[QUOTE="Stonewall2, post: 453178, member: 6935"] I am using .300 Win brass to make 7 mm Rem Mag cases. First run thru a .338 Win f.l. die to set the shoulder and then f.l. size with a 7mm Rem die. Anneal necks before neck turning because the hardness -spring back of the necks now is slightly different. The case now head spaces on the shoulder exactly before firing . The necks will clean up at twelve and three quater thousand thickness in all the lots of Winchester .300 Win brass that I've used so far.. Glenn [/QUOTE]
