I use #4 or #5. I find anything smaller and you end up with more pellets in the meat.
I agree, I also stopped using a shotgun on them period. Usually ruffies are just sitting there anyhow so its not like your blasting them out of the sky, so I just use a rimfire on them to the head or neck area. Way less meat damage and I would like to see a guy head shot a grouse with his 12g at 30 to 40 yards without a few stray pellets.
