I was out at the range shooting my '06 today with some 180gr remington core-lok. They were shooting and grouping great until I had a failure to fire. The firing pin definitively hit the primer (no shallow strike). I tried to fire the round again and nothing. Chambered a new round and it worked fine. The rifle shot great the rest of the day but the FTF has sort of turned me off from the remingtons. What would cause the FTF. On a side note the person I was shooting with also had a FTF with his 270 core-lok.
