earplug Posted February 10, 2012 Share Posted February 10, 2012 I have been messing with my USPSA major PF revolver loads in my 1911. I'm not as happy with tossing brass all over the range and making metal parts slam back and forth. It is entertaining to shoot the beast since I took the Marvel 22LR conversion off after our bullseye league ended. Do any of you have any experience with what change to expect with power factor when comparing a five inch 625 and a five inch 1911? I'm guessing its a wash between the longer barrel and cylinder gap on the 625 and the shorter length of the 1911. I'm using a 230 grain cast bullet that gives me a 175 PF out of the 625 if it means anything. Link to comment Share on other sites More sharing options...
Blueridge Posted February 10, 2012 Share Posted February 10, 2012 I would hazard a guess of a loss of 30-50 fps in the revolver with the same load that you are using in the 1911. Link to comment Share on other sites More sharing options...
cas Posted February 10, 2012 Share Posted February 10, 2012 I load for like 12 different 45acp's, with the exception of my dads old Bullseye gun, they all get fed the same load which makes major in my well worn 625. My single stack loads are a good deal hotter than they need to be. lol Link to comment Share on other sites More sharing options...
71Commander Posted February 10, 2012 Share Posted February 10, 2012 I load for the Revo. I know it will be safe in the 1911. Reverse order would be iffy. Link to comment Share on other sites More sharing options...

71Commander Posted February 10, 2012 Share Posted February 10, 2012 I load for the Revo. I know it will be safe in the 1911. Reverse order would be iffy. I was referring to power factors, not danger as in Kaboom. Link to comment Share on other sites More sharing options...

kevinj308 Posted February 11, 2012 Share Posted February 11, 2012 My 230gr LRN load is 176pf out of my 1911 and 169pf out of 4" 625, so probably close to a wash out of a 5" 625. Link to comment Share on other sites More sharing options...
pskys2 Posted February 11, 2012 Share Posted February 11, 2012 (edited) With a Match Grade 1911 Barrel I usually see about 30 f/s more than with my 5" Revo. BUT you can see 30 f/s, or more, between identical guns also, so you just never know. Safe bet is to start with working up the load in the Revo and then checking it in the 1911.
