I'm pulling the barrel out of the shell to do some 'massaging' of the feed ramp/barrel edges and then polish her up. Will report back on results.
ETA - Barrel had been pulled out and deburred/polished. I wanted to open up the feed ramp/barrel and do a little blending but that would change the feed angle so decided against doing it. Pix of before and after:
Before deburring - Markings where the copper jacket of the JHP slammed against the barrel edge could be seen on both sides of the feed stack:

After deburring/polishing - Wish I could fill in the gaps between barrel and feed ramp! Wonder if JB Weld would survive in this hostile environment???

Hand cycling is now successful in feeding Hornady Critical Defense albeit still have some visible bullet tip damages:

Need some live fire testing but not today...it is snowing like a sumbitch right now
