Testing earlier this year, I found a flat spot in performance between .060 and .075 off the lands. Depending on wear, they may just work out. Thanks for the feedback, always good to learn something.
I would clean it well and stop using the bore scope to judge barrel life, let the target do the talking. Setting back a chamber is a option if you have your own reamer and get a good deal from your gunsmith or do it yourself, otherwise a set back can run the same price as new plus no one likes using their sharpe reamer on your old chipped up throat. I figure some smiths will, but who wants to be the next customer using that set back reamer ?
