Going to 100 yards should require a scope with parallax adjustments.\
My 10/22 is currently wearing a Burris 4.5 - 14 x 42.
Sighting is with CCI SV at 100 yards was getting 2" groups for 10 rounds.
Something is scoring the lead either coming out of the magazine or entering the chamber.
Will know better after our 100 m. match tomorrow.
