to pick up some Dawn dish soap (.99 cents) and a bottle of Lemi Shine ($3.27). I had read online that is what a lot of people use for cleaning their brass.

When I got home, I started depriming .223 brass for my new toy, I mean brass tumbler. I deprimed 100 cases, put 50 in each drum, dropped a package of brads in each one, filled them ¾ of the way with water, gave each drum a small squirt of Dawn dish soap and a tablespoon of Lemi Shine. I sealed up the drums and fired up the tumbler.

After an hour and a half, I just couldn’t stand it any longer and had to see the results. The water was filthy but the cases were super clean, I couldn’t be happier. For a total investment of around $55.00, I can now get my cases looking almost new.

Here are the before and after pictures of my first run of brass:

Brass Tumbling stainless media cheap Harbor Freight Brass plated cartridge brass

I have since ordered two pounds of stainless steel pins, I put one pound in each drum. To be honest the brass really doesn’t look any better, but the pins don’t seem to get stuck inside of the cases near as bad as the brass-plated brads did.

Tip: Make sure to inspect your cases and look inside each case to ensure all of the brads/pins are removed.

Just lay the brass and brads/pins out on a towel and let them dry. Mine were dry after about 12 hours.

If you want your cases to look like new without breaking the bank, give it a try. You can’t clean 1000 at a time like the $200.00 tumbling machines that are made for specifically for brass, but this is a much cheaper alternative and the results speak for themselves. — Gary Prisendorf, Sierra Bullets

EDITOR: Actually you can get a machine for a whole lot less than $200.00! See the next paragraph.

Lyman Cylone Rotary Tumbler with Factory Rebate
Sierra’s Technician got his rotary tumbler and brass media for $55.00. For about twice that you can get a much better, higher-capacity system from Lyman. The Lyman Cyclone Rotary Tumbler features a large, polymer drum that holds up to 1000 .223 Rem cases. The kit includes media separation trays, plus five pounds of correct STAINLESS media. The Lyman Cyclone system costs $156.54 delivered from Amazon but this product qualifies for a $25 REBATE from Lyman. That puts your net cost at $131.54 for a complete Cyclone system. To be honest we think that’s money well spent, compared to the “El Cheapo” Harbor Freight unit. The Lyman will run six times as many .223 Rem cases, and get the job done faster. We suspect long-term durability will be better with the Lyman tumbler as well.

Wildcattin’ Wisdom — Good Resource for Wildcat Cartridges

Zegline Wildcat Cartridges ManualAre you a wildcatter? We know many of our readers like to invent new cartridge types. If that applies to you, here’s a great resource…

Fred Zeglin has released a Kindle eBook edition of his popular book Wildcat Cartridges — Reloader’s Handbook of Wildcat Cartridge Design. Gunsmith/author Zeglin explains: “The print edition of Wildcat Cartridges has gone out of print. We have plans to produce a second edition, but that is currently on the back burner. Demand of this book has remained strong so the decision to offer the first edition in a e-book format was made.” The Kindle eBook edition retails for $9.99 on Amazon.com. You can preview a FREE SAMPLE of the book to “try before you buy”.

CLICK HERE to Read FREE eBook Sample from Zeglin’s Wildcat Cartridges

This is more than just a history of cartridges. Dimensional drawings and loading data accompany many cartridge descriptions. More recent/popular designs are included as well as “classic” older wildcats. There are chapters about important cartridge designers like P.O. Ackley, Jerry Gebby, Rocky Gibbs, and Charles Newton. (The hardback edition of the book contains 288 pages of stories, illustrations, instructions, and data.)

Gunwriter Wayne Van Zwoll says Zeglin’s book is a valuable resource: “Fred has illustrated his book well, with neat line drawings and photos you probably won’t find anywhere else. It’s a rare technical treatise that draws you in with illustration, or that keeps you with an easy flow of chat that, were it lifted from print, might pop up at any gun counter or handloading bench. Fred Zeglin has done well with this book, giving wildcatters – indeed, all rifle enthusiasts – an overview of a culture often mentioned but little explored on the page.”

Writing about the 2005 Print Edition of Wildcat Cartridges, Big Bore Journal declared: “This is a fantastic book on American wildcats, U.S. loads and much more. A must have for wildcatters and gunsmiths.”

