To the smoothbore experts: I have searched and haven't found anything that exactly answers my question. First off, I have to use a shotgun for hunting on base, and a rifled barrel isn't in the budget at the moment, and after researching if I am limited to buckshot, then that's fine: I would like the ability to use rifled slugs through my Weatherby SA-08. I have read that the IC choke would work fine, but I wouldn't want to go any tighter than that. My questions is, do I need to be concerning with the direction of the rifling on the slug that would potentially cause the choke tube to significantly loosen or unthread completely, or am I stressing over nothing? Any help or insight is greatly appreciated.
