I've made a (big?) mistake with a special rifle. 270 custom Win. that shoots .3 MOA as far out as I've tested (370 yards). Some of my reloads were sticking. I have been resizing the necks and bumping the shoulders, but not resizing the cases otherwise. Got the idea to paint one of the cartridges that wouldn't chamber to see where the paint would scratch off to find where the resizing was needed. Somewhat jammed the cartiridge in and it is now totally locked up. Nothing I can do will dislodge it and I am afraid that some random gunsmiths "fix" might hurt the rifle. Any experienced insight as to an approach to fix this will be MUCH appreciated!!!! Thanks in advance.
