I may re-evaluate my maximum loading practices.

My guess is smokeless powder was used in this cylinder.
Ruger says, or said that any load of sporting black powder that will fit in the cylinder is safe in the Old Army, that's about 37 grains if you shoot a round ball, around 30 grains with a conical.
Most of the paper punchers claim 20 grains+filler is the sweet load for maximum accuracy.
