I sold my second Bisley, which was gonna become a specialty six-holer for the .45ACP cartridge. I believed that having a suitably small powder capacity would make for an excellent target gun. Never got to test the premise, and I sold that gun unfired.
The .500 started as a .357 Bisley and I did shoot that as originally supplied. I prefer my other .357s, Colts, S&Ws and a coupla Freedom Armses. Those last two are sweeeet.
the 353 is a five-holer with
massive cylinder walls. By grinding up uranium and matchheads and mixing them with political cartoons, I sent 180s out that muzzle at 1900 feet per second. Now THAT is a bear load in a subcaliber.
Addendum. I wanted a cylinder for the 353 in .454 Casull necked down to .357 ... was gonna call it the Double Magnum or Sheepshifter (a silhouette reference). Nobody would make me one because that Freedom steel eats up tooling.
