Just got back from the range. New 111fcns with custom shop barrel. I have a box of factory loads and shot one round, cleaned and de-coppered and shot two more.
Attempting to chamber a fourth round the bolt stopped short of closing and I found it difficult to extract the round.
What I found is the top of the casing caught some internal lip and deformed (approximately 3/16" wide and curled back).
I removed that round and shot two more and ceased to return home to clean again.
Using a mirror and reflecting sunlight I can see nothing unusual in the chamber. I did not "carefully inspect the round" prior to attempting to chamber. I feel I may have slowly closed the bolt rather than "jacking" it in quickly as the rifle was in a sled.
Has anyone had issues with this occuring on their rifle?
Should I be concerned?
