RE: Semi-auto's Allowed in your state?
Just have one correction. In PA special regulation areas do allow the use of semi-auto shotgun with slugs, and buckshot in another area. Other than that, like Rob said, no other semi-auto may be used. As far as minimum caliber goes I'm sure they have a minimum but I'll be darned if I can find it in the big game regs. It simply states manually operated centerfire rifles.
