I'm looking into the venture of forming brass for the 6.5rem mag. I've always had a soft spot for the caliber and don't know why it didn't catch on as well as the 6.5x284 since they have very similar case capacities, and i would think would be a little bit more effiecent with the shorter and fatter powder column. so here is my concern, this will be my first venture in this type of forming. i have reloaded for a while now, but have no experience in neck turning/reaming and annealing. Looking into buying a form die to make brass out of 7mm rem mag/ 338 win mag/ 300 win mag. Any and all advice would be great. Thanks all.
