So, it looks like I am going to start reloading for 50 BMG soon. Loads will be for a bolt rifle (EDM Windrunner). I don't have an established load yet. Will likely be using Hornady bullets, at least to start. I have only seen CCI arsenal primers. Does any other commercial primer manufacturer make primers for it? By the way, I am a fairly experienced reloader, having reloaded for rifle, pistol, and shotgun for many years. Any of you who reload 50 have any advice before I start screwing up expensive components?
