H110 should not be reduced below listed start load, and that is more FPS than you are looking at wanting. Lil'Gun is also above your desired velocity.

Longshot looks like it will get you where you want to be, and maybe Titegroup.

Good question.

Here's what I could find:

.45 Colt case holds 13.3gr of Trailboss (NOT load data!)

.45 Colt data from hodgdon.com

250 GR. CAST LRNFP IMR Trail Boss .452" 1.600" start = 4.5 606fps 8,800 PSI max = 5.8 727 12,700 PSI

IF the IMR people use their own formula then it's probably not possible.

This report says the 5.8gr load "pretty near fills the .45 Colt case to volume capacity." http://www.gunweek.com/2005/feature0901.html

No.7 as you stated, or No.9 would get him where he wants to be and do a good job of filling the cases and are well within pressure limits.
