    155gr AMAX in 308 Win

    I normally load 168gr AMAX's for ranges up to 600yards and 175 SMK's for longer. The 168gr AMAX's with the right load have proven to be tack drivers in my 700.

    I bought some 155gr AMAX's a while back to see how they performed at longer ranges. After struggling with really bad groups at 100 yards, I started to do some due diligence.

    What I found using a Hornaday 308 bullet comparator, I was getting variations at the ogive of as much as .020" The really strange thing is the OAL of the bullets were spot on, base to ballistic tip +/- .001 bullet after bullet.

    At first I thought maybe Hornaday had lost the formula for making AMAX's. After measuring a full box of 155's and being really disappointed, I dug out a box of 178gr AMAX's that I had bought many months after the I had bought the 155's. The 178's measured all within .001 total a the ogive for the whole box of 100.

    When I think back, I remember I was surprised when I opened the box and the bullets were loose, not in a plastic bag. Every box of Hormaday bullets I have ever opened was in a sealed plastic bag. The box had the Hornaday holographic seal on the outside unbroken, so the lack of a plastic bag did not alarm me. Right now, my conclusion is the knock off artists have decoded how to make the Hornaday seal and a Cabela's buyer could not pass a good deal up. I bought these on sale from Cabela's, the 178's I got from Graf and Sons.

    I am going to shoot Hornaday an email and see what they think.

    Has anyone had similar experiences with any Hornaday bullets?

      Have you weighed them the bullets that had that .020" ogive variation? Could they also be different weights also?

        Another strange twist, along with the OAL being spot on, the weight are all within a half grain.

          .5 grain variation sounds like a lot. I've never seen sierra mk's and hornady hpbt with more that .1 or rarely .2 variation.

            It is a lot for AMAX's, at least in my experience. I have seen ES of .3 gr within a single box in the past. Frankly, I quit measuring them when I opened a new box, they were generally so consistent.

            I was surprised the ES was only .5gr though for bullets whose shape is so different. I did go back and measure and the ones with the longer ogive were the heavier ones and the ones with the shorter ogive lighter. Within their length sort (.003" lots) they were all the same weight wise.

            In any case, they were meant to be 155's. I think not being packed in a plastic bag inside the box may have been a tip I shouldn't have overlooked.
