Can the poi change vertically besides velocity change?
I went to the range checking two loads. Both are 140 grain bullets, one is a TSX and the other is a accubond. Both loads are around 3200 fps. I haven't got a chance to re-check the accubond on the chronograph since going up a 1/2 grain on the powder charge but I am pretty confident that the loads are no more than 25 fps difference in velocity.
What I found was that the Accubond was 1 inch lower and 1.5 inches to the right of the TSX. I was a little surprised at the difference of impact but also that the accubond was shooting 1 inch lower at 100 yards.
What do you think?
