So i just changed barrels on my savage model 11 to a 308, i set the head space with a go gauge and i put a piece of masking tape on it for a no go gauge. I have shot about 30 rounds of factory ammo through it and it grouped ok about 2 inch group at 100 yards. I just picked up some 150 gr accubonds to hand load, so i was trying to get my over all cartridge length and my book says that the 308 max is 2.810 the problem i have is i set my die above that at like 2.95 and colored the bullet so i could see when it hits the rifling, i expected the bolt to not even close on it but it did and i never seen any rifling, so im wondering if i need to tighten up the head space or what? thanks
