Also, thought about a .58, I just like bigger bores even in modern rifles, but figured the 54 would be a good size. I hear/read the swamped barrels have better balance. I need to avoid something that's front heavy as I injured my left bicep (right handed) and can't hold a front heavy firearm on target for too long before I get some wobble, so that's another reason I though I might be better off with a shorter barrel
