I can get 40 Grn. 2 FG of Elephant BP under the ball in my '58's. I have not tried the lube under the ball or...the wad. I do know you can really haul down on the rammer to seat the balls. First time I loaded one I neglected to get the ball far enough down to pass the forcing cone...then wondered why the heck I couldn't
get the cylinder to rotate to the next chamber.....until I looked on the left side of the pistol and saw the problemo.
