We developed Tin Star specifically for Cowboy Action Shooting, knowing that you take this sport seriously. It is a single base nitrocellulose gun powder with certain properties that are similar to Black Powder, but with none of the unfavorable characteristics associated with that propellant. Tin Star gun powder is reliable, burns cleanly and has the bulk density you want for reloading the old original Black Powder cartridges. With Tin Star, you’ll have the ammunition you need to succeed in this demanding sport. The rest is up to you.
