I bought a 3" chamber .410 Winchester model 37 a while back, and have found the ammo quite expensive. It is primarily a new shooter training piece, a collector's item, and for rodent/ squirrel control. The birdshot is expensive enough, but buckshot shells are over a buck a pop! (maybe that's why they call it BUCKshot ) I like to keep some around for "just in case." My question: I have seen these "handgun" .410 shells, I'm guessing for the Taurus Judge type guns, and they are priced quite competitively. Can I shoot these through my crackbarrell? They come in #4 and OOO 4 pellet, and are a 2 1/2" shell. What say the Glocktalk brain trust?
