[QUOTE="aldeerhunter, post: 1342450, member: 99345"] Ok. Because much of the necked down Nosler 7mm stw ammo loaded by Ferguson split the necks upon firing, and a few cases split before being firing, I want to try necking down in steps, and annealing. I have .265 and .266 bushings for my 6br. My thought is to get a 7mm stw bushing die and use the .266 bushing as the first step, and to order the appropriate .257 bushing for the last step. I have not measured the neck diameter of a loaded round or fired round. I think I will measure off of the fired round, and go with a bushing .002 smaller. [/QUOTE]
