I like an open choked 12 ga. with a short barrel. My 26" barreled A5 Light with IC choke is perfect for grousing in the thick stuff.
That said, my last spruce grouse was beheaded at 5 yards with a 50 cal muzzleloader and 370 grain maxiballs... some guys say you can use a lighter bullet, but I like the punch of the maxi's...
