.45 Colt Cowboy vs Black Powder ?

I posted this on 'Experts' & got little response, probably in wrong forum.

This is a Question concerning hazard, if any, of using .45 Colt Cowboy in a black powder SAA frame, s/n 92K. Cylinder, barrel & innards are 1960s modern Colt parts.

Shooting Cowboy in other guns doesn't seem much different from standard ammo other than dirty cleanup.

I looked up the ballistics on the Cowboy and standard .45 Colt and the Cowboy is 250 grains lead bullet with muZzle velocity of 750 feet per second. The standard .45 Colt is 255 grains & 860 fps.

I doubt that makes much difference in wear & tear gun-wise.

Anyone have info as to pressure differential or pressure characteristic difference?

Any other info or comments appreciated.
