CVA Hawking .50 cal ball, side lock. I've owned this for about 10 years, bought used. Shot only a few times; groups well. This comes with all the things necessary to take it out into the woods - dry powder, almost 100 lead balls, percussion caps (and 207 primers b/c there are adaptors out there that allow you to use these on the side locks; don't have one), bore butter, cloth, tools to measure and load powder, tools to remove a stuck load.
