Advice sought on using Australian ADI powder AP- 100 (equivalent to SR 4756}in 45 colt with 255 grain bullet for use in Winchester 94 Trapper.
Suggested load is 11 grains.
Looking at slightly slower burning (longer barrel) and increased powder volume for reliability of ignition.

I use 24 gr H110 or W296 with 250 gr in the Winchester, and get 1525 fps. It kicks.

Also have 18.5 gr of Alliant 2400 as recommendation.
How does that sound?
