Specifications for H&H Paradox ammunition call for 15:1 alloy.

Wouldn't you like to give this gun a go with real black powder? I think you will be quite pleased if you construct a "factory equivalent" black powder load.

My 10b H&H Paradox really sings with its intended load of 8 drams. Mine's a 10b, mind you, so don't go pouring 8 drams in a 12b! I would have to go to the books for the original H&H 12b load.

That's a very nice gun. You have done well!
