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, I surely hope my comments didn't step on any toes. I simply wanted to point out that I check all my guns, whether they are cast bullet, jacketed, factory ammo, or reloads, prior to shooting them.
I've had enough guns over the years, and reloaded for so many, that it's just part of my procedure for any new gun or barrel to check bore size. I also have gotten to where I do a Cerrosafe chamber cast, so I can not only check chambers, but also see what the transition to rifling looks like. Often it will keep me from chasing my tail if I check it first, and make sure that it will accept factory ammo and bullet dimensions, or it will tell me what size I need for either cast or jacketed bullets. I have had brand new guns that surprised me with slightly small or larger bores, and I ended up having to pull bullets on factory loads and seat proper sized bullets.
