So I bought my first break barrel. Picked up the Benjamin Trail Combo from PA. Mounted scope, and hit the range. Couldn't get zeroed in at 15 yards. With windage all the way to the left couldn't get closer than 3'1/2" b/t POA & POI. Otherwise grouped well, which seemed odd to me. I didn't have another scope or rifle to swap and compare. Looking for thoughts. Think I wrecked the scope already, or looking at a barrel issue?
