So i'm helping a friend of mine reload 308's for his m1a, heres the problem: I trimmed the cases to 2.005, seated the bullet at the cannelure, measured the col(2.720) and its below the min col(2.800). -150gr fmjbt w/c hornady bullet -rem once fired cases -36gr varget -hornady 7th ed reloading manual Would it be safe to shoot? Somebody told me it should be safe because we're loading at 36gr. which is a low charge. What gets me is why is the col short? Defective bullet?
