My son picked up a lower he had shipped to Advanced Weapon Systems on Airline Hwy, and he said they had a wall covered in powder. Don't know what types.
Thank you all. I have been doing some research and have decided that as of now with the supply of bullseye being so sporadic I have found a new ball powder that I am going to use. If you know of anyone who wants some 700x send them my way. I have 2 lbs with 1 opened and 80 grains missing due to test loads