Tech Nightmare: CMP Electronic Target Problem at Camp Perry

KTS Electronic Targets failure Camp Perry Excellence Competition EIC

By Steve Cooper, CMP North General Manager & Ashley Brugnone, CMP Writer
In disappointing fashion to all involved, the CMP [cancelled] its June 17 Excellence-In-Competition match when significant damage was done to the target system following the successful completion of standing and rapid-fire sitting stages at 200 yards by nearly 100 competitors.

KTS Electronic Targets failure Camp Perry Excellence Competition EIC
Nearly 100 competitors took to the firing line on Viale Range for Saturday’s EIC Rifle Match.

The CMP EIC match was the historic debut of the latest in scoring technology on the “big” ranges at the 101-year-old Ohio National Guard training site near Port Clinton. The match fired on Viale Range was a fill-in for a previously cancelled Ohio Rifle & Pistol Association event. CMP is in its second year of operating 10 electronic target lanes at 100 yards for rifle and five lanes for pistol at Camp Perry’s Petrarca Range. CMP also operates two 80-point electronic indoor airgun ranges at Camp Perry and Anniston, AL, respectively.

During the changeover from 200 to 300 yards at the Saturday event, multiple targets were damaged when newly-trained CMP target workers accidentally strained or tore several interconnecting cables on the target line while raising and lowering target carriers. Diagnostics showed several targets were showing errors, but CMP technicians believed many targets could be salvaged and some were repaired.

The loss cut the range from 35 to 19 serviceable targets. CMP staff and competitors agreed to shrink the size of the range, re-squadding shooters into more relays on the remaining working targets. After repairs were made, firing continued with the prone rapid-fire stage at 300 yards. When firing was complete, a handful of shooters received inconsistent information on their monitors. A re-fire was conducted for that group and many of the re-fire group still reported target errors.

KTS Electronic Targets failure Camp Perry Excellence Competition EIC
Members of CMP staff convene to discuss abnormalities during the 300-yard prone rapid-fire stage of the EIC Rifle Match. Moments later, the match was called off after it was determined too many targets were compromised by damaged cables in the Viale Range pits.

It became clear that the initial damage to the target communication system was worse than originally thought. Christie Sewell, CMP Programs Chief, explained to competitors that it was impractical to go any further and had no choice but to cancel the match. CMP offered refunds to all competitors or the option of crediting their entry fees to a future match. The match did not count toward the competitors’ EIC match total for 2017.

The Takeaway from this Experience – CMP is a Pioneer in the Electronic Target World
They say it’s easy to recognize pioneers — they’re the ones with arrows in their backs. It feels that way sometimes at the Civilian Marksmanship Program as we roll out the most sophisticated electronically-scored targets in the world to America’s bullseye rifle and pistol shooters. Sometimes we make mistakes and they cost us time, money and aggravation.

KTS Electronic Targets failure Camp Perry Excellence Competition EIC
Cables carry power + communications from target to target the length of the line. Many places between targets can trap and catch cables. The loss of 1 cable can take out 5 adjacent targets.

But we press on. And the competitors who understand our goals press on with us. We pull the arrows out of each other’s backs, cover shot holes with thick-skin pasters, learn from our mistakes and press on with our mission. That mission includes safety instruction, youth marksmanship fundamentals, growing the sport of bullseye target shooting and providing our competitors the best opportunity to maximize participation in this sport.

What Actually Went Wrong on Saturday
Those familiar with the KTS targets at the CMP Talladega Marksmanship Park know they are hard-wired and mounted to actuators that tilt the targets up and down for use on three different target lines. Shooters fire from a common covered firing line and fire distances of 200, 300 or 600 yards during open public sessions and matches without moving. Those targets are semi-permanent and fit into frames that are bolted to iron brackets mounted on a concrete deck.

Tactical Twins: Micarta-Stocked PRS Rigs for SFC Brandon Green

SFC Brandon Green PRS Rifle Micarta Foundation Stocks

What does a two-time High Power National Champion choose for PRS comps? A set of twins. Twin rifles that is. SFC Brandon Green of the USAMU is one of America’s best marksmen. He’s excelled in Service Rifle and High Power disciplines, and now he’s getting very serious about the Precision Rifle Series (PRS). Brandon recently took delivery of “Twins” — two impressive rifles optimized for PRS competition. Green told us: “The Twins are ready for business! The silver one is a 6XC and the black one is a 6.5×47 Lapua”. Both rifles feature Impact Precision actions (with AICS-type mags), 24″ Proof stainless barrels, and Fat Bastard muzzle brakes. Rifle work was done by Stuteville Precision (Wade Stuteville) and Exodus Rifles (Joe Walls).

