Settled into a groove with my .45 ACP reloading, I've loaded at least 1000 rounds and sent them down range and have another 300 rounds on the shelf. I'm almost out of my first can of Win 231 and I'd like to try a new powder.
I'm loading .45 ACP, Winchester Small Pistol primers, Magnus 230 grain FMJ, mixed brass and shooting it out of a Taurus PT-145 with a 3.25" barrel.
I've found that 4.9 grains of Win231 fires and functions well. I can get 2" groups out of the gun if I do my job. Theres really no reason to experiment other than just because I can.
I don't have a chronograph (yet) so I'm watching for pressure signs in the brass. I shoot about 400 rounds a month through this gun so I know what feels normal too.
What powder should I try next?
