I bought no questions asked from a dealer in South Dakota. Never asked me for an FID card, which I don't have. Never understood the need for an FID card to buy non explosive lead balls? Why don't you need an FID card to buy ball bearings? Anyway that is for another day. I would have posted but did not want to take any buisness away from Mike for belly weights. Since he said what he does here is the site I delt with
http://www.precisionreloading.com/. Go to On line catalog, reloading components, shot, Hornady Magnum Lead Buckshot. They come in 5 lb bags, which is a lot of shot. The smaller the shot the more you get, sold by weight, so the #4 is probably enough for a life time. Good luck. Paul
