September 11-17, the Bald Eagles Rifle Club hosted the 2011 Spirit Of America rifle match, at the NRA Whittington Center in Raton, NM. This match serves as U.S. National Fullbore Championships, but there are also F-Class divisions. The match consists of conventional sling (TR) class, as well as F-Open and F-TR, and the event is shot at distances of 300, 500, 600, 800, 900 and 1000 yards. Approximately 80 shooters, including about 20 F-classer attended the event.
Bryan Litz won the Fullbore TR (sling) competition with a 1782-105X overall score, with runner-up Andrew Wilde (1780-101X), just two points behind. Sean Morris finished third with 1776-85X, and Jim O’Connell shot 1772-81X to claim the High Senior title.

In F-Open Class, familiar names topped the leaderboard. Larry Bartholome earned his chair ride as F-Open winner, shooting an impressive 1776-98X. Second in F-Open, five points back at 1771-96X, was past F-Class National Champion Danny Biggs. In the F-TR division, Michael Smith topped the field with a 1738-69X, followed by John Killen, who shot a 1720-52X. NOTE: F-Open and F-TR competitors shoot a target with smaller-diameter scoring rings than the Fullbore Target.
Conditions Were Mild… Then Wild
Bryan Litz tells us the conditions weren’t so bad … until the final day: “We dodged some rain throughout the week, but wind conditions were easy to moderate for the most part. That is until the last 1000-yard string of the last day when Raton finally showed its evil side! The most wind I had used all week was just over 3 MOA. That last relay on Saturday, it was running between 7 and 12 MOA with very quick changes. There were many misses, and just keeping all shots in the black was an accomplishment.” Rick Hunt concurred that the conditions were arduous on the final 1K stage: “At 1000 yards, there was a 9:00 o’clock wind running between 9 1/2 and 13 1/2 MOA. As seen by the scores, two shooters really nailed it. Other than that, it was pretty disastrous for most shooters with the really fast velocity changes.”
When the smoke had cleared, the standings were all jumbled up compared to what they were the rest of the week. Litz added: “An experience like that really drives home the importance of wind shooting skills. To be honest, I had no particular strategy going in other than to stay calm and positive no matter what. A big part of shooting in adverse conditions is managing yourself mentally. I dropped 10 points that last relay, more than I’d lost in the entire tournament up to that point. But given the conditions, I felt good about it, knowing I’d done my best.”
Berger 155gr Hybrids Work Well in Fullbore Competition
Bryan Litz credits his 155gr Berger .308-cal Hybrids for his strong performance: “I was shooting the new Berger 155 grain Hybrid bullets which played a part in saving some points in that nasty wind (on the last day). Due to their length, these bullets require a 1:12″ twist to stabilize and have a higher BC than any other .30 caliber 155 grain bullet. The hybrid ogive makes them length tolerant (insensitive to seating depth) and as the results of this tournament show, they are very effective”.

At the match the USA Young Eagles unveiled the new uniforms the American team will wear at the World Fullbore Championships in Australia next month. On opposite sleeves, the uniforms feature logos from both major bullet sponsors — Berger and Sierra. Bryan Litz observerd: “Historically teams have been sponsored by ‘one or the other’, but there’s no reason a team can’t enjoy sponsorship by multiple brands, and this is a very positive step in that direction.”
Get ready for a major new technology that could change the benchrest game. Carlos (Carlito) Gonzales, a benchrest shooter (and Professor of Engineering) from Argentina, has perfected a horizontal, external “floating” cartridge loader that can reliably feed PPC cartridges as fast as you can work the bolt.
We have received a report that Gonzales’s fast-feeding device has been approved by the NBRSA for use in benchrest matches. Pascal Fischbach told us: “I had an email September 17th from Gene Bukys, [stating] that the board of directors of the NBRSA approved the use of the ‘[Gonzales] manual cartridge feeder’ for use in NBRSA competitions.” [Editor’s note: We don’t yet know if the device is approved for all NBRSA benchrest matches, or just short-range matches.] Pascal added: “The device was presented at the delegates meeting of the WBC11 in France and approved for use during the World Championships. The next step for Carlito will be to market it. He is also willing to license the concept, plans, and methods to a machinist capable of manufacturing it in the USA.” See Discussion Thread.
