Ok I have been loading .223 and 5.56 for some time now and have not had this problem but I can't figure out what is going on.
Here is the dilemma... I am reloading 60gr vmax for a CZ527 varmint. I am using all once fired Hornady brass, which has all be resized with my RCBS dies (full length). I set the OAL under the max ( can't recall exact length) and all of the brass is under the max for trim length. So looking at it from my angle....everything is good to go. However I am sooo wrong. I took the first test loads out yesterday and the first 4 rounds loaded and shot great. The 5th round the bolt would not close and lock. I ejected it and tried a different round which closed and shot fine. Well the next 2 rounds did the, "no close" with the bolt. I ejected them and examined the rounds. I noticed that the bullets had marks on them from the rifling.
The thing is all the rounds were very close to exact same as far as OAL when loaded. I am using the RCBS competition die.
So to recap, all brass has been resized, under trim length, and rounds measured roughly the same OAL. Just certain rounds would not allow the bolt to close. I even came home and shortened the OAL on the rounds that wouldn't close and after I did it, the problem was still there.
Any ideas what is going on
On a side note that may help, when I was loading the rounds I noticed that some of them seated rough.
