Re: A new members questions
I have used both .451 and .454 balls with no problem. They both will shave off a ring of lead when loaded which means they are larger than the cylinder and are sealing. I have used 777 in mine and load 24 gr.(by volume). You use less 777 than you would black powder or pyrodex ( it is about 15% more potent). The 777 is somewhat less "dirty" but same day cleaning is still a good practice. I usually use 27 gr. of Pyrodex.
I also use a lubed wad over the powder which also prevents chain fires.
