John, first, I keep meaning to call you but life is getting in the way. My question was related to potential future plans....2018 at the earliest so there was no rush. Now to this question.
I have two guns with nice, open chokes that I really like for Ruffed grouse and the odd woodcock. One is a F.W. Heym 16 gauge SxS that weights 6 pounds 4 ounces. And the other is a J & W Tolley 12 gauge single barrel that comes in at 5 pounds even. It's my favorite. Obviously with the Tolley I use very light loads. But I'm running against conventional wisdom here. Because both guns have 29" barrels. Most noticeable on the Tolley because of the extreme light weight, the length of the barrels help keep the momentum of the swing going.
The Tolley is my favorite because of the light weight. It's a joy to carry. And in my experience, the second shot on ruffies is just about always a wasted, Hail Mary shot. Better to not take it.
This is just my opinion but I think the concern about longer barrels being unwieldy in the grouse woods is overblown. Not entirely wrong just not as big a problem as it's made out to be.
What is the barrel length on the 28 gauge you are considering? That would be the deciding factor for me.
