Every shooter needs to get his or her start someplace. We applaud the NSSF First Shots program that brings new shooters into the fold. If we want to “stem the tide” and resist pressures to close gun ranges and limit firearms use, we need to get new people involved in the shooting sports. And the first step in that process is getting first-timers to the range. Around the country, First Shot Seminars provide free instruction by trained firearms instructors, with guns and ammo provided at no charge to participants. The free First Shots program teaches newcomers firearms fundamentals, safety, and local regulations in a classroom setting, followed by a live-fire session with certified instructors.
Ever wondered how a modern, jacketed bullet is made? Thanks to Berger Bullets, here’s a short video clip that shows how bullets are crafted. In this short sequence filmed at Berger’s factory, you can see machinery that forms the jacket, inserts the core, and then forms the final shape.
This handsome Paterson revolver, the earliest known, factory-engraved Colt, sold for remarkable $414,000 at an April 2015 RIA auction.
Gun prices climbed into the stratosphere last month during the 2015 April Premiere Firearms Auction conducted by the Rock Island Auction Company (RIA). The most expensive gun at auction was an historic Colt Paterson, the first-ever factory-engraved Colt handgun. Complete with the original fitted factory case with various accessories, this Paterson inspired a bidding war that saw the price rise to a stunning $414,000. That is an amazingly high price for a gun that was not owned by a well-known historic personage. Generally, to command a price in the multiple hundreds of thousands of dollars, a gun must have a significant historic provenance — such as having been owned by a legendary figure such as Billy the Kid or Wyatt Earp.
It seems like prices continue to rise every year at auctions of historic and collectible firearms. At RIA’s April Premier Auction, the total sale value of the auctioned guns topped $11.6 million. Remarkably, a first-year production Colt Python (serial #170) sold for $17,250! That makes this Editor regret not having acquired an early model Snake decades ago.
Montana sportsmen can now legally use suppressor-equipped firearms when hunting game (provided the silencer was obtained in compliance with Federal laws). Montana Governor Steve Bullock recently signed HB 250, a new law allowing the use of sound moderators (aka silencers, cans, or suppressors) when hunting all types of game animals in the state. The enactment of this legislation immediately brings Montana in line with the 34 other states that currently allow the use of suppressors for hunting wildlife. Note, in all those states, you must still comply with federal regulations governing ownership of silencers and obtain a tax stamp for each suppressor you own.
The 9th Annual Eastern CMP Games and Creedmoor Cup Matches will be held at Camp Butner, North Carolina, May 1-10, 2015. The Eastern CMP Games run May 1-5, while the Creedmoor Cup Matches take place on May 6-10. All interested shooters are invited to participate in this popular event, which includes: Rimfire Sporter Match, M16 Match, M1 Garand Match, Springfield Match, M1-Carbine Match, Vintage Military Match, Modern Military Match, Vintage Sniper Match, Pistol Matches and more. New for 2015, the CMP will be hold a .22 Rimfire EIC Pistol Match.
The Vintage Sniper Match is a two-person team match, utilizing scoped rifles from the Korean War, World War II or earlier, upon sandbags. Teammates take turns as both shooter and spotter.
Well, it appears that youth and skill CAN triumph over “old age and treachery” — at least in the world of IBS benchrest competition. Here’s a feel-good story that should give us confidence in the upcoming generation of new shooters.
A month ago, Henry Miller won the IBS benchrest match at Dunham’s Bay, New York. Henry shot a .2698 Aggregate to top 21 other shooters. That sounds like a standard headline for most any benchrest event, doesn’t it? In the case, however, it was rather exceptional. You see, Henry, the son of long-time benchrester Scott Miller, is just eleven years old. It was an impressive performance by the young man — conditions for the March 22nd match were difficult. In fact, only two shooters finished under .300 for the 100-yard, five-target average. Scott Miller introduced son Henry recently to the world of benchrest competition. In addition to Dunham’s Bay, young Henry has shot at Pine Tree Rifle Club in Johnstown, New York and at Bell City in Connecticut. By the way, Henry beat the Euber brothers (both Hall of Famers) and other veteran shooters many decades older than he. Well done, young man!
Most competitive long-range shooters weigh powder charges for their handloads. Some even use ultra-precise magnetic force restoration scales to load to single-kernel tolerances. But is weight-based measuring always the best way to fill a case with powder? Another option is volumetric charging. This method fills a precisely-sized cavity with powder and then dumps the charge into the case. A Harrell’s rotary powder measure works this way, as does the sliding powder filler on a Dillon progressive press.
For long-range applications, most people believe that precise weighing of powder charges is the best way to achieve optimal accuracy and low ES/SD. However, those short-range Benchrest guys do pretty darn well with their thrown charges, at least at 100 and 200 yards.
Our friend Dennis Santiago recently observed something that made him scratch his head and wonder about weighing charges. His AR-15 match rifle shot better with volumetric (cavity-measured) charges than with weighed charges dispensed by an RCBS ChargeMaster. Here’s what he reports:
Cavity vs. Dribble (Dennis Santiago Report) I had the chance to compare nominally identical ammunition loaded two ways. These were all .223 Remington match loads using 77gr Sierra Match Kings over 23.4 grains of Hodgdon Varget. Same gun. However I loaded some ammo with charges dispensed with a Lee cavity-style powder measure while other rounds were loaded with powder weighed/dispensed by an RCBS Chargemaster. The cavity-drop ammo (with powder dropped from the Lee unit) was consistently better than the weighed-charge ammo. I have no idea why…
So, ladies and gentlemen — what do you think? Why did Mr. Santiago’s volumetrically-charged ammo shoot better than ammo filled with weighed charges? What’s your theory? Gary Eliseo suspects that Dennis’s Chargemaster might have been drifting. What do you think? Post your theories in the comments area below.
In a revealing podcast, Pete Brownell of Brownells, the largest gun parts vendor in the world, provides some fascinating insights into today’s firearms industry. On Episode 122 of the AR-15 Podcast (see Podcast video below), Pete and Podcast host Reed Snyder talk about the growth of the firearm industry and the widespread popularity of guns in the USA. Looking back at the second half of the 20th Century, Pete speculates that the millions of GIs returning from WWII fueled the growth of competitive shooting and hunting. America’s love affair with guns has continued apace into the 21st Century. Now an estimated 39% of American households own guns according to a Gallup survey, and the NRA says the true figure is closer to 50%. Additionally, Pete and Reed talk about the changing face of gunsmithing. Pete notes that the tighter tolerances permitted by advanced tools have fostered new methodologies and improved precision in gunsmithing.
Here at AccurateShooter.com we tend to focus on highly-accurate (1/2-MOA or better), custom-built bolt-action rifles. But for home defense, deer hunting, or just having fun with the grand-kids, factory-built firearms serve their purpose. With that in mind, we wondered, “Just what are the most popular mass-production firearms these days?” Gunbroker.com, the biggest firearms auction site, has tallied the top-selling new and “previously-owned” firearms in various categories for all of last year. Here are Gunbroker’s “Best Selling Firearms” for 2014.
