Oregon Wilderness Camp Serves Recent Combat Veterans

Camp Divide Oregon Veteran Wilderness Camp

Finding Peace On The Other Side Of War
NRA Blog Story by Catherine Parks, Divide Camp Volunteer

For combat veterans there is a great divide between life pre-war and life post-war. Soldiers prepare, train and are equipped to go to a war zone, but, upon returning home, physically and psychologically injured veterans struggle to assimilate back into a normal life. Divide Camp, located in northeastern Oregon, honors the service of post 9-11 combat veterans through small-group outdoor adventures. The non-profit camp offers hunting, fishing, and other recreational activities. Learn More HERE.

Divide Camp provides lodging, home-cooked meals and transportation at no charge to the veterans served. The camp features 40 acres of remote forestland, six cabins, a shop and an outdoor picnic shelter. In 2014, The NRA Foundation funded its first grant to Divide Camp — $15,000 for an Action Trackchair — to allow amputee veterans to traverse the mountain terrain.

Another grant in 2015 funded pistol range construction, safety gear and targets. Initial range work for a competition 3-D archery course shootable from a Trackchair began with funding from an NRA Foundation grant in 2016.

How Divide Camp Helps Rebuild Lives
Army veteran Jose Martinez stepped on an improvised explosive device in Afghanistan. Following numerous surgeries and months of therapy, Jose was fitted with prosthetics, which allowed him to walk. Still, extreme depression set in and two suicide attempts followed. On his first day at Divide Camp, Jose used the new all-terrain wheelchair to hunt. “I missed the first couple of times, but my friends didn’t give up on me and Divide Camp didn’t give up on me, and I got one the next morning,” Jose said. “Elk hunting was one of the best experiences I’ve ever had. How many amputees in California can say they shot an elk?” Jose stayed in a new cabin built to accommodate veterans with disabilities.

Just being in nature is an amazing healer
Julie Wheeler, Divide Camp executive director, has served as a critical incident stress worker to help others prevent post-traumatic stress disorder. She is familiar with what happens when people are exposed to high stress and trauma. “I know it takes a long time to overcome,” Julie said. “I think they need help beyond what’s provided by the Department of Veterans Affairs, which is drugs and therapy. Just being in nature is an amazing healer.”

British Shooter Wins Big at CMP Western Games

CMP 2017 Western Games

Ellis Wins Three-Gun and Four-Gun Titles at 2017 Western CMP Games
Story based on Report by Ashley Brugnone, CMP Writer
In a masterful showing of marksmanship, William Ellis of Langley, England won both the Three-Gun and Four-Gun Aggregate rifle competitions during the CMP Western Games in Phoenix last month. 2017 was a great year for Ellis, who first traveled to the Western Games in 2009. William’s 2017 performances earned him the second Distinguished Rifleman Badge by a non-U.S. citizen this past year.

CMP Western Games Vintage Sniper rifle

Earning twin Aggregate Titles was a great accomplishment for Ellis, who had nearly won three years ago. In 2014, Ellis was the runner-up (second-place) in both 3-Gun and 4-Gun. But this was Ellis’s year — he was unstoppable. He shot superbly in the Arizona desert, taking the top spot in the Springfield Rifle Match along with second place in the Vintage Military Match. Those strong showings helped earn Ellis the 3-Gun and 4-Gun overall victories. To accompany his centerfire victories, Ellis shot great in the Rimfire Match, winning the Tactical Class. This was truly a masterful five days of shooting by Ellis.

Ellis Will Be Featured on Shooting USA
The media took notice of Ellis, who may have traveled farther than any other competitor at this year’s Western Games. Ellis will be featured in a Carbine Match video segment by Shooting USA TV, which filmed portions of the 2017 CMP Western Games for an upcoming episode.

Hot Day-Time Temps and Wicked Night Winds at Ben Avery
2017 Western Games competitors experienced hot weather in Phoenix. Temperatures reached well into the 90s each day. The afternoon of the Sniper team match day saw temps topping out at 102° F. But the real weather problem was a gale-force wind that howled one night. The CMP’s 30 electronic targets were set up on the berm in front of the High Power rifle range pits wall. After the Small Arms Firing School was concluded, 40+ MPH overnight wind gusts toppled the entire target line. Thanks to the CMP staff and several competitors, the majority of the targets were reset, and all matches were fired upon them for the scheduled day and the remainder of the matches.

