Unfired new Norma brass worked fine and after sizing and annealing cases stick with same charge weight and bullet seating depth/jump. They're sticking after second firing in this chamber but work fine in another chamber done with different reamer
I've recently had my second 6.5-284 built and having a problem extracting brass. Norma brass extracted fine when virgin now after annealing and FL sizing (.002" shoulder bump) brass sticks. 52.5 grains H4831sc. Reamer was marked 6.5-284 Lapua and came with.284 win headspace gauge. Can anyone help
