I know this is more of a reloading question than casting, sorry..
I'm a newb with casting/reloading for shotguns but I would like to start loading an extremely tight patterning buckshot load. The now discontinued #1 Federal Flitecontol had decent patterns out to 50 yards with cylinder bore 18" shotguns.
Is there any comparable handload? I understand the proprietary wad was the largest contributor to accuracy.
