I'm looking for some ammo for my new 18.5" 870P that is on its way to my FFL dealer, I'm looking for 00 buck and slugs to pattern and test, I already have Federal LE127 RS (slugs) and LE133 00 (00 buck) are these good choices? what are some other really popular and recommended shells? is there a gold dot 124+p equivalent in 12 gauge in terms of popularity? thanks
