I am using a 6 power Leopold scope with Leopold mounts. It made round holes going thru the cardboard. What happened is I sighted in at 100 yards then moved a target out 200 yards and could not hit the target and could not tell where I was hitting, so I put a large piece of cardboard out at 200 yards and held my crosshair at the top of the cardboard and hit about 30"below the top. I fired about 4 rounds using the same loads and it pretty much scattered in about an 18" area but all at least 30" from the top. I quit after the 4 rounds and plan to go out again this weekend.
