I have a Vortex Viper 1x4 on a .300 AAC Blackout, it seems that the vertical adjustment is not even close. Has any one else had this issue, if so how can you test this without going through allot of ammo.
when you say not even close, what is that? how much? the way you test it without using any ammo is clamp it down so it can't move and turn the turrets while the hair is on a yardstick or predetermined marks at 100 yards. this will show you how much it moves.
