The Weapons System Technology Analysis Center (WSTIAC), part of the U.S. Department of Defense (DoD), recently conducted a comparison test between standard primers and lead-free primers. The test procedure, along with the surprising test results, are discussed in the WSTIAC Journal (Vol. 11, No. 2).
Key Findings of the WSTIAC Primer Study Were:
1. Lead-Free primers suffered from significant delays in ignition.
2. Lead-Free large rifle primers had a “a much larger variation in peak blast pressure” than did lead-based large rifle primers.
3. Field tests showed 7.62×51 rounds loaded with lead-free primers to be less accurate than rounds loaded with lead-based primers.
4. So-called “match-grade” primers were NOT always more consistent in pressure than standard primers.
Russian Lead-Free Primers Tested
WSTIAC scientists did some pretty sophisticated testing, measuring the blast waves of lead free primers vs. standard primers. The lead-free primers, denoted as DDNP for their “Diazodinitrophenol” active ingredients, were matched up against commercially-available primers containing lead. Eight models of widely-used, lead-based primers were tested along with two DDNP-based Russian-made primers, a large rifle primer (model KVB-7E) and a small pistol primer (model KVB-9E). Brief field tests were also conducted with large rifle primers in loaded ammunition. Testers measured primer ignition times, bullet muzzle velocities, and accuracy on 200m targets.
Lead-Free Primers Were Less Reliable, with Less Uniform Pressure
While you’ll need to read the study to understand the full results, in a nutshell, the DDNP (lead-free) primers proved somewhat less reliable than standard primers. The study observed: “The most obvious difference between the lead-based and DDNP-based primers was a perceptible delay between firing pin strike and ignition in 15 of 19 shots with the DDNP-based primers (and one misfire); in contrast, there were no misfires or perceptible delays in ignition with the lead-based primer.” The scientists theorized that: “The delay in ignition in 6 of the 10 shots with the DDNP-based primer suggests that this primer is at the low end of strength needed to reliably ignite 46 grains of an extruded powder.” The study also noted that: “DDNP-based KVB-7E has a much larger variation in peak blast pressure than other primers.”
Lead-Free Primers Were Less Accurate in 7.62×51 Ammo
One very interesting finding related to accuracy. In field tests, 7.62×51 ammo loaded with lead-free primers was tested against ammo with lead-based primers (other components were identical). At 200m, the average 10-shot group size of 7.62×51 ammo with lead-free primers was 2.5 MOA vs. 1.8 MOA for ammo with lead-based primers. That 0.7 MOA difference may well be meaningful (though we’d like to see the test repeated with multiple 10-shot groups, fired from a more accurate rifle). For precision shooters, this is a provocative finding because it suggests that a change in primer type, by itself, may have a dramatic impact on accuracy. The scientists surmised that: “ignition delay is the most likely cause of the larger average group size.”
“Match” Primers Are NOT Always More Consistent
One surprising collateral finding in the study challenges the widely-held notion that “Match Primers” are better, at least when judged by pressure uniformity. “Table 1 shows average peak pressures along with standard deviations from the mean for the primers in this study…. There are significant differences in the standard deviations observed for different primer types, and it is notable that so-called ‘Match’ primers are not always more consistent than non-match primers.” Readers should look at the bottom right of Table 1 below. Note that, as a percentage (%) of total pressure, the non-match CCI 450s have a significantly lower SD than the “Match” Fed 205m primers. On the other hand, the Federal 210M and 215M “Match” primers ARE more uniform in pressure than the non-match CCI Large Rifle primers.
ABSTRACT: Comparing Blast Pressure Variations of Lead-Based and DDNP (Lead-Free) Primers
This article describes the blast pressure waves produced by detonation of both lead styphnate and diazodinitrophenol (DDNP) based firearms primers measured with a high-speed pressure transducer located at the muzzle of a rifle (without powder or bullet). These primer blast waves emerging from the muzzle have a pressure-time profile resembling free-field blast pressure waves. The lead-based primers in this study had peak blast pressure variations (standard deviations from the mean) of 5.0-11.3%.
In contrast, lead-free DDNP-based primers had standard deviations of the peak blast pressure of 8.2-25.0%. Combined with smaller blast waves, these large variations in peak blast pressure led to delayed ignition and failure to fire in brief field tests.

The IBS 600-Yard Nationals was held this past weekend at the Midwest Benchrest Range in Yukon, Missouri. There was a good turn-out for the match, with 70 Light Gun (LG) entries and 68 Heavy Gun (HG) entries from all over the USA. Despite tough conditions (high winds on Friday, wicked mirage on Saturday), the top shooters turned in some impressive performances, including a 16-target average group size of 2.327 inches by overall Two-Gun Winner Sam Hall of North Carolina. No one was surprised to see Sam, a multi-time 600-yard Champ, come out on top. When he’s on his game, Sam’s hard to beat.
