Well, i would recommend a rifled barrel instead of the smooth, but either way. The smoothbore is good for rifled slugs, but not for the better, longer range sabot slugs.

I shoot an 870 in 20ga with the rifled barrel and copper-solid slugs, and have shot deer as far away as 120yds with dead on accuracy.

The difference with the rifled slugs is they will drop much more past 80yds and arent nearly as accurate, but pack a much healthier punch at short range than sabots.

Get it sighted in and blast yourself a big 'un.
