Just a heads up that Ableammo has 16 ga. Bismuth in stock. It's made by a company owned by Rio Ammo. I ordered a box of 25 for $47 plus shipping. Maybe should have ordered Niceshot, but I'll give this a try. Kent TM just impossible to find. BP had it for $57 for box of ten shells. Hope it works. I have a box of steel, but I'm a little reluctant to use it in my older gun.
