When did Hornady change the profile of their 150 grain 8mm?

I have an older lot that spec'd out to an OAL of 3.03 (touching lands) in the Winchester. The new lot, 2.974 tags the lands.

The profiles look different too, with the naked eye.

It only takes about .003 difference in diameter at the contact point to make that much different in length. They may have made a new set of point forming dies.

You might check several bullets. You may find they vary all over the place. It is pretty common to find those variations from lot to lot.

Hornady is INFAMOUS for changing things and not telling anyone.

They have mucked about with every caliber I know of...EVERY new box of Hornady's I buy I check the ogive length...I've found 3
different ogive lengths in ONE box of 120 gr 7mm V-Max and 2 differences in a second box.

I found this out after my favorite XP-100 7-08 wouldn't hit a pie plate at 100 yds after I had loaded up 50 rounds for sage rats.

It happens in ALL bullet makers...so I just weight and ogive sort every bullet in every box, separate them and shoot them as sorted, after a few rounds to see where they are hitting.

Noslers have been the most precise and accurate...usually no more than 2-3 per box/bag...I shoot a lot of Noslers seconds and they are almost a good as the firsts. Sierra's are as good.

Speer used to be sh**, all over the place but shot great for hunting accuracy. The last several boxes of mixed calibers were right along side Nosler and Sierra.

You just need to understand manufacturing has build in variance's, just take that into consideration and work up a solution that works for you.

Thanks for the info guys.
