Thanks for the quick reply. I'll stick with the 230gr JFPs until I can test the 255s. Had a problem with the Buffalobore +P 255gr LFP .45 ACPs in a Kahr CW45. Turns out the Kahr has a real short throat. Had the Kahr throated -- problem solved. Pretty sure Buffalobore uses the same 255 LFP in both the 45 +P and 45 Super ammo, so it may be same issue. I'll check the 255gr LFPs for function and report back.
