rem33, I have seen poi change in all kinds of ways from different bullets / loads. Faster loads tend to hit lower at 100 unless the difference is +400fps, but dont bet your house on it, bullets have no shame in disobeing my predictions.
. Left or right there is probably no way at all to predict. I suspect it has to do with recoil curve, bbl time of the load and harmonics. There is no real way to predict. It amases me to see in handguns the same bulllet wt of a different type over the same powder and same mv hit at a different poi. It has to be the recoil and bbl time. FWIW David tub recomends 4350 speed powder up threw 7mm mag. I have not heard of stelar accuracy from 4831 powders. I would love to hear from more of you who used / tried 4831 and how the accuracy compared to other powders. I may have to try some in H4831sc, 180gr, 30-06 loads just to see what it does.