External Horizontal Cartridge-Feeder
The Gonzales loading device is an open-ended, covered metal tray situated on the left side of the action (but it does not touch the gun — it is supported by an arm attached to the front rest). This feeds into the left-side loading port. The cases are gravity-fed, but the shooter has positive control over feeding. A cable with a push-button control runs from the magazine down to the rear foot of the pedestal rest. You just push the button to drop one cartridge from the magazine. We don’t know exactly how the cartridge is released in the magazine itself, but in the video below you can see how the push-button works.
You push the button as soon as a spent cartridge ejects (watch Carlito’s left hand in the video above). It is a clever set-up that works very, very fast. The video shows Carlos running five cartridges through his action in just 9 seconds (time marker 00:31 – 00:40). That’s fast! On a repeat viewing focus on Carlito’s left hand to see how he works the push-button cartridge dispensing control.

Here’s a little known fact that may startle most readers, even experienced gunsmiths: your barrel wears out in a matter of seconds. The useful life of a typical match barrel, in terms of actual bullet-in-barrel time, is only a few seconds. How can that be, you ask? Well you need to look at the actual time that bullets spend traveling through the bore during the barrel’s useful life. (Hint: it’s not very long).
Bullet-Time-in-Barrel Calculations
If a bullet flies at 3000 fps, it will pass through a 24″ (two-foot) barrel in 1/1500th of a second. If you have a useful barrel life of 3000 rounds, that would translate to just two seconds of actual bullet-in-barrel operating time.
Ah, but it’s not that simple. Your bullet starts at zero velocity and then accelerates as it passes through the bore, so the projectile’s average velocity is not the same as the 3000 fps muzzle velocity. So how long does a centerfire bullet (with 3000 fps MV) typically stay in the bore? The answer is about .002 seconds. This number was calculated by Varmint Al, who is a really smart engineer dude who worked at the Lawrence Livermore Laboratory, a government think tank that develops neutron bombs, fusion reactors and other simple stuff.
On his Barrel Tuner page, Varmint Al figured out that the amount of time a bullet spends in a barrel during firing is under .002 seconds. Al writes: “The approximate time that it takes a 3300 fps muzzle velocity bullet to exit the barrel, assuming a constant acceleration, is 0.0011 seconds. Actual exit times would be longer since the bullet is not under constant acceleration.”
We’ll use the .002 number for our calculations here, knowing that the exact number depends on barrel length and muzzle velocity. But .002 is a good average that errs, if anything, on the side of more barrel operating life rather than less.
So, if a bullet spends .002 seconds in the barrel during each shot, and you get 3000 rounds of accurate barrel life, how much actual firing time does the barrel deliver before it loses accuracy? That’s simple math: 3000 x .002 seconds = 6 seconds.
Gone in Six Seconds. Want to Cry Now?
Six seconds. That’s how long your barrel actually functions (in terms of bullet-in-barrel shot time) before it “goes south.” Yes, we know some barrels last longer than 3000 rounds. On the other hand, plenty of .243 Win and 6.5-284 barrels lose accuracy in 1500 rounds or less. If your barrel loses accuracy at the 1500-round mark, then it only worked for three seconds! Of course, if you are shooting a “long-lived” .308 Win that goes 5000 rounds before losing accuracy, then you get a whopping TEN seconds of barrel life. Anyway you look at it, a rifle barrel has very little longevity, when you consider actual firing time.
People already lament the high cost of replacing barrels. Now that you know how short-lived barrels really are, you can complain even louder. Of course our analysis does give you even more of an excuse to buy a nice new Bartlein, Krieger, Shilen etc. barrel for that fine rifle of yours.
Are there significant metallurgical differences in the alloys used in various brands of cartridge brass? The answer is yes, and we have proof. Using a state-of-the-art X-Ray Fluorescence Spectrometer, some tech-savy Wisconsin shooters recently analyzed the alloys in seven different types of cartridge brass.
