I don't know what the Max load is with CFE pistol with 230gr. jacketed in 45acp but I wouldn't be alarmed one bit of going to that level with a good plated bullet. "Most" plated bullet makers give up to 1200-1250FPS limit on their wares. Some go higher. For me that would be the limit I'd consider. You'll not reach anywhere near those numbers (unless you're a bit like me

) shooting "normal" 45acp rounds. More like 850-900fps, and for a lot of guys 900 is pushing the 1911. I mean, really, guys brag about getting over 2000fps shooting cast bullets in (name yer poison) rifle, but somehow that same cast bullet with a copper plating is somehow inferior to that. I ain't buying it. I've shot RMR 200gr. plated bullets in MY 45 well over 1200fps and NOTHING BLEW UP.......accuracy was fine and the bullets recovered (dug out of the bank I shoot into) were still intact with little damage. I don't follow the 4.8gr Bullseye, 5gr 231, standard mindset a lot seem to have, the 1911 45acp can be so much more than that. Everyone follows their own path, that's mine.
I should add that I have made some "adjustments" to my 1911.