But the big story of the match was the superb shooting of Ryan Hunt from Missouri, a relative newcomer to the 600-yard benchrest game. Ryan finished second overall in the Two-Gun after finishing second in Light Gun (LG) group, third in LG score, and third in Heavy Gun (HG) group. Ryan’s average group size, for the entire match (both LG and HG) was 2.629 inches. That’s amazing marksmanship for a rookie… using a borrowed rifle!
Hunt Makes the Most of “Loaner” Rifle
What makes Hunt’s runner-up finish even more impressive is that, in both LG and HG, he used a borrowed gun, a 6mm Dasher in a new, 5″-wide Precision Rifle & Tools stock. Now get this — the very first time Ryan shot that gun was the day before the Nationals! Ryan told us the 5″-wide stock really tracked well, allowing him to shoot fast and accurately. Will we see more extra-wide stocks in Light Gun in the future? Ryan Hunt thinks so: “I think 5″ is the way to go. That’s all I’ll be shooting next year. The extra width really makes a difference in the way the gun tracks. You don’t have to worry about rolling or hopping. Just pull the trigger, slide her back and you’re on target. The biggest benefit from these 5″ stocks is that a Light Gun’s going to track like a Heavy Gun. When the mirage picks up, instead of following the dot, you can just trust the gun, the way it’s tracking. It really paid off last weekend.” It’s worth noting that Ryan did not use the old standby powders, Reloder 15 or Varget. In his Dasher, Ryan loads IMR 8208 XBR powder with Spencer bullets.
Sam Hall with his Heavy Gun
Match Winner Sam Hall, like most of the top performers at the 2011 Nationals, shot a 6mm Dasher in both classes. But unlike Ryan Hunt, Sam used a “true heavy” in HG class. Sam’s mammoth Heavy Gun, dubbed “Black Max”, is featured in a Gun of the Week Article in our archives. You can see Sam practicing with this rig above. Sam hauls out his “heavy artillery” once a year for the Nationals: “This rig won’t see daylight again until the next Nationals.” In Light Gun, Sam used the same 17-pounder he’s used to win previous championships. It features a BAT action, Krieger Barrel and Shehane ST-1000 fiberglass Tracker stock. Sam shoots Berger bullets with Alliant Reloder 15 powder.
Tough Conditions Both Friday and Saturday
Sam told us: “All eight LG targets were shot Friday. And the Heavy class shot all eight on Saturday. Friday had winds of 13 to 18 mph with gusts up to 25 mph. Saturday was less windy, but was switchy. Mirage was some of the worst I’ve ever encountered. These conditions caused vertical groups.”
We asked Sam if he had any special strategies for the match: “My only strategy was to make sure I got my sighters right. Last year I misjudged some sighters on a gong. I thought I was centered but I was actually way high and right. I ended up shooting a small group, but the score was really bad. This year I made sure I knew where the sighters were actually hitting.” You can learn more about Sam and his rifles in a Gun of the Week Article from our archives.
Dashers and Cut-Rifled Barrels A quick glance at the above equipment list for the Top 10 Two-Gun finishers, reveals the winning formula: 6mm Dasher in a cut-rifled barrel. Eight of the Top 10 competitors shot 6 Dashers in both classes, while another shot a 6 Dasher in HG and a 6 BRX in LG. That’s “Dasher Dominance” for sure. Among the barrels, cut-rifled tubes from Bartlein, Brux, and Krieger were favored by most of the top shooters. It’s hard to argue with success.
Shiraz Balolia has recently been appointed as Captain of the U.S. F-Class Open Rifle Team. Balolia served as Vice Captain of the previous team and was one of eight American shooters at the last World Championship held in England in 2009. He was also one of four shooters in the International Team matches in England where Team USA won the Gold Medal. The step up from Vice Captain to Captain brings new responsibilities, but Balolia told us he accepts his new role “with honor and a fierce passion to lead the team to gold in the 2013 World Championship”.
USA Will Host 2013 F-Class World Championship
With the 2013 F-Class Championship being hosted by the United States for the first time ever, Balolia and the U.S. team are determined to win the Gold Medal on home soil. Team tryouts commenced in 2010 and will continue until the complete Development Team is selected in early 2012, from which the main 2013 team will be chosen. Balolia added: “I am excited to have been given the opportunity to lead this team into the next World Championship. The shooters we have are absolutely incredible, and everyone has a single goal in mind… and that is to Win!”
