Thanks for the info. On the cracked neck issues-- I'm sure its metallurgy issues and RUM is not the best brass. I may have to look at getting a batch of 100 good pieces of RUM brass and then annealing it on every firing. Food for thought anyway. Though there will be no way to save the primer pockets. Unless the pockets are an issue of soft brass in the head area which is extremely possible. The case is so big, they may have the metalurgy engineered to where if you tried to push way up into 70kpsi or more pressure ranges the pockets expand. A bunch of us are totally in agreement thats what Federal is doing with their 223 brass. It may be a company CYA issue.