SFC Brandon Green PRS Rifle Micarta Foundation Stocks
In the 6XC, Brandon runs Berger 105gr VLDs in Norma 6XC brass. For the 6.5×47 Lapua he shoots 140gr Berger Hybrids or 143gr Hornady ELD-Xs in Lapua brass. Both rifles have stainless steel Proof barrels, but the 6.5x47L has a matte black Cerakote finish.

Brandon loves his new Twins. He said he likes the “feel” of the guns with the Foundation stocks: “These rifles weigh around 17 pounds with optics. They feel very solid under recoil — without the ‘tuning fork’ vibration you can get with a metal-chassis gun. They feel like a good wood-stocked gun, but the material is stronger and more rigid than wood. I’ve heard that guys are having success with these Foundation stocks with the actions installed without pillars or conventional bedding.” Currently Brandon is running both guns without action-screw pillars. He did have one skim-bedded, but he doesn’t think that was really needed. “Both rifles hammer now”, Brandon tells us.

Green Runs Vortex Razor HD Gen II 4.5-27x56mm FFP scopes on both rifles:
SFC Brandon Green PRS Rifle Micarta Foundation Stocks

High-Tech Micarta Stock Material
At first glance, those stocks may look like wood, but they are actually a special “Micarta” material that is strong, durable, and stable. Micarta, often used for knife handles, is a “a brand name for composites of fiberglass, carbon fiber, or other fabric in a thermosetting plastic.” The stock-maker, Foundation Stocks, says Micarta offers some distinct advantages over laminated wood or conventional fiberglass: “The solid block of material gives us a dense, homogenous material that is absent of any voids or air pockets commonly found in composite stocks. The high compression strength of the material allows us to build an action/DBM specific stock that requires no bedding or pillars. The material is very durable and stable in extreme environments. We use advanced CAD software to design and model our stocks, working in conjunction with action manufacturers and rifle builders to provide exact fitment.”

Here is a close-up of a Foundation Stock showing the distinctive Micarta texture:

Tactical Competition vs. NRA High Power Competition
Brandon says PRS competition is tough: “PRS can be pretty humbling, but it’s been a lot of fun and a great challenge. For a shooter (like me) with a Service Rifle/High Power background, the variations in stages combined with the time limits can be very challenging. And the unusual shooting positions put a new spin on things. PRS is definitely a different ball game, but I really enjoy it. After the National Championships this summer I hope to shoot three or four PRS matches in September and October.”

Tangent vs. Secant vs. Hybrid — Bullet Ogive Geometry Explained

Secant and Tangent Ogive Bryan LitzWe know many of our readers aren’t 100% clear on the difference between a secant ogive bullet and a tangent ogive bullet. Add the “blended” or “hybrid” ogive into the design equation and you add to the confusion. In this article, Berger Ballistician Bryan Litz, explains the characteristics of the three popular ogive types: tangent, secant, and hybrid.

In discussions of ballistics, you’ll see references to “tangent” and “secant” bullet shapes. For many readers, these terms can be confusing. To add to the confusion, bullet makers don’t always identify their projectiles as secant or tangent designs. This article provides a basic explanation of tangent and secant designs, to help you understand the characteristics of both bullet shapes.

Tangent vs. Secant vs. Hybrid
Most match bullets produced today use a tangent ogive profile, but the modern VLD-style bullets employ a secant profile. To further complicate matters, the latest generation of “Hybrid” projectiles from Berger Bullets feature a blended secant + tangent profile to combine the best qualities of both nose shapes. The secant section provides reduced drag, while the tangent section makes the bullet easier to tune, i.e. less sensitive to bullet seating depth position.

Berger Bullets ballistician Bryan Litz explains tangent and secant bullet ogive designs in a glossary section of his Applied Ballistics website, which we reprint below. Bryan then explains how tangent and secant profiles can be combined in a “hybrid” design.