2013 F-Class World Championship | Raton, New Mexico (USA) | August 23-27, 2013
The next F-Class World Championship will be held in Raton, New Mexico, from August 23 to 27, 2013. This will be the fourth F-Class World Championship and first time it is being held in the United States. Previous F-Class World Championship venues were:
2002 – Ottawa, Canada. Won by the USA.
2005 – Bloemfontein, South Africa. Won by South Africa.
2009 – Bisley, England. Won by Great Britain.
As you can see, historically, home teams have won in the past two events. This bodes well for Team USA’s chances in 2013.
U.S. F-Class Championships Will Precede Worlds at Raton
Preceding the World Championship, the 2013 US F-Class National Championship will be held from August 18 to 22, 2013. All F-classers are welcome to register. With the U.S. and World Championships scheduled back-to-back, August 2013 should offer the most memorable 10 days of F-Class competition ever conducted in North America.

An 1836 Colt Paterson Revolver (with accessories in box), sold last month for $977,500 at a Texas auction. This is believed to be a new world record for the sale of a single American firearm. The very rare, ivory-gripped Texas (Holster Model No. 5) Paterson Revolver was part of the Alfred (“Al”) Cali Collection of Colt firearms. The revolver, with a 9-inch barrel and attached loading lever, is the finest known surviving example of Samuel Colt’s first revolver, produced by the legendary gunsmith in Paterson, New Jersey in 1836.
Colt Purchased by Silicon Valley Zillionaire
The 1836 pistol, one of the earliest generation of Colt revolvers, was purchased by an unidentified West Coast collector, a Silicon Valley mogul. The gun was sold September 18 as part of Greg Martin Auctions/Heritage Auctions’ Signature Arms & Armor Auction in Dallas. “There are certain collectibles that transcend genre, period and form and exist simply as great works of art,” said Greg Martin, “and clearly this supremely beautiful firearm is such a thing. The nearly seven-figure final price realized proves just how great a piece this is, and well worthy of being the world record-holder. This is as desirable… as any piece I’ve seen in more than 40 years of buying and selling the very best firearms in existence”.
Two More Boxed Colt Revolvers Sell for Over $800K Each
A pair of Colt revolvers tied for the September auction’s second most valuable lot, both realizing jaw-dropping $805,000 prices. The first was an exceptional historic, cased, engraved and presentation-inscribed Colt Model 1861 New Model Navy Revolver. The second was an historic, cased Gustave Young-engraved and ivory-gripped Colt Third Model Dragoon Revolver, inscribed ‘Colonel P.M. Milliken”. Both these guns were from the Al Cali collection, like the record-setting 1836 Paterson.
SOCOM, the U.S. Special Operations Command, is going silent in a big way — purchasing $23.3 million worth of suppressors (and adapters) from Surefire, LLC of Fountain Valley, California. The huge contract, for an indefinite quantity of sound suppressors, suppressor adapters, blank firing adapters and training adapters, was awarded by officials of the Naval Surface Warfare Center — the primary solicitation center for U.S. Special Operations Command — as part of the Family of Muzzle Brake Suppressors (FMBS) contract.
This is good news for SureFire, which has expanded its product line from durable, high-output lamps to a wide variety of tactical hardware. It was a major coup for SureFire to secure a large part of the FMBS contract. According to Surefire: “The FMBS solicitation was the most comprehensive modern suppressor evaluation conducted by the U.S. military to date. [Suppressor systems were] subjected to prolonged testing on a variety of firearms platforms. SureFire suppressors were chosen based on test criteria such as: Reliability, Sound Reduction, Accuracy, Point of Impact Shift, Endurance/Durability, and Operational Suitability. While these requirements reflect the suppression needs for firearms including the MK13 sniper rifle, the United States Marine Corps is already employing SureFire’s FA762SS suppressor system on every M40A5 sniper rifle.”

Results are in from the inaugural IDPA World Championship held September 21-24, at the Universal Shooting Academy in Frostproof, Florida. There were 387 competitors from 18 different countries. Triple-digit temps, high humidity, rain, and muddy conditions made the 22 challenging stages even more difficult.
Champions were named in each of IDPA’s five divisions, based on elapsed time and penalties for “points dropped”. Robert Vogel topped the field of Standard Service Pistol (SSP) shooters, with a superb 248.29 score — the best score for the match and over 40 points better than any other SSP shooter. Robert was also the High Scoring Law Enforcement competitor. In the video below, Robert demonstrates the skills that carried him to victory in Florida.
