If I can get a 255gr LSWC to make 820 fps with 6.1gr Titegroup - and a 250gr Speer #4484 Gold Dot will behave similarly - and it still is less than the 14 kpsi SAAMI max for .45 Colt - why do I need to really hotrod this round? Sure, a .45 ACP 625 frame, etc, must be made to handle 21+ kpsi, so it is reasonable to expect to be able to exceed 900 fps handily and still be quite safe, but why? That lead round, at 900 fps, will travel the length of most NA fare - and that GD doubles it's surface area at 800+ fps incident in ballistic gel or brisket. My vote is for longevity.

Okay, I'll come clean. I had a myriad of Rugers over the years - .454 SRH; .45's in BH, Bisley BH, Vaquero, & RH - all gone now. Blame it on my first-ever-S&W - a 625-7 MG in .45 Colt - or it's 'spare' sibling, acquired a few years, a 625-6 MG. They are super - and, I still enjoy plinking with my .45 Colt loads - and I don't miss the Rugers. Maybe my avoidance of big thumpers came about after over 800 .454's from that SRH...?
