Do you know the source of your ammo and can you contact your supplier regarding the nature of the primers? Second choice is to shoot them and do the necessary cleaning as if they are corrosive. Too big a chance to do otherwise, in my humble opinion.
You are absolute correct in your guess. They may be part of a case that I got from Century International a few years ago, or they may be part of the fifty I got from my local gunshop last year, I am really not sure. I was hoping that someone would recognize the headstamp and might have a list of corrosive ammo, I just forgot to mention the headstamp in my first post.
I have a list of corrosive ammo for surplus 30.06 that I got from the CMP forum a few years ago, but have personally never seen one for .308. I started to load them today, but decided to hold off to see if someone might know the answer.
EDIT: I just found out that the headstamp (RG) is from the Royal Ordnance Factory Radway Green, UK. But I still dont know about the corrosive part of it.
