[QUOTE="AZShooter, post: 1343785, member: 5219"] No one has mentioned you can use a seating die for the intermediary necking down step. Going from 7mm to 257 should be easy with the use of that die. I never did have good results trying to neck down with a series of bushings in a bushing die. Now if Redding would taper one side of those bushings that would make a big difference. I have considered grinding one side myself but haven't done it yet. If you owned the reamer you could make an intermediary form die. I made one for my 6mm-284 using the 6mm-284 finish reamer and an old 264 win mag barrel. After reaming, the neck area was sanded and polished to make it a bit larger. Works great when necking down 284 win brass to 6mm. Die blanks can be purchased from Pacific tool and gauge if needed. [/QUOTE]
