I agree with this, hindsight is 20-20, but I had always planned on using factory loads so it should not have been an issue. I suppose if I was reloading I would have paid more attention to it. I certainly will if I ever do another.
Rob's experience on reboring is sad, but would not put me off from having a gun rebored. If I got a new gun, new barrel, or had a barrel rebored; the first thing I do is slug the bore. It's hard to choose a bullet or load if I have no idea of the bore size? Had the new bore been slugged before any ammo was fired in the gun, the issue of a small bore would have come to light immediately, and sent back to JES to be rectified. I'm not excusing JES for not doing it right the first time! A customer shouldn't have to return a barrel to be redone. But any shooter should know what he's working with before sending the first round down range.
