I'm thinking about picking up a .54 barrel for my current .50 FL, not as a replacement, but to have something with a bit more punch available when needed. Do any of you swap barrels out very often, and if so, have you noticed any accuracy problems after doing so? I'd like to have a situation where, during hunting season, I can go from one to the other and not have to worry about it taking a few rounds to settle in each time.