The test results revealed significant differences in the percentages of copper and zinc in the different brands. Copper content ranged from a low of 72% by mass (Winchester, S&B) to a high of 80% by mass (Remington). Zinc, which adds hardness to the alloy, ranged from a low of 20% by mass (Federal) to a high of 36% (‘brown box’ Lapua). Interestingly, the tests, as reported by Forum Member Fred Bohl, revealed that the alloy in the new ‘blue box’ 6mmBR Lapua brass is different than the alloy in Lapua’s older ‘brown box’ 6mmBR brass. Specifically, the ‘blue box’ 6mmBR brass has more copper and less tin (by mass). Here’s a summary of the X-Ray Fluorescence spectrometry tests:
This testing was done at major science laboratory, using high-grade X-Ray Spectrometry Analyzing equipment. Fred reports that: “The data was run by one of the club members with the permission of the test lab supervisor who is also a club member and shooter. The data in original output reports was far more detailed about trace elements at lower orders of magnitude primarily from surface contaminants (some were rerun after establishing a repeatable cleaning procedure)”. The testing process is discussed in this Shooters’ Forum thread.
We do NOT have the metallurgical expertise to infer that any particular alloy shown above is “better” than another. The alloy “blend” is merely one of many variables that can have an impact on the performance and quality of the finished product. Annealing times/methods differ and some cartridge brass is extruded while other cartridge brass is made with the traditional drawing process. Readers should not presume, on reading the above chart, that they can identify the “best shooting” brass simply based on the constituent metals in the various alloys.
General Observations about Cartridge Brass Alloys
With the cartridge brass X-Ray Spectrometry results in hand, Fred Bohl hoped to find out what “real world” conclusions (if any) we could draw from the raw data. Fred sent the test results to some knowledgeable metallurgists, soliciting their comments. Fred explains: “When I first posted this information [in the Shooters’ Forum], I had hoped to elicit replies from expert metallurgists and to initiate a useful discussion. From [their replies] I distilled the following ‘consensus’ comments”:
1. The range of Copper/Zinc ratios suitable for use in cartridge making by typical processes is 85/15 to 65/35 (% by weight or mass).
2. The range of Copper/Zinc ratios suitable for use in cartridges intended for reloading is 80/20 to 70/30. Above 80% copper, the resulting case would tend to be too soft and difficult to attain the distribution of hardness desired (harder at the base and softer at the neck). Below 70% copper the resulting case would tend to be too hard, would work harden too quickly and require frequent annealing. [Editor: That said, the ‘brown box’ 6mmBR Lapua brass, with 62% copper/36% zinc content, enjoys an unrivaled reputation for both accuracy and its ability to perform well after a dozen or more reloading cycles. We know 30BR shooters who have shot the same old-style Lapua brass (6mmBR parent case) more than 50 times. So maybe the “expert” view needs re-thinking.]
3. As the percentage of zinc increases, the tensile strength, yield strength and hardness tend to increase. However, above 35% zinc, while tensile strength will continue to tend to increase, both yield strength and hardness will tend to begin to decrease.
4. The trace additives of iron and/or silicon are used to control the processing characteristics of the alloy. Trace additions of chromium will improve corrosion resistance and give a shinier surface (both largely cosmetic).
5. Selection of the alloy and additives is a trade off among: end use desired properties; processing time and yield; and cost of materials. For example, the classic 70/30 cartridge brass was considered an optimum combination of corrosion resistance and hardness for single use by the military with good process yield at acceptable material cost.
6. All of my responding experts were surprised by the brown box Lapua alloy except for the oldest. He remembered using an almost identical alloy late in WWII when copper was in very short supply for military small arms ammunition.
Distribution of CH-Reticle Benchrest Scopes Will Be Limited
If you’re looking for a Nightforce 12-42×56 Benchrest model scope with a CH-series reticle, you may want to act soon. Nightforce is reducing production of these models and the limited runs will be strictly earmarked for Nightforce’s most active dealers. (NF Benchrest scopes with other reticle choices will continue to be widely available). Nightforce’s CH (i.e. cross-hair) reticles, are offered in three versions: CH-1 (fine cross-hair), CH-2 (fine cross-hair with 0.2 MOA inscribed dot), and CH-3 (fine cross-hair with 0.2 MOA “floating” dot). The CH reticles have always been popular with benchresters, as they provide an unobstructed view of mirage and windflags. The CH-2 reticle has been used by the USAMU for long-range and High Power competition. The CH-3 includes an open area around the 0.2 MOA dot, which makes the dot easier to see on dark backgrounds. On the CH-3, only the dot can be illuminated.
