New .204 Ruger, .300 Whisper, & .223 Rem Ammo from Black Hills

Black Hills has announced three new types of loaded ammunition for 2012. (This is all-new factory ammo, not commercial reloads.) The first caliber is the .204 Ruger. The new round uses the 32gr Hornady V-Max™ projectile that has proven to be one of the most accurate and effective bullets available for use on varmints.

125gr and 220gr (subsonic) Options in .300 Whisper
The second is the .300 Whisper. This cartridge is the brainchild of JD Jones of SSK and has been around a long time as a proven wildcat cartridge. This versatile 30-caliber cartridge is designed primarily for use in M4/M16/AR-15 family of rifles and allows for use of a wide weight range of projectiles. Initial Black Hills loads for this cartridge are a 125 grain load that essentially duplicates 7.62×39 ballistics, but with far superior accuracy, plus a 220 grain Sierra MatchKing at subsonic velocity.

New 69gr SMK load in .223 Rem for AR15s
For use in AR15s with 1:9″ twist barrels, Black Hills’s customers have asked Black Hills to provide factory ammo loaded Sierra’s highly accurate 69gr MatchKing. In response to customer demand, for 2012 Black Hills will be offering the 69gr SMK loaded to 5.56mm pressures and velocities in military specification brass. In this new ammo, Black Hills has utilized modern temperature-stable, flash-suppressed propellant.

Larry Racine’s Switch-Barrel System

Larry Racine is a respected gunsmith based in New Hampshire. He is also a two-time member of the U.S. Palma Team, and a five-time New Hampshire State Highpower rifle champion. Larry, who runs LPR Gunsmithing, has developed a brilliantly simple means of switching rifle barrels with an ordinary spanner or open-end wrench. With this set-up you can switch barrels in the field in seconds without the need for a barrel vice.

For most barrels, Larry mills a hex with six flats on the end of the barrel. This allows a shooter to change barrels quickly at home or on the line with a simple box-head wrench or a socket wrench. Larry says: “You don’t even have to take the barreled action out of the gun. Just set the buttstock on the ground, between your feet, put a wrench on it, hit it with the palm of your hand — and off comes the barrel.” For barrels fitted with a muzzle brake, Larry has a slightly different system. He mills two flats behind the brake so you can use an open-end wrench to do the job.

With either a hex on the end, or two flats for a brake-equipped rifle, the system works with any medium- to heavy-contour barrel with a muzzle-diameter of at least 0.700″. This will even work for high-power rigs using clamp-on sights or bloop tubes. Larry explains: “A lot of us here in New England use clamp-on front sights. The barrel will be turned to 0.750 for the sight, with the hex on the end. A bloop tube can go right over the end, no problem.”

Larry has used this system over the past few years to win a number of matches. In one 600-yard 3 by 20 prone match, Larry used three different barrels, with three different chamberings, on the same Savage rifle. Larry changed the barrels on the line.

Larry was able to do this because the system has little to no loss of zero from one installation of a given barrel to the next installation of that barrel. This lets the shooter start the match with confidence that the first sighter will be on paper. Larry reports that the simple system works great: “To date we have used this system on Savage, Remington, Winchester, RPA, and Nesika actions.”

Racine’s system is very affordable. If Larry does the chamber work on your barrel he charges $45.00 extra to mill a hex or two flats on your barrel. If you only want the hex or flats done, Larry charges $55.00. For more info, visit LPRGunsmith.com or call Larry at (603) 357-0055.