How Bullet Ogive Curves are Defined
While the term “ogive” is often used to describe the particular point on the bullet where the curve reaches full bullet diameter, in fact the “ogive” properly refers to the entire curve of the bullet from the tip to the full-diameter straight section — the shank. Understanding then, that the ogive is a curve, how is that curve described?

LITZ: The ogive of a bullet is usually characterized by the length of its radius. This radius is often given in calibers instead of inches. For example, an 8 ogive 6mm bullet has an ogive that is a segment of a circular arc with a radius of 8*.243 = 1.952”. A .30-caliber bullet with an 8 ogive will be proportionally the same as the 8 ogive 6mm bullet, but the actual radius will be 2.464” for the .30 caliber bullet.

For a given nose length, if an ogive is perfectly tangent, it will have a very specific radius. Any radius longer than that will cause the ogive to be secant. Secant ogives can range from very mild (short radius) to very aggressive (long radius). The drag of a secant ogive is minimized when its radius is twice as long as a tangent ogive radius. In other words, if a tangent ogive has an 8 caliber radius, then the longest practical secant ogive radius is 16 calibers long for a given nose length.”

hybrid bullet

Ogive Metrics and Rt/R Ratio
LITZ: There is a number that’s used to quantify how secant an ogive is. The metric is known as the Rt/R ratio and it’s the ratio of the tangent ogive radius to the actual ogive radius for a given bullet. In the above example, the 16 caliber ogive would have an Rt/R ratio of 0.5. The number 0.5 is therefore the lowest practical value for the Rt/R ratio, and represents the minimum drag ogive for a given length. An ogive that’s perfectly tangent will have an Rt/R ratio of 1.0. Most ogives are in between an Rt/R of 1.0 and 0.5. The dimensioned drawings at the end of my Applied Ballistics book provide the bullets ogive radius in calibers, as well as the Rt/R ratio. In short, the Rt/R ratio is simply a measure of how secant an ogive is. 1.0 is not secant at all, 0.5 is as secant as it gets.

Berger Hybrid bullet, .308 30 CaliberHybrid Bullet Design — Best of Both Worlds?
Bryan Litz has developed a number of modern “Hybrid” design bullets for Berger. The objective of Bryan’s design work has been to achieve a very low drag design that is also “not finicky”. Normal (non-hybrid) secant designs, such as the Berger 105gr VLD, deliver very impressive BC values, but the bullets can be sensitive to seating depth. Montana’s Tom Mousel has set world records with the Berger 105gr VLD in his 6mm Dasher, but he tells us “seating depth is critical to the best accuracy”. Tom says a mere .003″ seating depth change “makes a difference”. In an effort to produce more forgiving high-BC bullets, Bryan Litz developed the hybrid tangent/secant bullet shape.

“This is My Rifle” — 74-Year-Old Marine Reunited with M1 Garand

Pat Farmer USMC Marine Corps M1 Garand CMP Camp Matthews
After 56 years Pat Farmer was reunited with the M1 Garand he used while serving his country.

By Ashley Brugnone, CMP Writer
Pat Farmer hadn’t felt the weight in his hands in 56 years. After five decades, the memories flooded back as his fingertips grazed the wood of the stock and gripped it tightly. It was a piece of his personal history, and the history of his country… and now, it’s a relic he’ll be able to keep for the rest of his life.

“I had never dreamed it would be in the CMP (Civilian Marksmanship Program) warehouse,” he said. “I had just hoped to possibly start a search beginning with the CMP.”

The 74-year-old from Jacksonville, NC, is a retired veteran who served 26 years in the armed forces. He was raised on a farm in Nebraska where he became familiar with guns at an early age. As a teen, he enlisted in the U.S. Marine Corps during his senior year in high school through a delay program. On August 30, 1960, he left for the Marine Corps Recruit Depot in San Diego, California, to attend boot camp — where he celebrated his 18th birthday.

Upon arrival he was issued M1 Garand #4305638. The firearm soon became a close companion as he spent countless hours with it on the “Grinder” — a Marine Corps term for a deck or parade ground used for drill and formations.

Reunited with M1 Garand after 56 Years
On May 8, 2017, Pat Farmer was reunited with M1 Garand #4305638 thanks to the CMP. Bringing it back to life, Pat began to fieldstrip the rifle. As he got to the trigger housing of the gun, he found something that he couldn’t believe – tape with his name and markings on it. It read, “Farmer 20/8L.” Pat believes it was his 500-yard “dope” – twenty clicks elevation, eight clicks left windage.

