So apparently 20 gauge shells will not fit into a 12 gauge shotgun. You knew this, I knew this but my hands and eyes forgot this fact when I bought this ammo. :laugh: I am selling 100 rounds of Winchester 20 gauge, 2 3/4 inches 2 1/2 dr. eq 7/8oz 7 1/2 shot. Included is 25 rounds of Remington 20 gauge, 2 3/4 inches 2 1/2 dr. eq 7/8 oz 8 shot. $20 takes both boxes. I have absolutely no use for these (unless I buy a new shotgun), I paid more than what my selling price is, I just need to get rid of them.
