I re-suggest my previous post. You are not going to be removing a ton of metal off the end of the pins, so, take a small stone to the field and stone a little off the ends of the fp's and see what effect it has. This is too easy to do not to try. If you are worried about scratching the bolt face, then use a little masking tape over the bolt face and push down where the pins hit, to force them through the tape, and do your rounding, then remove the tape before you fire.
