Joe 45look in alliant for powder pistol reloads. They have loads for 185gr to 230gr +P loads

KLN357Accurate's website used to have +P data using #5 and #7.

If they don't let me know and I'll put it up!

These are heavy loads that worked well in one Colt Gold Cup and one ATM Hardballer. They should be worked up from at least 5% less than the charges shown. BUT these loads caused NO PROBLEMS in the two pistols they were tested in, both of which had 22-pound recoil springs and shock buffers installed first!
I developed a "+P" load for my Colt Gold Cup using the 452423HP Keith cast hollowpoint semiwadcutter bullet which weighs 230 grains. It was loaded in cut-off .45 Win. Mag. cases, and consisted of 7.3 grains of Herc. Unique, Federal LP primers. V @ 10' from the muzzle was 998 FPS. Accurate, too!
Another +P I have used is the 230-grain Hornady XTP bullet with 10 grains of HS-6 powder, also in the Win. Mag. brass cut off to .45 ACP length. Federal LP primers. MV on this load is close to 1000 FPS.

Hogdon lists some in their older manuals, but 6.0 grains of Titegroup with a 200 grain swc and federal large pistol primers in starline brass give me 1075 fps in my 1911 with no pressure signs, I did install a recoil reducer spring from Sprinco as well though.
Work up slowly. Good luck.
