BPI X-stream spreader
Probably tighter than optimal for grouse in close cover, although probably about right for plains grouse, especially with a flushing dog. The X-stream spreader might be worth a try. It is sized for use in a shot cup for 12 gauge, or without a cup in 16 or 20 gauge. Use in 12 gauge without a cup would probably work ok though. It displaces 1/8 ounce of shot. If stack height proved too high, roll crimping would gain some room if you aren't already doing that. I use it with 7/8 ounce of #8 shot in the .028 right barrel of my 12 gauge LC Smith.
