I'm purchasing a .458 SOCOM upper to put on top of one of my AR platforms and plan to cast and reload my rounds to keep the cost down. I was looking at the LEE molds but most of them are .457 diameter and I was thinking that I need a .459 diameter to properly work. Is this correct or will the .457 diameter bullets work OK? I've also looked at the RCBS molds but some of their reviews aren't all that good so I was wondering if anyone has a mold, bullet, and recipe that works well in their AR and they would like to share?
Thanks for your help
