Lots of ruffed grouse (& others) have fallen to the 12. If I ever find a decent 2-inch gun before I'm to infirm to use it......
True enough, but, I mostly run into guys with 20 gauge guns grouse hunting. For years. A few nutcases with 16s, too. Hell, I'm one of 'em.
Best,

The last data I looked at from LODGH, about half those who responded to the annual survey used 20's--which hadn't changed much going back 30 years or so. The really big change over that time frame: a real surge in popularity for the 28ga. Slight uptick for the 16ga. Both those gains were at the expense of the 12's popularity. That being said, I have a Jeffery with 28" barrels and pretty open chokes, tips the scale at just under 6#. No reason it wouldn't make a grouse gun . . . although I've always favored smaller bores for grouse & woodcock. But there are plenty of 20's and 16's, and even some 28's, that are heavier than that particular 12.
