Thread: Aiming and sight rails

Hey guys. Part way through last duck season i bought my own shotgun and started to use steel at the same time.

I was using my uncles stoeger semi and lead and did fairly well with the ducks, didn't have much trouble making them hit the deck. Since i got my new shotgun, i really struggle to get anything really and miss easy basic shots that were straight forward with the old setup.
I bought a Winchester SXP waterfowl gun and looking at it it seems to have a large sight rail at the trigger end which raises the tip of the barrel. Is this normal, i haven't checked the stoeger as it's at my uncles house but i think i'm shooting high. I also did some clay targets today, got smoked by the young lad but he used a escort semi and i also found it easier to hit the target with that than the winchester.

How should i be aiming with this thing?
