I put a Bushnell A17 scope on my father's Marlin 783 .22 magnum and sighted it in today. The scope is amazing, very clear optics. I shot this target at 50 yds using WW HP .22 magnums. About 3/4" at 50 yds which I attribute to the quality of the scope compared to the Bushnell 4x scope that had been on the rifle.
