That's all good news to my ears, nothing wrong with 1-1 1/2" groups . I just got a used barrel here, a .308 with micro groove rifling. I'm thinking I have a rarity, which makes me like it even more. Haven't had a chance to shoot it yet though. Slightly off topic, buuut...Does anybody here know the minimum accuracy standard for a military sniper rifle, like those gussied up Remingtons in 7.62x51? Maybe someone here has messed with them? Just curious how picky they are.
