Got any good sources for discontinued ammo ? My 870 20ga. slug gun absolutely loves Federal P207SS slugs.Its a 3 inch 5/8 oz.magnum with muz.vel.of 1450 fps Hydra-Shok Sabot Slug HP. Shoots almost as good as my 06. Federal quit making these after a pissing match with Barnes.At least that's what I have heard. I bought everyone I could get my hands on and I am down to my last 5. Somebody somewhere must have a few sitting on a shelf gathering dust I don't really want to start over with a different slug until I have to.
