Loyd,
IMO

If shooting over a dog- your 410 with 1/2oz load of 7 or 7.5s will do the trick. Yes a little light in recoil and load - a good friend and a premier grouse hunter used that same load for woodcock and have killed a few grouse using those little 2.5 inch shells.

However, 3/4oz load in your 28 gauge is tuff to beat. Winchester AAs are light in recoil, along with RSTs.

Something to ponder
