MOD or IC for my smoothbore with Rackmaster?

Hey guys,

Would you use a mod or IC with a smoothbore (I shoot Benelli Nova)? I am going to be feeding it Winchester Rackmasters.

I am leaning toward IC. Haven't had a chance to pattern it. Used Challengers in the past with IC and figure that should work.

Thanks

ether should work try one with a three shot group from 30 yards and see were that leaves you .good luck Dutch

Im using my benelli nova with IC using rackmaster slugs.

Like mentioned, go to the range and fire some off with each choke and see what u get better groupings with
