While breaking-in the barrel on my new Rem M7 in 7mm-08 I had a disconcerting problem - after some rounds the bolt would be very difficult to lift to extract the round. There was no pattern to it either. I was shooting three different types of ammo and it happened with each one. After one round the bolt would open normally, and the next round it stuck, then the third round it would open normally again so it was not a matter of buildup in the chamber. I used to own a Rem 700 and never had this problem. Has anyone else experienced this? Is this something that will be mitigated after the gun has more rounds through it? Is there a safety issue? I have read and heard a lot about Remington's quality declining since they were bought by Cerberus. I would hate to abandon Big Green.
