Problems on the range..

[kacerrob]

i have both a full case sizing die and a head sizing die - both redding premium dies. Prior to running them through I trimmed all to the 2.525 per my Nosler reloading book not thinking I would have to push the shoulder back. I will pull the bullets and powder and run it though again after adjusting.

Start at about 4:00 in... It shows you how to properly setup your sizing die with cam-over.



Here's a good informative video from our forum buddy Jeff Brozovich (his handle is "Broz") that deals with your current situation, about resizing brass that is headspaced too long causing bolt pressure when closing the bolt.
