Interesting thread! I've experimented with the 460 Rowland in years past, still have a lot of the brass on hand, plus several assorted boxes of handloads. But my recent forays into the .452" family have led me to purchase another 625-3, as well as some Starline 45 Auto Rim brass for it. I've long heard that 45ACP power levels can be boosted safety in this modern gun, and as it happens, I also recently bought a Ruger Blackhawk Convertible in 45ACP/45 Long Colt, so I have two VERY strong platforms to experiment with when it comes to launching 45ACP boolits.

Anyone else experimented with hot 45 Auto Rim loads? I'm thinking with new brass I can safely approach 24-26,000 PSI loads, possibly even higher, in a pair of guns designed to take a lot more pressure than that.

What say the form folk? Any daredevils here? ;-)
