[QUOTE="Pdvdh, post: 1342456, member: 4191"] Annealing is the cure for split case necks / shoulders. Should always anneal case neck/shoulder area when swaging down a parent case neck. Otherwise you'll risk split case necks upon 1st firing, and excessive neck tension on seated bullets. 2-3 thousandths less than the outer case neck diameter with a bullet seated is the correct size neck bushing die.
