The Only-For-Tin-Cans-Pistol

[Highpower]

I'll have to dig it out of the safe and get a picture I suppose. Beefy is a good word. The maximum load is basically the same as a Colt Walker. If you can stuff it in there it will work.  

My usual load is to fill all the chambers to the top of the cylinder, and set a wonder wad over each. Seat the wads then seat a ball over each wad. Stacks up perfectly leaving the ball sitting right at the front edge of the chambers.

This is from the Ruger owners manual.

POWDER CHARGE

It is safe to use as much Black Powder as the chamber will hold, leaving room for the bullet. This maximum loading is usually not the most accurate loading, however.

You have certainly got your cleaning regimen down pat, I'll give you that.
