I need a hand here Gents, my cases are sticky. The facts: once fired factory loaded brass full lenght resized, mic'ed and cleaned. The problem: the rifle bolt is hard closing and the rub seems to be on the outside edge of the rims. These rounds were fired out of this rifle. Mdl pre-64 win 70 .338 win mag, Win brass plain and Federal plated, RCBS dies. Am I doing something wrong or is there a fix. Thanks in advance.
