Weird that they're differing lengths and lead plugging the tip in the one, yet they all weigh about the same. Maybe weight is the primary QA/QC control. Clearly bullet length isn't.
I'd like to know, for at least my own knowledge/use/correction, the source of failures to expand on game. I don't have much tolerance for full metal jacket performance from a hunting bullet. It happens a minority of the time but I want the majority of the time performance to the extent possible. So lead to the very tips of the bullets, differing bullet lengths that could result in solid closed tips due to the jacket being pinched together in the bullet swagging dies, different jacket thickness at the tip, or anywhere else on the bullet... For example, where did the rest of the jacket material end up on the short-stacked bullet? Or did that jacket not begin life in the manufacturing cycle with a sufficient mass/volume of material? Overall bullet length is an important quality control check, since it could identify a bullet with greater potential to fail - when impacting large game. So that was the crux of the comments/questions in my earlier post.
