new Rem. 870 supermag turkey gun/ IC 665/ Nitro 3" 1 7/8 oz. #4x5x7

[truedouble]

Just picked up my gun and according to the Nitro chart it said that the IC 665 should pattern the best.

I'm shooting it tomorrow.  Any advice and/ or what should I expect to see?  Am I good with this part. shell?  And thoughts on POA vs. POI out of the box with the rifle sights.

Thanks
