Charlie scared me so much, I pulled all my bolts and looked them over
A couple of things: I used to think that Winchester had rough unfinished parts. The Winchester bolts look like a Ferrari compared to the almost new Inland round bolt. It looks like a Nash Rambler. No wonder they could turn them out so fast. That thing has more scratches, nicks, and rough spots than anything I've seen. The finish is also substandard compared to the Winchesters.
Also, wow does that H110 powder leave a bunch of crud all over the place. The bolt looks like it hasn't been cleaned in years and I've only shot it a few times since a complete takedown for the Data sheet. Anyway the bolts all look good as far as integrity.
Your misfortune has made all of us a bit safer.
