made in 2005. The only problem with the full charge is getting a ball seated on top of it. Likely a lot of stress on the rammer. There is no particular indication of excess pressure, recoil etc with the full charges but 55 grains is a decent level for most shooting. My 60 grain charges were mainly to see what would happen with various powder types and I never have shot them extensively.
The only experience I had with ASM was a nicely finished Dragoon. The finish was nice but the other aspects of the revolver were NOT. Chambers were of different sizes, timing was pitiful. It had to be reworked in a major way to make it shootable.
