so a seach dosnt turn up any info on here but a google search pulls up a couple of threds. i know that there are other .338 rounds out there that would give the same performance but i am a big WBY fan and i do not have a "big" caliber gun so i was considering one of these as my next project. can anybody tell me how they perform with hand loaded ammo and what seems to work well in them? also any draw backs to them that i havnt heard yet. so far i'm reading that barrel life is short like 600 rounds short.
