I am loading some 45 colt with Goex 3f. I measured by volume 40grain of it then I weighed it for giggles and seems to be between 38 and 42 gr by wieght. Apparently the slight shaking during the pour into the volume measure settled some of them. They all seated to the crimp groove without any noticable case bulging. Can you create an overpressure situation with actual blackpowder and no airspace? the powder came to within .100 of top of case and bullet measured .280 to the crimp groove so I have .180 compression. 40 gr is the highest I've heard of the Colt being loaded with BP, and at 14,000psi.
If it fits is it good to go?? Or can you overload with Black powder???
Gun is a recent manufacture so I have a little wiggle room over an old iron SAA, in strength at least.
