45 colt rifle for subsonic use

[winmdl98]

I used R-P nickel cases, WLP primers, 6.0 gr of Titegroup, 300 gr Lead Truncated Cone bullet, bullets seated backwards to 1.400" Overall Length, there was .125" of exposed bullet out of the mouth of the brass. They chrono'd 933 FPS, muzzle flash was less that 2" when shot at the indoor range, rifle was a Marlin 24" Cowboy 45. Incredible low recoil. I did not have a 22LR to compare it to at the time.
Hope that helps.
