I have sold my "modern" 20 Ga guns and have only 2 1/2 inch Elsies left. I also have buckets full of 2 3/4 Winchester AA hulls that I would be willing to cut down to 2 1/2. Does anyone have recipes for 2 1/2 AA hulls? I know some will say lengthen the chambers and be done with it but to me half of the fun with these guns is shooting the ammo for which they were designed.
