I just went out and shot a half of a box of Hornady Custom, 139gr. BTSP in 7MM Rem. Magnum. Two of the cases had a hole right in the neck area. The holes appeared to be burned, not cracked! I shoot Customs regularly, and this is the first problem I have had.
Just a word of warning to Hornady Custom 7MM users! And has anyone else run in to this problem too?
