These are copper jacketed FMJ bullet. They have a cannelure and a boat tail with a flat base. These were sold to us as first quality bullets but we found that the OAL variances were way past what we would consider first quality. Most are fine, but some of the copper on the base of the bullets didn’t get folded right so it makes the OAL something like 50-70 thou longer. The ogives are still the same so seating depths should be similar even with the longer boat tails. I wouldn’t expect better than 2-4 MOA unless you sort the short from the long ones.
