Hi all, Just got a bp pistol for my birthday and have a couple of questions. It is an 1851Navy Civilian replica by Pietta, 44 cal. Can a guy shoot conicalsout if this suchas the Buffalo Bullet Slick Silver's?Or are you stuck with round balls only?If you can, do you need to use a wad with them? Also,the book recommends some kind of lube on top of the ball for an additional seal. What if anything do you guys recommend?
