I have a "custom" .73 oz. loading for 3" 410s that involves using Cheddite hulls, H110, roll crimps, and nickel plated shot. It is the hammer of Thor on small game birds like doves and quail. I took a limit of doves with it on opening day about three weeks ago, with my 30" barreled Dickinson S X S.
Been real busy with farming, Tom, but I'm trying to get you some loaded before you come to GA for your late quail hunt this winter. I need to see if I can get another 100 new, primed hulls.
Edit to add: Just did another online search and every supplier I can find is out of stock on the new, primed 3" Cheddite .410 hulls. Bummer .........
