If you play around sxs shotguns long enough, you will eventually wind up with 2.5” and 2” chambered 12 ga guns. With the current ammo shortage, it’s hard to keep feeding 2-3/4” guns, much less short chambered guns. But I’ve noticed that 28 ga, is readily available. I suppose few here shoot 28s. I’ve been buying 28ga Win AAs and Federals at walmart for about $11 a box. So I thought it might be worth it to get 12/28ga chamber inserts for short guns and shoot 28s in them. So far, I’ve found Briley and a couple others make inserts, but they are made to fit 2-3/4” chambers. Would anyone know of a source for inserts for 2” and 2.5” guns?
