I tossed out a low-ball bid on an auction for a 54 new Englander last night and won. It was cheap enough that this could be a loaner, source of spare parts for my grey hawk, or another shooter. I need to shoot it before I do anything, but if it does not turn out to be a round ball shooter, I am thinking about having Bobby Hoyt rebore it to 58 caliber. My question is how we know rebored guns are safe to shoot. At the very least, what is the max safe load? Is the amount of metal removed so small that it doesn't matter?
