Just found one very interesting load, listed for 45 LC, with 300 gr Speer SP jacketed bullet and with AA No 9: http://www.accuratearms.com/loaddata_caliber_handgun_standard_45cal.htm , go to 45 Colt 30 Cup
The top load is 18.8 gr, and velocity 1264 fps at 29,200 CUP. But, the one that intrigued me is starting load 16.9 gr and (calculated) velocity 1138 fps. I would guess that the pressure is in low 20 ksi range. Anybody has QuickLoad to calculate the pressure with 16.9 gr of AA No 9?
Despite just bit more than 1100 fps, this one is still powerful load, but with pressure slightly above top load for 45 ACP. The result should be lower muzzle blast and recoil than most other heavy loads with 300 gr bullets for 45 LC, especially in 44 Magnum. I would say that this could be a very useful load in a backup revolver where the shooter wouldn't suffer from ear shattering muzzle blast, when there is no time to put ear muffs.
Weshoot, did you try something similar?
Thanks, Onty.
