MUZZLE BRAKE INFLUENCE Regarding Dave Emary’s column in the April 2020 issue, “Boattail vs. Flat Base,” how does a muzzlebrake affect a boat-tail bullet’s trajectory? Wouldn’t the gas blow-by be reduced by allowing the propellant gasses to escape through the brake’s ports? Is this something that Guns & Ammo has tested before? Ted Schaffer Email All things being equal, a muzzlebrake or porting should improve things. The best solution is a barrel service like the one Magna-port offers (magnaport. com). However, this has drawbacks because you will get port erosion and other effects. There are no free lunches here. I also preferred minimum-spec’d barrels with ammunition loaded with fast-burning propellants to limit the muzzleblast. This is a great suggestion for more research using Schlieren photography. Stay tuned. — D. Emary…

Singer Model 1911A1, .45 ACP A rare and desirable Model 1911A1 pistol produced by the Singer Manufacturing Company realized an impressive $126,000, including premiums, at the May 29, 2020, Morphy Auctions sale. Only 500 of these 1911A1s were built by Singer during World War II. Singer 1911A1s are among the most sought-after arms of their type, and this particular specimen is in fine condition, all correct, and with about 85 percent of the original blue finish remaining. Singers are very evasive. It is believed that most went to the United States Army Air Corps (USAAC), and the attrition rate was quite high. For more information about this and future sales, contact Morphy Auctions, morphyauctions. com, or at 877-968-8880.…

RED DOT SIGHTS have taken over the optics world for good reason. They are durable, simple, effective, and have evolved so much that there are a couple of red dot categories: full-size and mini. Mini red dot sights (MRDS) continue to find their way into areas previously unimaginable. When the MRDS first arrived on scene nearly 20 years ago, some saw its immediate application on a pistol’s slide. Small enough to ride on top without adding any width to a pistol, such examples were also light enough that they didn’t negatively affect the slide’s operation, generally. Placing a small illuminated dot on a target also made accurate shooting much easier (as competition shooters already knew), but especially so for those with aging eyes. An MRDS doesn’t require the eye to…

RIFLE & OPTICS EDITOR Tom Beckstrand introduced Hornady’s 6mm Advanced Rifle Cartridge (ARC) to the Guns & Ammo’s digital audience with a YouTube video that immediately went viral on June 3, 2020. This was a carefully kept secret as the cartridge had been developed, standardized and adopted by a notable unit within the Special Operations community. This occurred before the existence of the cartridge was made public. For that unnamed unit, we’ve only been told that “the 6 ARC is a replacement for the 7.62 NATO for combat operations.” This is the second time that the announcement of a new cartridge was preceded by the military’s adoption; The first was Hornady’s .300 PRC announced on October 16, 2018. The Why Our enemies in the War on Terror have learned that…

AS EVIDENCED BY the “Cecil the lion” incident in Zimbabwe on July 2, 2015, there are few policies that evoke the reaction and controversy than hunters pursuing African game. Trophy photos on social media often spark outrage, boycotts, vitriol and sometimes death threats. Like many areas of debate today, emotional sentiment usually upstages fact. No matter where you stand on the issue of hunting, most can agree that the goal of wildlife policy regulations should promote the biodiverse and sustainable populations of indigenous species, and support conservation and habitat improvements. Originally, the Conserving Ecosystems by Ceasing the Importation of Large (CECIL) Animals Trophies Act (H.R. 2245) aimed to ban U.S. importation of sport-hunted trophies from three African countries: Tanzania, Zimbabwe and Zambia. Today, the bill still exists to both discourage…

PERHAPS I UNDERSTAND Victor Frankenstein. If you are intimately familiar with the AR-pattern rifle, carbine or pistol, there’s a sense of pleasure when you disassemble and reassemble the amalgamation of different parts and pieces — as long as it still works. I’ve been told that most gun owners who already have at least one AR-15 have turned to building their own than buying a new one; I can believe that. To learn how to do-it-yourself and be self-sufficient describes the current trends. For many of us, AR-15 builds will comprise some new components, while others are cannibalized from former projects. In the end, pleasure usually turns to pride as we cradle something near 7 pounds of modern art, the kind that sends anti-gunners into orbit when they try to understand…

Model 1892 “Henry” Rifle Before replica Henry rifles became available in Hollywood, the industry recognized the need for something that at least looked like a Henry, and that’s when the tried-and true-Winchester Model 1892 was pressed into service. By removing the forend and fitting the receiver with a dummy follower stud, a .44-40 ’92 made a passable Henry. Often, their receivers were even brass plated, or painted gold. Thus, these altered guns found their way into scads of Western movies and T.V. shows. Interestingly, there was at least one golden-age Western that actually used a real Henry. In the movie “Arizona” (1940), Jean Arthur gives William Holden an original Henry to take with him on a mission. As original Henrys chambered .44 rimfire rounds, and proper blanks were not available,…

SHOOTERS HAVE NEVER HAD IT SO GOOD when it comes to factory ammunition. The variety of ammunition sold is staggering. It used to be about all that was available was ammunition with a soft-point (SP) cup-and-core bullet and a few soft-point bonded bullets. All factory loads with the same bullet weight had about the same muzzle velocity, and choosing was simply a matter of deciding which brand you wanted. Now, there is a dizzying array of bullet types on the market, soft point cup-and-core, bonded, monolithic, tipped bullets of every type, specialized long-range, coated, and on and on. Numerous performance levels are now obtainable including light recoil, standard velocity, high performance and even AR specific, just to name a few. The quality of factory ammunition has never been better, either.…

“Sounds like you have been doing your homework as much of your data is correct.” EARLY COLT 1911A1 Q: I’m writing on behalf of a friend who received a gift of an unfired .45-caliber Colt U.S. Army Model 1911A1. It was covered in Cosmoline. The only thing done to the piece was the removal of the Cosmoline. The details associated with this Colt are the stampings, which are as follows: serial “ № 719XXX”; “UNITED STATES PROPERTY”; “COLT’S PT F.A. MFG HARTFORD CT USA”; “PATENTED APR.20.1897 SEPT.9.1902 DEC.19.1905”; “FEB.14.1911”; and, “AUG.19.1913”. There is a “P” stamped next to the magazine release, and the letters “CSR” are stamped just below the slide stop, behind the trigger. There’s another stamping of a “P” on the left side, on top of the trigger-guard,…

DRY-FIRE TRAINING is excellent for maintaining and improving our pistol skills. Mike Hughes, a former patent attorney, USPSA shooter and a contestant on “Top Shot,” founded Next Level Training in 2010. Hughes invented a professional-grade laser-training pistol that offered similar handling characteristics as a loaded pistol. The pistol features a “Shot Indicating Resetting Trigger,” hence the name “SIRT.” The SIRT Pro 107 replicates a full-size Smith & Wesson M&P pistol, and the SIRT Pro 110 resembles a Glock 17 or 22, two popular models among law enforcement agencies. Originally colored two-tone red and black, SIRT pistols are offered with red, green, pink or purple metal or polymer slides. These colors help to distinguish them from their live-fire counterparts. A credit to Next Level Training’s engineering, SIRT pistol dimensions are so…
