since you have a rifled barrel... you might also want to consider the Hornady SST slugs. i shoot these out of my 870 epress and can leave all three shots within a 1 and a half inch group at 50 yards with open sights.
I agree,the Hornady SST is a fantastic slug for shotgun hunters. I shoot them out of a Mossberg 835 UltiMag and they live up to the claim of 200 yard accuracy. I've zeroed my scoped gun at 150 yards. The slug hits 6 inches low at 200. Placed the crosshairs on the top of my '06 buck standing broadside at exactly 200 yards and dropped him in his tracks. Great slug!
