I have a new shockwave and it shoots 12" high at close range with all ammo. Laying a straight edge along the receiver shows the bead to be over 1/4" low making it impossible to see when the gun it pointed on target. I am considering installing a raised bead, one that has a bead base that is 0.45"-0.50" over the barrel. Have y'all experienced a similar issue and how did you fix it ..... Other than aiming at the grizzly's feet.
