Monte: PM sent back. Thanks again for the help.
Tinkerfive: Thanks for the post! I can now see the wisdom of your post. I got it done last night. The bolt closes more (but not all the way) on the NO GO gage than I wanted it to, but it still (thankfully) will not close on the NO GO gage. Tonight, I remove the barrel and debur the chamber mouth and put abevel in that area. I will also polish the chamber, as set forth above. (Thanks Roscodoh and Monte 6ab for these ideas).
Thanks to all for the help.
