I actually have three favorite hunting guns. For upland birds in the field it would be a 12 ga. parker DH choked open IC / Mod. Moving into the thicker stuff for grouse and woodcock it would be a cut barrel fox sterlingworth choked Cyl/Cyl. For squirrels, if I can't get them with the first shot they are free to go, I use a single barrel Forehand and Wadsworth hammer gun choked Full.

I have been Parker-less for quite some time. My DeHaan .410 and Harry Greener's Emperor share equal time chasing Ruffed Grouse.
