[QUOTE="Mike Matteson, post: 2133015, member: 101791"] Kind of on the same thing, but I am building a 6mm-280AI wildcat rifle. Getting 280AI brass from Peterson, when they are available and in a 500 lot, so I won't run out brass for my life time. I am having a reduced the neck dia. 1. I can cut the necks to thickness at the 280AI caliber first then size them down to 6mm. OR 2. I can size down to the 6mm and then cut the necks for thickness. What I see is sizing down the spring back as a possible problem. So I would think that using a mandrel that would get ID to. .243 after spring back would be first, and then cut the neck for thickness. That's the way I am leaning towards. This the first time I am using a tighten chamber in rifle. All the others rifles I had built have been standard chambers dimensions. [/QUOTE]
