I weigh each bullet because I've found a few discrepancies, not many. Other than that, for the past 10 years that I've shot them they have performed flawlessly. Longest kill on deer, 605yds, Every shot on whitetail resulted either in the deer dropping in its tracks or it going maybe 25 yds. I shoot them in .243, .270, 30-06, all perform equally well. Even the cannelure ones except that the cannelure is not where I seat my bullets so the rounds look awkward, but even those perform well. I shoot partitions and accubond long range.
