I just started to reload shotgun shells and have used some of my pistol powders to get started. It became quickly apparent that powder is consumed a lot faster than my pistol loads. Instead of the smaller 1 lb. containers I plan to buy something more in bulk. Clays seems to be a very popular powder but I haven't seen any of it. So, what is the current 12 ga. powder of choice that you can actually get your hands on? This is strictly for trap shooting.
