I was able to purchase 100 rounds of once fired Winchester Nickle plated brass for my 7mm Rem Mag. When I try to full length size I could not get the bolt to close, the head space is wrong so I put a .016 shim between the shell holder and the the brass and was able to bump the shoulder back enough to close the bolt. Read some place that nickel plated brass will spring back after sizing. Any one have any thoughts on this?