Where to Find Nightforce BR Models with CH Reticles
The CH-series reticles are no longer offered in the lower-power 8-32×56 BR model at all. If you want a CH reticle in a NF Benchrest scope, you’ll need to order the 12-42×56 scope. AND, you’ll now need to order from a major stocking dealer. EuroOptic.com currently has one of the largest inventories of 12-42×56 BR Nightforce scopes with CH Reticles — it has about 50 of these CH reticle Benchrest scopes in stock. To order, call (570) 220-3159, ask for Jason Baney and mention that you heard about these CH reticle scopes through the Daily Bulletin. Jason will make sure you get the right CH reticle version at the best possible price. Another large stocking dealer of Nightforce scopes is D&B Supply, found on the web at ScopeUsOut.com.
Later this month, GLOCK, Inc. will donate a total of $75,000 to two organizations, the Young Marines and the Marine Corps League. On Wednesday, Sept. 28th, Glock V.P. Josh Dorsey (a former Marine) will present $50,000 to the Young Marines and $25,000 to the Marine Corps League during a presentation held at the Iwo Jima Memorial, Quantico, Virginia.
$50,000 to Young Marines
This will be the sixth consecutive year that Glock has made this contribution to the Young Marines totaling $300,000. The Young Marines is a nonprofit youth organization whose mission is to provides programs for youth that promote mental, moral and physical health through teamwork, self-discipline and a drug-free lifestyle. The program strives to instill core values of “Honor, Courage and Commitment” adopted by each member of the Marine Corps.
$25,000 to Marine Corps League
This is the second year that Glock has made a contribution to this organization. The Marine Corps League is comprised of retired Marines volunteers who render assistance to all Marines and former Marines and to the families of fallen Marines. The group actively supports injured Marines, and assists youth programs. The League takes an active role in Veterans benefits issues and helps with the National Marine Corps Museum.
Forum member Lee G. (aka ‘SkeetLee’) has built a fully enclosed, 4-season shoot house with loading area. The new shoot house, located on his parents’ farm, will make most readers envious. The quality of the slab and the framing is a far sight better than what you’ll find in many tract houses. SkeetLee has experience in concrete work and construction and he did a beautiful job on his new facility, which combines a large reloading area with two concrete benches facing out to a 200-yard range. The insulated shoot house will be heated in winter, allowing year-round shooting.
Construction Planning and Progress
SkeetLee tells us: “We added 16′ to the back of the machine shop on one of our farms so I could have a place to practice my shooting. Everything worked out real well because exactly 200 yards out from the new addition is a low spot in the field that doesn’t produce any crop anyway, so we thought this would be a good spot for a berm. I started building the berm this spring before the crop got planted and it is about 60% complete. I am very lucky to have such a place to do all this, and I will be forever indebted to my folks for letting me build this range and loading/shoot room. This range is a gift to me from my folks, and I am very grateful.”
SkeetLee will be using the new shoot house very soon: “I finally have the room at least 95% done. It took the better part of the year to complete and there is still some work to do to the berm once the corn [comes] down next week, but the shoot house is darn near ready for some banging.”
Below are the two benches in progress. SkeetLee set the block in mortar then formed the tops in place with some “T” supports to hold the forms up. He used an 8″ sona tube for the rear leg, then added Re-Bar for reinforcement. It worked out really really well as you can see in the bottom photo.
Shoot House Permits Year-Round Shooting
SkeetLee notes: “This winter when the snow is flying we can stay warm and shoot until our finger(s) get sore. I also look forward to entertaining some guests.” To give our readers a better view of the interior of his shoot house, SkeetLee recorded a two-part video. Part Two is embedded below, and you can CLICK HERE for Part One.
MGM Tactical has been selected as the bullet trap, target and range equipment supplier for the largest indoor shooting range in the country, the planned Colonial Shooting Academy (CSA) in Richmond, Virginia. Construction is scheduled to be completed in February 2012. The Colonial Shooting Academy choose MGM Tactical because MGM offers state-of-the-art bullet containment systems with unique capabilities. These include:
“Impact” system rifle-grade Shoot House
“Deep V” bullet traps with .50-caliber capability
“Shoot Close” granulated rubber bullet trap for the tactical range.
