Well, i've crossed over to the darkside and have decided to get my first semi-custom rifle together. I've decided to go with the 6.5-06AI that I'm gonna have done up on a 30-06 700BDL that has been collecting dust in my safe for a while. Problem is dies; have any of you say, ordered a 6.5mm mandrel and replaced the mandrel in a 25-06 Lee collet neck sizer? Would it work? That would get me a long way on reloading, I figure I could get several loadings out of a fireformed case before I'd have to worry about having a body die made. Well any thoughts are welcome.
