Iam building a 358 Norma and want to form my brass from 338 win mag or 300 win mag brass. (i know on the 300 i will be pushing the shoulder back and having to do some triming, and with the 338 mag the neck will be a little short)I was wondering if anyone uses any thing other than a FL sizing die for this? or if you have some experience or tips doing this i would like to hear from you.
John
