at the range this is what i found out.
knight master hunter
burris sig 3-10x40 ballistic plex
100gr 777 mags
250gr shockwaves super glide

my scope says to zero at 125 and the ballistic plex comps for the bullet drop of a 250gr at 2100fps. well my 200yd crosshair was hitting way high like 6". i used my 150yd crosshair at 200yds and i hit about 2.25" low.
i also found that not just wet/dry patch between shots but i had to use a brush/wet/dry between shots to get a consistent grouping.
