  1. The .460 Rowland a Semi-Auto Magnum

    The .460 Rowland conversion is available for most popular .45 ACP pistols, (Glock,XD,1911, etc). The .460 Rowland is meant to offer .44 maa type ballistics in a .45 ACP pistol. From a 1911 conversion it will push a 185 grain bullet at 1575 feet per second offering over 1000 ft/lbs. The 240 grain can be pushed to 1350 and a 255 hardcast will move out at 1300fps.

    You don't need different magazines. The casing is 1/16" longer than a .45 ACP to prevent firing in a normal .45. The bullets are...
  2. The .357 SIG

    The .357 SIG wasn't the first bottleneck handgun cartridge. In the 1960's Winchester necked the .357 Magnum down to to .257.Then the 9x25 Dillon came along in 1988 by necking the 10mm Auto down to .355". Finally in 1994, SIG Sauer and Federal with a joint venture, shorterned and necked down the 10mm to create the .357 SIG. Some think you can form it using .40 S&W brass, but the .40 is 0.009" shorter than the .357 SIG.
    The idea of this cartridge was to try to match the 1450 feet per second...
  3. The .45 GAP

    Created by Ernest Durham in 2002, an engineer with Speer at the time. He did so at the request of Glock to create a cartridge with equal power to the .45 ACP, but be stronger in the neck area to lower risk of blow outs there, and also let it fit in the 9x19 & .40 S&W sized handguns. Of course GAP stood for "Glock Auto Pistol". No sooner than this cartridge hit public knowledge we started hearing "it will be gone in 10 years". I laughed just last week as I was in a local gun store and heard...
  4. 10mm AUTO The Cartridge, The Myth, The Legend

    The 10mm Auto, it almost vanished into obscurity. The brainchild of Col. Jeff Cooper who set out to make a flatter shooting cartridge than his beloved .45 ACP. He wanted it to be able to push a 200 grain bullet to 1200 feet per second, and it was achieved by shorting a .30 Remington case, blowing out the walls so it would accept the bullet from the .38-40 Winchester, a .400" bullet. Basing a pistol off the CZ75 design, the Bren-Ten was born, but it came at a price. $500 was a lot of money in...