About the CMP Western Games at Ben Avery
The CMP Western Games include Garand, Springfield, Vintage Military, Modern Military, Rimfire Sporter, Carbine, and Vintage Sniper matches. The October Western Games event is the last of the CMP Travel Games events held each year. The other Travel Games, hosted in Oklahoma, North Carolina, and New England, feature both vintage and modern rifle and pistol events — recreational competition for both adults and juniors and all experience levels. The Western Games is the only Travel event for rifles only.

Bore Cleaning The Right Way — Top Barrel-Makers Give Advice

Shooting Sports Lohman Barrel

Ask 10 shooters about barrel cleaning and you’ll get 10 different opinions. This reflects that fact that different fouling problems demand different solutions. For example, solvents that work well for copper may not be the best for hard carbon (and vice-versa). To come up with the right solution, first you must understand the nature of the fouling in your barrel.

CLICK HERE to read Full Match Barrel Care Article »

Chip Lohman, former Editor of Shooting Sports USA Magazine, has authored an excellent article on barrel maintenance and cleaning. Chip’s article, Let the BARREL Tell You — Match Barrel Care, is in the Shooting Sports USA digital archives. In this article, Chip shares the knowledge of a dozen experts including respected barrel-makers Frank Green (Bartlein Barrels), John Krieger (Krieger Barrels), Dan Lilja (Lilja Barrels), and Tim North (Broughton Barrels).

John Krieger Interview with AccurateShooter at SHOT Show:

The debate about the proper care of a match barrel is a hot one, spiked with folklore and old wives’ tales, Lohman said. He and his staff set out to set the record straight: “We tried to interject some science into the discussion of cleaning a match barrel,” he explained. In his article, Lohman writes:

Why worry about a little barrel fouling when the throat is subjected to a brutal 5,600° F volcano at 55,000 PSI? To investigate these and other questions about taking care of a match barrel, we spoke with a dozen experts and share their knowledge in this first of a series of articles.

After listening to folks who shoot, build barrels or manufacture cleaning solvents for a living, we concluded that even the experts each have their own unique recommendations on how to care for a match barrel. But they all agree on one thing — the gun will tell you what it likes best. Because the life expectancy of a match barrel is about 1,500 to 2,500 rounds, the objectives of cleaning one should include: preserve accuracy, slow the erosion, and remove fouling — all without damaging the gun. This article doesn’t claim that one cleaning method is better than the next. Rather, we set out to interject a little science into the discussion and to share some lessons learned from experts in the field.

National High Power Championships in Shooting Sports USA

John Whidden Long Range Championship Shooting Sports USA Anette Wachter

We were pleased to see our friend John Whidden featured in the October 2017 issue of Shooting Sports USA. John captured the 2017 NRA Long Range Championship this summer, his second LR title in a row, and fifth overall. This year was a bit different, as the competition was held in Indiana at Camp Atterbury. All John’s previous Long Range HP titles were earned at Camp Perry.

Whidden’s Perfect Palma Match
Whidden secured the 2017 LR Title by shooting “clean” (not dropping a point) in the tough Palma competition. In the NRA Palma match, rifles must be .223 Rem or .308 Winchester, with metallic sights (no scopes). The match is conducted at three yardages, 15 shots at each distance of 800/900/1000 yards, with unlimited sighters at 800 and two sighters at 900 and 1000.

SSUSA’s Editor John Parker writes: “On another note, this month’s cover feature highlights the very first NRA High Power Rifle Championships conducted at the match’s new home—Indiana’s Camp Atterbury. Located about 50 miles south of Indianapolis, this active Indiana National Guard base boasts over 60 ranges, making it the ideal new venue to continue the legacy of NRA High Power. Hundreds of competitors made the trek to continue the historic tradition of rifle competition at the National Matches.”

