ORIGINAL: Sharp Shooter

You guys know that I have a 54cal Renegade that my grandpa gave me and it is shooting good. I want to be a PRB shooter and it is doing that. I have had problems with this barrel like pitting (I think), and I think it could be bulged. When I was shooting conicals and when cleaningthere are two tighter spots closer to the muzzle and it gets real loose in a few big spots near the bottom. I am thinking about just getting a new Green Mountain roundball Barrel for it. I just dont like my barrel but it doese shoot ok. I would get a 54cal or 58cal. I did ballistics and the trajectory is not far apart between the two, the energy is not too far apart either. I know where to get stuff for a 58cal so that is not a big problem. I am almost thinking the 54cal since it will do the job, roundballs are cheaper, and it is easier to get stuff for. (but the 58cal is somewhat easy to). What do you think? I will use it for the Rocky mountains here in Colorado. (Elk, deer, some day moose). They will both do just fine on these animals. I know that if I start casting, Lee makes a mold for the 54cal to.
