I loaded up some rounds today black elk your right there was a little movement inside the case I loaded up loads with 56 gr, 56.5, 57 with col of 3.240 there was 0.004 difference between the batch of rounds is this normal?acceptable? I also made 3 rounds up at 3.220 Does anyone see there being a problem with starting at this length or any of these lengths starting?

While I was putting primers in with the rcbs hand prime it looked like the primers were a little squint but I couldn't tell if they definetly were or not although bullet seat looks to be a little higher on 1 side than the other.

I got the rifle and made sure the rounds chambered first with an empty round with bullet seated, 2 of the rounds wouldn't allow me to close the bolt so I pulled the bullet pushed the primer in again with the hand prime and no matter what I done it wouldn't allow me to close the bold on 2 cases which had me puzzled does anyone know what could be going on? The cases and heads were also getting marked a bit with lines the length of the case....is it normal for brass to make easier once it's been sized and tumbled?
