I have an unknown lot of Hornady 60 gr VMAX (I threw away the box because I loaded all 100). After reading a post where someone mentioned measuring their finished ammo, I found that the OAL varies between EXACTLY 3 sizes: 2.267 (what I had the die set for), 2.271, and 2.263. The die seats the bullet from the ogive and not the polymer tip (I am pretty sure) and the pressure concern would be the distance from the lands..........so.......am I okay here? It appears that Hornady mixed three lots of bullets or there are 3 different machines at Hornady.
I have a box of 150 grain SP's in 270 that are obviously from different lots because the cannelure is at different places. That is more of a cosmetic issue.
What do you guys think?
