Here in NY, they finally lowered the age to hunt to 14 (no rifle in Chautauqua Co.) My son has a Mossberg 500 with a scope but I just found out that there is no rifled choke available for that gun.

I know this may seem like a stupid question, but can my son shoot rifled slugs out of it? What would happen? The choke kit that came with the gun has a mod,imp and full choke. Or am I stuck with getting another barrell? We hunt in mostly hardwoods so we're not shooting over say 50 yds...

As always, thanks for your help and advice
