I loaded up some .308 last night. This is only my 2nd batch of .308, but I've been loading .270, .22-250, and .223 for years.
I noticed that after seating the bullet, the neck on the cases seemed to bulge slightly like the bullet was too wide for the case. It was very slight, but when I ran my finger nail across it, I could feel a slight rise.
I haven't tried to chamber a round yet. The last batch I did worked fine, and I got a .37 ctc group out of the last 3 shots, but I did load this batch slightly longer. The prior group had an overall length of 2.82, while this has a overall length of 2.85. Could this have anything to do with it?
I'm using Winchester brass, 175 gr SMK, 41 gr Varget, Lee Dies, and a Rock Chucker.
Any thoughts?
