[QUOTE="Justice1327, post: 2877034, member: 117337"] Bushings will depend on your case neck wall thickness, but I only step down twice. Using Peterson Long 300WINMAG brass, I step it down to .308, then down to the finished diameter for a .284, with 3thou neck interference. The final dimension is not sized all the way down the neck. I size only what is needed to give me a false shoulder. This, and leaving the bullets just touching the lands and removing my plunger, gives me great fireformed brass. I have great results with n570 and especially H1000 at 76.5gr for my 168 Bergers. Mine is the 7mm Practical v2 on the Manson reamer. [/QUOTE]
