There is great wildcat, the 338 Edge, that uses a 300RUM necked up to 33 cal, which is a great long range accuracy round when combined with a custom bullet; however, Nosler cases tend to loosen their primer pockets after about five mid-load cycles. My question / idea is this: is there any way to use controlled heat, applied judiciously to the base of the case, to harden the case head? Yes I know about the Remmy cases being harder but the consistency is not there, weight to weight). This is a good teaser/ chalange for the advanced reloaders---. Many thanks, Overbore