Sling Rifle Evolved: The Ultra-Accurate Hybrid Palma Rifle

John Whidden Palma Rifle .308 Win Barnard Anschutz P action smallbore stock

Since John captured his fifth Long Range crown with a superb performance in the Palma match, we thought we’d give readers a look at John’s very special Palma rifle. This unique .308 Win prone rifle features a Barnard “P” action in a converted aluminum Anschutz “Precise” smallbore (rimfire) stock. The combo of Barnard action and Anschutz ergonomics is hard to beat, says John, who told us: “this is easily the best Palma rifle I’ve ever had.” John told us this gun handles like no other: “After recoil, with this Anschutz stock, the sights fall right back on target — better than any other prone rifle I’ve shot”.

As a bonus, the Barnard “drop-in” required no modification of the Anschutz Precise stock. This means John can actually swap in his rimfire barreled action and shoot smallbore with the same stock.

Trigger: Barnard Two-Stage adjustable

Whidden’s Wonder-Gun: German Stock, New Zealand Action, American Barrel
John built this Palma rifle in early 2016. With it, John won back-to-back long-range Championships in 2016 (Camp Perry) and 2017 (Camp Atterbury). The major components are: Barnard ‘P’ action, Anschutz Precise smallbore stock, and Bartlein barrel. The caliber is .308 Win, as dictated by the Palma rules. Palma matches are fired from 800, 900, and 1000 yards utilizing iron sights only. No optical sights are allowed.

IBS Match Report: 2017 1000-Yard Nationals in West Virginia

IBS 1000-yard Nationals White Horse West Virginia

2017 IBS 1000-Yard Benchrest Nationals
Report By Boyd Allen
On September 1-4, the IBS held its 2017 1000-yard Benchrest Nationals at the Whitehorse Shooting Center in Peeltree, West Virginia. There was a great turn-out this year, with 118 entries in Light Gun Class (17-lb limit, 5 shots per target) class and 107 shooters in Heavy Gun Class (Unlimited weight, 10 shots per target). The conditions this year were challenging to say the least, with rain storms, spiraling winds, and fog. In fact, rain and fog on Saturday (with cancelled relays) caused the Nationals to be extended by one day through Monday, September 4th. What’s more, of the 107 shooters listed in the Two-Gun Overall results who actually shot both guns, there were dozens of DQs. (Yes, the wind was a bit tricky at this year’s Nationals.)

Sam Hall, past IBS Shooter of the Year, provided this image and most of the photos in this report.

Congratulations to the “top guns” at the Nationals: Edward Kenzakoski (Two-Gun Overall Champion), Mike Gaizauskas (Light Gun Overall, plus LG Score Agg), and Mike Brennan (Heavy Gun Overall, plus HG Score Agg). Group Agg winners were Richard Schatz for LG, and Charlie Lentz for Heavy. Two ladies also deserve mention. Sally Bauer shot the smallest group of the match, a 1.923″ 5-shot group in LG — that’s 0.184 MOA! Ruth Edwards drilled a 2.104″, also mighty impressive. Nice shootin’ ladies…

White Horse Wind and Weather Factors — and Topography
The firing line for the 1000-yard range has a covered structure with 14 well-spaced masonry benches with block bases and cast concrete tops. Facing southwest, the firing line is above the land between it and the target butts, which are at the head of a canyon. There is a low area with trees on the left with an elevated flat area on the right.

IBS 1000-yard Nationals White Horse West Virginia

This topography create unpredictable wind patterns that can change rapidly with no warning. Those changes can wreak havoc with competitors’ groups and scores. The wind direction at the targets can be opposite that at the firing line, with the result that a let-off down range not only carries the penalty of making a hold-off incorrect, but because the wind at the firing line can continue, adding the additional penalty of a reversal. This was the common cause of disqualifications, which were numerous at this year’s Nationals.

Delay Caused by Fog and Rain
On Saturday, rain and fog delays, caused the match to be extended through Monday. The rules dictate that if a full match cannot be finished because of weather, then all of the day’s results are discarded. This meant that even those shooters who completed their relays on Saturday had to shoot them over — hence another day was added to the event. Because of the prospect of worsening conditions on Saturday afternoon, even though there was daylight left, the decision was made to extend the match through Monday.