“Fifty-six years ago, we drilled and did the manual of arms with M1s as if they were matchsticks. It seems much heavier now!” Farmer added with a laugh.

Pat was eventually selected for aviation school after infantry training and shot on the rifle team while attached to a Reserve unit. He went on to shoot expert rifle at the Camp Mathews rifle range*. “It was some of the best and most rewarding years of my life,” he said.

Many years later, Pat one day went through an old locker box and found his custody receipt from Jan. 27, 1961, when he turned in his boot camp rifle before transferring to aviation school. Curiosity set in as he wondered whatever became of M1 Garand #4305638 – and the idea of finding it overcame him.

“I had purchased a few rifles from the old DCM and also CMP, so on a whim I decided to contact CMP to see if my old M1 had ever passed through their system,” he explained. Here’s the story of what happened and the years of waiting…

Bargain Finder 91: Accurateshooter’s Deals of the Week

Accurateshooter Bargain Finder Deals of Week

At the request of our readers, we provide select “Deals of the Week”. Every Monday morning we offer our Best Bargain selections. Here are some of the best deals on firearms, hardware, reloading components, and shooting accessories. Be aware that sale prices are subject to change, and once clearance inventory is sold, it’s gone for good. You snooze you lose.

1. CDNN — Browning Stainless Buck Mark, $279.99 After Rebate

Browning Buckmark Stainless Camper UFX Pistol Handgun .22 LR 22 rimfire

Everyone needs a good .22 LR rimfire handgun, and the Browning Buck Mark is a classic. This stainless, bull barrel version is marked down this week to $329.99. That’s a very good deal, but you can save even more with Browning’s $50 Rebate. Buck Marks, with their excellent triggers and great ergonomics, are fun to shoot and VERY accurate. This is a pistol you can keep for a life-time. Browning says: “Every Buck Mark starts out as a solid piece of aircraft-grade 7075 aluminum alloy, and then is CNC-machined to exacting tolerances. The crisp single-action trigger, hand reamed chamber, target crowned barrel and finely adjustable target sights mean the Buck Mark comes ready for fun straight from the box.” There is also a blued Buck Mark version priced at $289.99 (or $239.99 after Rebate).

2. Grafs.com — Caldwell Long Range Target Cam System, $329.99

Amazon Caldwell Precision Long Range Target System Cam Camera
Labradar chronograph

Forum members have purchased this Caldwell Target Cam System and they’ve found that it works reliably, providing a clear signal to any WiFi-enabled mobile device (smartphone, iPad, Laptop). One member specifically tested the unit at 1000 yards and it functioned fine. NOTE: This system does NOT have a zoom camera lens, so you need to position the camera within 10 yards or so of the target. But if you place it to the side a bit, this shouldn’t be a problem. This system comes with a nice, fitted carrying case that holds camera, transceivers, antennas, and stands. You get a very capable system for under $330.00. Graf’s offers free shipping after a flat $7.95 handling charge.

3. Midsouth or Bruno’s — Labradar Chronograph and Accessories

Labradar chronograph

Midsouth Shooters Supply is now carrying the advanced Labradar chronograph. This unique unit allows you to measure your shots without having to set up a tripod and skyscreens downrange. When you start using a Labradar, you’ll never want to go back to old-style chronographs. You can also purchase the Labradar from Bruno Shooters Supply. Price is $559.95 from either vendor. NOTE: Very soon Labradar plans to offer Bluetooth functionality, allowing you to control the machine remotely with your mobile device. This functionality will come via new software — the Bluetooth transceiver is built-in to all current Labradar units, so you can buy one now and use Bluetooth later (when the software is released).

4. Lyman — $25.00 Off Top-Selling Products

Lyman rebate mail-in borecam cyclone powder measure, Case Prep Xpress

You can now get $25.00 Off five of Lyman’s top-selling products: BoreCam, Case Prep Xpress, Gen6 Powder Dispenser, Cyclone Rotary Tumbler, and AutoAdvance Target. With Lyman’s Summer Mail-In Rebate Program, you can earn a $25 rebate per select item bought from any Lyman dealer, online or direct from the Lyman website.

