I have a YHM cobra M2 (.45) in on the way, and I was wondering if anyone has tried to put a .45 can on a 300 whisper (sub sonic loads only). Is it quiet? Not quiet? Exploded in your face? Any experience or advice out there?
Thanks!
Thanks!
According to QuickLoad, the muzzle pressure of a 220gr at 1100fps from a 10" .300 Whisper using H110, should have "about the same" muzzle pressure as a 230gr .45ACP from a 5" barrel using Unique, IE 4000 psi +/- 500.
