Ive stated before that shooting .45acp in my .45 colt mountain gun I lose a lot of speed due to the chambers.
.45 colt moon clips are fragile and .45 colt brass is very inconsistent.
Now I think with the .45 win mag brass it will fit acp moon clips and the colts cylinder better.
Does anyone have any experience loading for it? I won't be shooting factory ammo and just looking for 270gr@950fps
