back with more elevation adj problems

[Savagebien]

i posted earlier this week about how my loads seemed to be, and were shooting a lot faster than what i had thought. well i went shooting again yesterday, and with new rem brass which has more case capacity than the federal brass i was using, i used some powder to compare. anyways i actually had less elevation adjustment to get on at 500 meters than before. with this adjustment the loads would be shooting at about 3200 fps, which there would b no way of happening. because the load is estimated at 2800 fps with a test rifle with the same length barrel. AND the brass i was using yesterday has more case capacity, primers weren't cratered and the heads looked clean no ejector marks. SO, is my scope just not tracking right? its a bushnell elite 3200 10x40 MD. any thoughts and advice would be great. thanks!

put a sheet of plywood up at 400, shoot a group that hits at the top or bottom and then crank the turrets 10 or 15 minutes , whatever your target will allow and shoot another group. measure the amount the 2 groups are apart and you'll know how much the scope is moving.
