Growing up its always been either 12 gauge or 20 gauge. I have never really given much thought to other calibers until I found my old Ithaca m37 in 16 gauge. Today I was looking around my local Wally world and found some 28 gauge shells. The old timer next to me picked up a few boxes, looked at me and said "best dang caliber for birds that there is". I just nodded and walked off as I don't have any experience with the caliber. I wish now I would have talked more to the guy cause now I'm wondering. What would the more experience shotgunners on TFL think?
