<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: TT</div><div class="ubbcode-body">Hey Bigwheels - I went up to the ACME spot and set up my 11"x17" LV steel target so it was 930 yards away shooting from the "750" yard location (just south of the T-intersection).
Once on target I enjoyed consistent hits but noticed a few rounds high and a little right. The right was probably due to the wind picking up as the temperature started to rise.
However, the vertical was perplexing. If I'm not mistaken I thought you posted something awhile ago about anomalous vertical movement of rounds under similar conditions.
Did you ever resolve the issue?

In a word. No. I have seen updrafts there that can account for SOME of the vertical anomalies, but certainly not all. Especially where you set your target up. The updraft factor is consistent with a 1/2-1/4 value wind blowing the bullet up. You should have seen all the puffy cotton stuff blowing up the hill from there, & take the aprox. angle up from vertical, & equate that into a wind elevation value, & you should be on. However it has to be blowing pretty good to get a 208 A Max to drift up by even a click. So more than likely it was a load, or shooter issue. I also see a lot of people without a bubble level on their rifle have significant cant when shooting there. So you may have been hitting with a cant on the rifle you didn't know about, & once in a while you straightened the rifle out, & they went high. Canting to the right will cause low-right hits, so with dope for a cant in the scope, & you straighten the rifle up from there will cause a high hit to the left, and vice-versa.
Hope this helps.
