Frankly, having 50 rounds of flight controlled wad (FCW) buckshot is probably enough. That is about $50 from a place like this: https://www.bonefroggunclub.com/col...-8-pellet-with-flitecontrol-wad-2-3-4-le13300. AmmoJon carries it as well. I have slugs as well but mostly for the ranges that don’t allow buckshot (increasingly, all of them). But the Fed FCW stuff is like magic if you look at the tests and professional reviews. I also like the number 1 buck FCW load, but bought pre-panic.
