to me nothings been proof tested like a military action especially a hundred year old one shot thousands or tens of thousands by every idiot that wore a hat. if there was a heat treatment problem or a real design problem they would have found it look at some of the crap military ammo out there overloaded underloaded cases too short too long bullets out of size volley firing when your barrel is glowing like a forge then poping of a few grenades. that will test it. i'll stick with the old.stuff walmart can keep their 700 remingtons with their extra trigger locktite. brought that other topic cuz i didn't know this was going i'm glad i asked.
