[QUOTE="bhtkevin, post: 684680, member: 45546"] OK so my buddy has a custom MG Arms 300 Win Mag and we are practicing for an upcoming Ibex hunt but his rifle is doing something weird. 100 yards: +1.5 inches... 3 shot sub-1" group No adjustment to the scope, move to 200 yards... 200 yards: +2.0 inches... 3 shot sub-1" group Huh? According to every ballistics table it should be +1.5" at 100 yards and around zero at 200 yards. Any ideas what could cause this? I am going to shoot the gun next time and see if I have the same results and we are also going to back up to 300-400 yds. Side note... We are shooting off of a lead sled in the prone position for now until we are comfortable everything is sighted in and working as expected. Thanks much, Kevin [/QUOTE]
