Been thinking about this and I just suspect that open chokes are the way to go. had my 28ga AyA opened from Mod/Full to Imp cyl/Skeet three. Skeet three was smiths idea, He said it was a bit more open than Mod. Thinking back on the grouse I have got into I suspect skeet/Imp cyl would be the way to go on a forest grouse gun. had an 870 Special Field bored Imp Cyl and it was pure death on grouse! Wasn't worth a darn in open country! have added a 28ga CZ Bobwhite and it has tubes, a first for me! Think, not sure right now, I have a skeet/Imp cyl in it. also have a 410 I use shooting pigeons for my dogs in training and it is full/full. Seems to work alright but one of these days I'd like to try it on grouse. Unfortunately I live in central Ore and not a lot of game birds anywhere near me now! need to make a trip back up to western Montana one of these days for forest grouse.