Profile of 2017 IBS 1000-Yard National Champion Edward Kenzakoski

Commenting on his performance at the Nationals, Ed said modestly:
“I didn’t shoot really good. I just shot better than them other guys.”

IBS 1000-yard Nationals White Horse West Virginia

Winning Hardware (with a 110-lb Heavy Gun)
Notably, Ed does all of his own gunsmithing, and he built his Championship-winning rifles. Both guns featured 1:11″-twist, 30″ Krieger barrels. (LG: 1.250″ shank and .950 muzzle; HG: 2″ contour untapered). Ed’s Light Gun has a BAT action, no barrel block, Jewell trigger, and McMillan Tooley MBR stock. His Heavy Gun boasts a 10″-long BAT action in a two-piece aluminum stock with barrel block. That HG beast weighs 110 pounds! Both of Ed’s rifles (light and heavy) wore Nightforce 12-42x56mm BR scopes.

Winning Numbers
To win the Two Gun Overall, Ed posted 137 LG Score, 262 HG Score, and 399 Two-Gun Score Agg. His Group numbers were: LG Group 5.659, HG Group 7.483, Two-Gun Agg: 6.571.

Winning Loads and Reloading Methods
Both rifles are chambered in 300 WSM. Ed shoots 210gr Berger VLDs (sorted every way possible), with Norma brass, Hodgdon H4350 powder, and CCI BR2 primers. For the two guns he used very different seating depths — barely touching for the HG, 0.100″ jump for the LG. He said that it takes him a full four days to load the ammunition for both rifles for a match. Yes, he weighs primers, and he even passes his bullets through a .309 bushing.

No Dark Horse at White Horse — Kenzakoski is a Proven Winner
One shouldn’t be surprised at Edward Kenzakoski’s success. Ed really cleaned up at Williamsport this year, winning one 6-match Aggregate and two 10-match score and group Aggregates. He also established a new Williamsport club Light Gun record of 3.2″.

Record-Setting Asymmetry
In 2016 Michael Gaizauskas set the current 1000-yard IBS Heavy Gun (10 shot) group and score records. He set those records with the rifle on the left (below), then chambered in 6.5×47 Lapua. In this match, Mike won LG Group and LG Overall with the rifle on the right as chambered in his own 7mm short magnum wildcat. Mike designed and built both these distinctive assymetric stocks.

White Horse Shooting Center Facilities, Organization, and Location
The 1000-yard range used at the IBS 2017 Nationals is part of a large shooting facility run by Whitehorse Firearms Outdoor Education Center in cooperation with the West Virginia Division of Natural Resources. White Horse is located off of Route 20 near the small community of Peeltree, WV. The nearest town of any size, ten miles to the south, is Buckhannon, WV, which has about 5600 residents.

IBS 1000-yard Nationals White Horse West Virginia

White Horse Geography and Climate
The White Horse range is set in wooded hill country, with lots of creeks and some smaller rivers all kept green and running by an annual rainfall of about 48 inches and about the same for snowfall. To my eyes it is beautiful county, pleasingly rural and lush, in marked contrast to where I live where every plant must be served by some sort of irrigation.

The Science of Annealing — Facts Uncovered, Myths Busted

Annealing Made Perfect Testing AMP cartridge Case hardness Lapua Norma Lake City

The science behind annealing during the manufacture of new cases is well-established. What happens after that, when we repeatedly reload and anneal those same cases, has always been somewhat of a “dark art”. To help separate scientific fact from fiction, the creators of the Annealing Made Perfect (AMP) Annealer machine have conducted detailed studies of cartridge brass. The AMP Team’s studies offer some remarkable insights, while disproving a number of myths about annealing. Will annealing tighten your groups? The evidence of these studies shows it could.

The test results are fascinating. The team compared brands of brass, sectioning brass to examine both alloy composition and thickness from case mouth to case-head (bottom). They also examined how carbon build-up affects next tension. And they determined how brass changes over multiple loading cycles. They even did a series of bullet-pull tests to analyze factors affecting neck tension. Here are some of the key subjects in the reports:

Brand by Brand Analysis — How the cartridge brass alloy varies among different manufacturers.
Bullet Release and Neck Tension — Tensile Bullet-Pull tests show factors affecting neck tension.
Neck Tension and Carbon — How carbon build-up inside the neck affects “neck tension”.
SS Tumbling and Hardness – How tumbling with stainless media affects brass hardness.
Case Cleaning (Ultrasound and Tumbling) — How case cleaning affects annealing.
Multiple Loadings — How brass performs when annealed every reload over 10+ cycles.

