The rifle is a model 11 long range hunter chambered in 300wsm. I managed to find a box of 150 grain sierra bullets and some IMR 4064, according to the loading manual the minimum charge was 53.? so I started at 54 and went up to 61 (max is 62) in one grain increments (54, 55, 56, etc.). COL is 2.8. I loaded 5 rounds per load and headed to the gun club even though it was stinking hot out. I was waiting 3 to 5 minutes between rounds to let the barrel cool and everything was fine until I got to the rounds loaded with 61 gr, I put a round in the chamber and could not close the bolt. Tried a second round and used a little more force, still could not close the bolt and now the bolt is stuck! A few light taps with a rubber mallet when I got home freed the bolt and the round. I measured the col and it was dead on and a few hours later the other 3 rounds chamber fine. I'll try to post a picture of the stuck rounds because they have some marks on the shoulder but its hard to see. So did I over heat the rifle? Do you think this did damage or will not be accurate?