Gen6 Compact Digital Powder System (Item #7750550)
AutoAdvance Remote Control Target System (Item #4320051)

5. Whittaker Guns — Howa Lightning 6.5 Creedmoor Rifle, $299.99

With this deal you can get a complete 6.5 Creedmoor Howa 1500 Rifle with HACT 2-Stage Trigger for just $299.99. That’s $150.00 less than the price of a Howa 1500 barreled action by itself! ($449.99 at Brownells). This is a no-frills rifle, but its hard to beat the $299.99 price for a solid, multi-purpose rifle. Use “As-Is” for hunting or drop it into a modular stock for tactical/practical games.

6. Amazon — RCBS Rock Chucker Supreme Press, $126.99

Amazon.com Amazon RCBS Rock Chucker Supreme Single Stage Reloading Press Sale

The RCBS Rock Chucker remains a classic — a big, strong, versatile press that can handle most reloading chores with ease. And now you can get a genuine Rock Chucker Supreme for $126.99 — a very good deal. The Rock Chucker offers plenty of leverage for case-sizing and the “O” is tall enough for long cartridges. The Rock Chucker has a very strong base and should last a lifetime. We’re not fans of the Rock Chucker’s priming system but most serious reloaders use a separate priming tool.

7. Amazon — Neiko Digital Calipers, $16.79

Amazon Neiko Digital Caliper

Even if you have a good set of calipers, you may want to get one of these Neiko 01407A Digital Calipers. The #1 best-selling digital caliper on Amazon.com, this Neiko tool features a large LCD Screen and measures up to 6.0 inches. With 2850+ customer reviews, this product has earned an overall rating of 4.4 out of 5 stars. It’s hard to go wrong for $16.79, even if you just use these as a spare set for measuring group sizes and case trim lengths.

8. Midsouth — 17 HMR V-Max Ammo, $9.75 for 50 rounds

17 HMR Hornady Midsouth V-Max Vmax Sale

Need 17 HMR ammo for your planned 2017 varmint safaris? Then grab this Hornady V-Max ammo while you can at $9.75 for a 50-round box. This is a great price. Other vendors are selling the same Hornady ammo for as much as $13.50 per box. We’ve used this ammo and it was very accurate out of both semi-auto (Savage A17) and bolt-action (CZ 455) 17 HMR rifles.

Panda Perfected — Ignition Timing for Kelbly Panda Action

Alex Wheeler Accuracy gunsmith Panda Kelbly Stolle action timing receiver benchrest video

Kelbly makes outstanding actions, including the Stolle Pandas. In the past 20 years, Pandas have probably won more benchrest matches than any other action (though BATs and Bordens are increasingly in the winning circle). Recently gunsmith Alex Wheeler of Wheeler Accuracy worked his magic on an aluminum Panda, optimizing the “ignition timing” of the action. This involves many small mods to bolt, camming surfaces, trigger, and firing pin: “The whole cam helix and detent shelf is re-cut. The firing pin and cocking piece are modified as well.” When executed properly, Ignition Timing has a number of benefits, including a smoother bolt opening/closing, improved firing pin fall, and enhanced accuracy (though the accuracy improvements can be subtle).

BEFORE Action Timing — Stiff and Clunky

Alex reports: “Normally Panda actions have plenty of firing pin fall. For one reason or another this one was very low. Before timing, firing pin fall was .210 with a Bix’N Andy (BNA) trigger. After trigger timing firing pin fall is .244 with zero cock on close.” Here is how the action functioned before timing work:

Alex notes: “As you can see, after the cocking piece rides out of the detent notch it then
falls to the trigger and is then re-cocked. This is normal on most un-timed actions.”

AFTER Action Timing — Smooth and Refined

Alex explains the modifications he made for this Panda action: “Moving the trigger back adds cock on close. The whole cam helix and detent shelf is re-cut. The firing pin and cocking piece are modified as well. I do love a timed Panda. In fact, I like aluminum actions, I think there is something to them. But yes, I also recommend Borden as my first choice.’

Fix for Right-Bolt Actions Only
After seeing these videos on Facebook, one poster asked: “I do like my Panda but this is exactly why I bought a Borden action and I love it. It’s good to know you can make a Panda better. Alex, can you time a left bolt Panda?”

Alex replied: “No, the tooling I built is all for right hand actions sorry….”
