I just had a look at my Nosler bullets I have been using and they seem to have these tooling marks on them as well, I switched to A-max becase of two things uniformity of the tip and the fact they dont have these marks on them... the Noslers even though they claim to be high quality match have alot of imperfections... the tips all are not the same... they have these tooling marks which other manufactures dont like Hornady Sierra and Berger...
I have ran some of my Noslers thur a tip uniformer... I have yet to shoot them to see if it makes any difference at all... I am guessing because I made the tip bigger they will have more drag and drop.
Regardless the Nosler Custom Competition bullet line for me has not shot worse then 1 MOA during testing out of a basic remington 700 nothing special... even with these un-uniform tips and tooling marks they are still a great bullet and pretty good value.
Mirror finish .308 168 A-Max its about a perfect is a bullet can get physically... I didn't weigh them or anything.
.308 168 Nosler Custom Competition notice the tip isn't exactly perfect. This Nosler doesn't have those tooling marks for some reason... maybe they changed out the tip forming die...
On the right you can see the one I ran thru the tip uniformer.
.308 Nosler 168 with tooling marks, uniformed tip
Here they all are waiting to be tested... tiped one on the left, normal in the middle and A-Max to the right
