Fast Frank... I think I'd check the game laws before I took off hunting with a 30 round magazine in my gun. Most states require much smaller mags for hunting, even for predator/nuisance hunting... like pigs or coyotes.It's 30 round magazine is going to be pretty desirable for shooting at a pack of running pigs.
In South Carolina, they can confiscate your guns, truck, and anything else that happens to be attached to them (such as 4-wheelers) or in them if they catch you breaking game laws... so check your game laws before you go charging off into the sunset with hi-cap mags. North and South Carolina limit you to 5 rounds.