Annealing Made Perfect Testing AMP cartridge Case hardness Lapua Norma Lake City

You really should read the reports — there are some fascinating revelations. The AMP team made longitudinal sections of various cases to show different case wall thicknesses and head geometry. These examples also show how the hardness of the case varies from the case mouth to the case-head. Both virgin and used, annealed cases were examined.

Bullet-Pull Tests — Using advanced tensile test equipment, AMP experimented with different combinations of dies, reloading sequences, and neck hardness to ascertain the best practice.
Annealing Made Perfect Testing AMP cartridge Case hardness Lapua Norma Lake City

Carbon Inside Your Case-Necks May Be a GOOD Thing
AMP’s testers found carbon in necks can be beneficial: “Even with identical interference fit and neck hardness, as the carbon layer increased (microscopically), the force to draw the bullet decreased. It would appear the carbon acted as a lubricant. Interestingly, the [pull force] standard deviation also improved, i.e. the case to case variation in the force required to draw the bullets decreased.”*

Read the Full Test Reports

The AMP team’s objectives were to clarify some misconceptions on just what annealing does and does not do, and also to establish the best practices for consistent results. They have consulted with three independent certified metallurgy laboratories to produce some definitive information. So far, the Stage 1 and Stage 2 reports have been released. The studies include a report on the general physical properties of cartridge brass, including grain structures, hardness scales, time/temperature annealing information, and what can cause de-zincification.

The FULL REPORTS, including comprehensive appendices, are found here:

Stage One: https://www.ampannealing.com/articles/40/annealing-under-the-microscope/

Stage Two: https://www.ampannealing.com/articles/42/annealing-under-the-microscope/

Annealing Made Perfect Testing AMP cartridge Case hardness Lapua Norma Lake City

Examining Different Brands of Brass — What the Tests Revealed

Is Lapua brass harder than Norma? Is Lake City better than Remington? You’ll find answers to these and other questions in AMP’s annealing studies. One of the key findings in Stage 2 of Amp’s research is that brass from different manufacturers does vary in the distribution of material in the walls of the case.

Annealing Made Perfect Testing AMP cartridge Case hardness Lapua Norma Lake City

Stage Two Conclusions:

— Different brands of the same cartridge cases can require different annealing power settings due to differing case wall thickness in the neck and shoulder region. The greater the mass of brass to be annealed, the greater the power requirement. Lot to lot variation within the same brand can occur for the same reason.

— The bushing die used in this set of tensile bullet pull tests gave significantly more consistent results than the standard neck die with expander ball.

— Cases should be annealed every reload in order to get the best repeatability.

Case Variations: Brand to Brand, and Lot to Lot

Here is a sample from AMP’s test report:

Analyzing Different Brands of Brass
In our Stage One report, we demonstrated that there is insufficient variation in alloy composition between brands to account for the variations we experience when annealing different brands of the same cartridge case. We therefore sought to confirm that it is the mass of brass to be annealed which accounts for the difference. Below are sectioned samples of four different brands of .223 Remington cases.

Both the Lapua and Norma neck walls are 314* microns (0.01236”) at the mouth. The Lapua neck wall thickens to 348 microns at the junction of the neck and shoulder, and the Norma neck thickens to 325 microns. Through the shoulder, however, the walls of both cases thicken to 370 – 380 microns. Once past the shoulder, they both taper back to 314 microns, before starting to thicken again, moving towards the case head.

The Lapua case requires AMP Program 47 to anneal correctly. It is the heaviest of the four cases tested through the shoulder region. The Norma case, which is only slightly lighter through the same region, needs Program 43.

The Remington case is very similar to the Lapua and Norma cases in the neck region, but it actually thins fractionally through the shoulder and front section of the body. The AMP program setting for Remington 223R is P32.

The Lake City case is the thinnest throughout of all four samples. It only requires Program 28.
