I have been shooting shotguns for 50 years, O/U, Autos.
I recently purchased a Benelli Super Nova for goose hunting.
I went to the range to pattern the gun.
At 30 yards with IC and MOD choaks, 3" and 3.5" Mags, sight picture was back bead under front bead and target sitting on front bead. (6 o'clock hold)
The pattern is a little low with 2/3 of the pattern below the target. I did it free hand as well as bench rest. No difference. I don't see how the shims will help. My sight picture will still be the same. I took it to the trap range and it shoots very nice with lead and I covered the target as I normally do when shooting trap. I read that Benelli's tended to shoot high so you can watch the bird.
Why would the gun be shooting low for me? Thanks
