Hot loads. I wouldn't sweat it yet. Give the gun some shooting time. The FGGM 185 Berger Juggernauts that I've shot so far - THAT is some hot ammo! But it's effective, as hell. It's not "too hot", but it's up there. They're not joking around with those loads, I'll tell you that. @Armed Eye Doc will like that part.
Those 185 Juggernauts are serious. I need to replicate that load... I'm full-Hornady Whore on the 178 ELD-X projectiles right now, changed ALL my .308Win handloads over to them, and they are absolutely badass, in the handload that I have going on. Unreal projectile, for a .308 Win loading... I need to pick up some of these 185 Juggernauts, and start loading them. For them, Ive only fired the factory Federal ammo with them - but they're impressive, as all hell.
