I used to shoot over spaniels for their hunt tests, SK-II and IM were nice as the pattern was was open enough to not grind the birds up for the started dogs yet let me ride them a bit for a nice retrieve with the Master dogs. The same combo worked for shoot to retrieve competitions over my AWS.
Over my pointer on wild birds it's SK-I/IC and IM.
Two of my drillings get used for calling bear/big cats and coyote/bobcats, the tight chokes work well with Buckshot and NP BB's. Brenneke slugs shoot well out of the fulls also.
I do have an older hammer drilling that just might see more time bird hunting this year, it has a little longer barrels and is fairly light. It will give me a better feel for bird hunting with a shotgun with a cheek piece.
