Dude fill out your profile and signiature, and in future type a properly structured thread title if you want people to respond.

Vertical dispersion (bad dispersion) is indicative of crappy barrel harmonics and a powder charge that is not in line with what produces the right pressures for your barrel.

The easiest way to remedy this problem is to perform a ladder test out at about 300 yards.