The facility will have multiple ranges, a shoot house, retail selling area, offices, café, classrooms and member lounge. The facility will have five separate ranges: one 11-lane tactical range; two 25-yard mezzanine-level ranges (one with 11 lanes and one with 14 lanes); and, two additional private 7-lane ranges. All ranges will have acoustical tiles for sound deadening. The building’s basement will house a high-tech, 1590-square-foot, multi-room shoot house with multiple entries and breach doors.
The 2011 IBS Nationals were held at the White Horse Center Range near Peeltree, West Virginia. This was a 3-target Aggregate match for both Light Gun (LG) and Heavy Gun (HG) with six (6) targets total. The big winner was Shooters’ Forum member Tod Soeby (aka 4Xforfun). Tod, who hails from North Dakota, drove a long way to the match, but his journey was well worth it, as he topped a large, highly-competitive field of 117 shooters. Soeby won BOTH the 2-Gun Overall as well as the Light Gun Group+Score Overall (In Light Gun, Tod was #1 for Group and #6 for Score, shooting a 6mm Dasher). Soeby’s Light Gun Group Agg was a remarkable 3.884″, nearly an inch smaller than the next best Light Gun Group Agg, a 4.724″, turned in by Salley Bauer. Gordy Gritters finished second in 2-Gun Overall, while David Powell secured third place in 2-Gun Overall.
Tod’s three, 5-shot Light Gun groups were: 4.489″, 3.760″, and 3.283″. That yielded an average of 3.884″ at 1000 yards. Think about that — Tod’s average is barely over one-third MOA, which is 3.49″ at 1000 yards — seriously small. Yes, those Dashers can shoot!
Wesley Springman was the top Heavy Gun Shooter, placing second in Group and third in Score, to finish first Overall in Heavy Gun class. Don Rabun was second in HG overall, with Eric Springman taking third in HG, edging Don Nagel on a tie-breaker (both Eric and Don racked up 14 Agg Rank Points). As noted above, Tod Sobey won the Light Gun Overall, with Donald Whitlock second in LG, and David Powley third. Notable other performances were Jeffrey Morten’s first place finish in LG Score, and Eric Springman’s outstanding Group shooting in Heavy Gun. Eric finished #1 in HG Group, with an impressively small 5.925″ Agg (that’s for ten-shot groups). And Sharon Ruben nailed the small group for the match, a mind-blowing 2.686″ on her second Light Gun (5-shot) target. For reference, one-quarter MOA at 1000 yards is 2.617″. Amazing.
Winning Rifles: 6mm Dasher Light Gun, 300 WSM Heavy Gun
Tod Soeby provided this equipment rundown for his Nationals-winning rifles.
Light Gun (6mm Dasher): Smithed by Greg Wahlstrom, Straightline Customs, in Ogilvie, MN. Greg also did the stock work and bedding. Action is a BAT “M” multi-flat, 8.5″-long, R-L-R dual port. Stock is a Shehane ST-1000. Barrel is 30″ Krieger 1:8″ twist, chambered as 6mm Dasher with 0.267″ neck. Optics are: Nightforce NSX 12-42X in BAT +20 MOA aluminum ring/bases.
Heavy Gun (300 WSM): Smithed by Clay Spencer. Action is BAT “L”, 10″-long, 2″-round, dual port. Stock is a Bruce Baer 5″-wide thumbhole, with custom rails by Greg Wahlstrom of Straightline Customs. The barrel is a Hart 1:10″ twist chambered in 300 WSM. Optics are: Nightforce 12-42X Benchrest model. Tod is not sure about the source of Picatinny rail and rings.
117 Shooters Competed at 2011 IBS Nationals
Overall, shooters commented that West Virginia’s White Horse facility was a nice range, and many folks hoped that other major events might be hosted there in the future. Despite the predicted hot, humid weather, there was a great turn-out for the event, with 117 registered shooters in Light Gun and 115 Heavy Gun Registrants. The match organizers at White Horse did a good job with such a large field of shooters. The excellent turn-out proves there is a growing interest in long-range benchrest.