In other classes, James McGinty became the first-ever World Champion in the Enhanced Service Pistol (ESP) Division by scoring 283.31 with his STI 2011 9mm. Glenn Shelby, with a score of 299.48, took the Custom Defensive Pistol (CDP) Division shooting his Wilson CQB. Among the wheelgunners, Jerry Miculek shot a modified .45 ACP S&W Model 625 to win the Enhanced Service Revolver (ESR) Division. Miculek hammered through the tough stages during the monsoon-like weather, scoring 411.79. In Standard Service Revolver (SSR) Division, Craig Buckland led the way with a 426.9, using his S&W Model 19. Other notable competitors were: James Myers (Most Accurate Shooter); Tom Yost (Top Senior); and Tierrani Hendrix (High Lady).
Portrait Photographer Lindsay McCrum’s new book, Chicks with Guns, is drawing welcome attention to the growing number of women who own firearms for target shooting, hunting, personal defense and collecting. [Editor: Over 15 Million American women are packing heat according to Msnbc.com.]
The book’s intent is described this way: “Because gun ownership and shooting cut across class, age, occupation, background and geography in America, guns are resolutely democratic. And the women depicted in ‘Chicks with Guns’ represent this variety. They reside in all regions of the country, come from all levels of society, and participate seriously in diverse shooting activities. From policewomen to hunters, ranchers to competition shooters, the collection of portraits in ‘Chicks with Guns’ defies stereotypes often associated with aspects of the popular culture of both guns and women.”
McCrum’s photographs tell a powerful story, just as these statistics do: Participation by women in target shooting has increased 46.5 percent from 2001 to 2010 and in hunting by 36.6 percent in the same period, according to the National Sporting Goods Association. In an NSSF survey of firearms retailers, 61% of respondents saw an increase in female customers in their store in 2010 over 2009.
Other evidence, too, such as the strong turnouts by women in concealed carry classes nationwide and in NSSF’s First Shots seminars, helps confirm this trend. (First Shots introduces newcomers to target shooting by providing both a classroom overview and supervised live-fire experience.) This is nothing new to the hunting and shooting community, but we think the compelling photographs in “Chicks with Guns” will bring the trend to life for those less familiar with our traditions and our pastimes.
Editor’s Comment: I wouldn’t rush out to buy this book for your coffee-table, though it might make a nice gift for a lady shooter in the family. I’ve looked through the book. The photography is professional, but overall, mostly static and uninspired. I’d give it a B+ grade. This book wouldn’t have received much media attention but for the somewhat controversial subject matter and the catchy title. Still, ‘Chicks with Guns’ presents female shooters in a positive light, and that’s a good thing.
The best action pistol shooters on the globe are heading to Philippsburg, Germany next September. Germany was chosen to host the 2012 World Action Pistol Championship (WAPC). This event takes place every other year — Australia hosted the last WAPC in 2010. Phillipsburg, site of Germany’s largest indoor/outdoor Shooting Range, is roughly 23 miles from Heidelberg. The Schiessanlage (shooting range) Philippsburg has previously hosted IPSC German and European Championships.

The format of the World Championship is very similar to that of the Bianchi Cup; everything from the courses of fire to the evening activities. Each year, the host country determines how many shooters will represent each country from the various divisions (Production, Open, Metallic). Once that has been decided, scores from the two previous Bianchi Cups will determine who represents the United States. Competitors can also receive an invitation to be part of a Ladies, Senior, or Junior team.
At the most recent (2010) WAPC in Australia, Team USA dominated the competition. Amazingly, Americans Doug Koenig (1920-188X), Carl Bernosky (1920-181X), and Bruce Piatt (1920-177X) all shot “perfect” 1920 scores to finish first/second/third. We know the Europeans have been training hard, and we expect tough competition for the Americans next September in Philippsburg.
Smith & Wesson is replacing its President/CEO. This comes after Smith & Wesson stock hit rock bottom last week, trading at $2.49 per share, a 52-week low. Smith & Wesson Holding Corporation (NASDAQ: SWHC) today announced that P. James Debney has been appointed President, Chief Executive Officer, and a member of the Board of Directors, effective immediately. The company said the executive reshuffling was done “in accordance with the company’s comprehensive management succession planning process.” Debney previously served as Vice President of Smith & Wesson Holding Corporation and President of the company’s firearm division. Debney will replace former President/CEO Michael F. Golden, who will continue as a member of S&W’s Board of Directors.
According to the Outdoor Wire: “The remaining term of former President and CEO Michael F. Golden’s employment contact has being bought out by the company, but Golden will continue as a member of the Board of Directors[.] Golden’s contract is expected to impact the company’s current quarter earnings per share by as much as two cents, with the gross numbers to be included in the quarterly 10-Q set to be released after the close of the stock markets today.” Smith & Wesson stock, as of the time of this Bulletin release, is trading at $2.58 per share, gaining back a bit from the $2.49 low on Sept. 23, 2011.
