For practice and target, if use the Missouri Bullets 225 Flathead over 5.2 grs. of HP-38 for 800 fps in a 5" 1911. For defense, I use the 230 gr XTP over a fairly stiff charge of HS-6 (9.0) grs. This is from the 45 ACP +P Hodgdon used to publish. Max in that data was 9.3 grs. of HS-6 with a 230. That being said, 98% of my 45 ACP shooting is with the 225 Cast load at 800 fps.
