CAUTION: The following post includes loading data beyond currently published maximums for this cartridge. USE AT YOUR OWN RISK. Neither the writer, The Firing Line, nor the staff of TFL assume any liability for any damage or injury resulting from use of this information.
Even though the load below is within limits, I am still putting up the disclaimer...
The powder for hot .45 ACP is AA#7.
From the Accurate Arms loading manual, 11.0 grains is the maxload for a 230 grain bullet, and it exceeds 1000 FPS. I found the accuracy at 10.7 grains.
Yes, in fact I do have a 454... in more ways than one.
