I went out to shoot my M1 today, but I had a problem. The standard HXP M2 wouldn't chamber completely. This is the first time shooting the rifle. I removed the round and brushed out the chamber and put the ruptured case extractor through for good measure. Now the extractor is stuck and the bolt is stuck shut. I couldn't get through to CMP today, so I thought I'd ask here if anyone had ever had an experience like this. The bolt did not rotate when it went forward either time.
