Nope, but I've been thru 100's of rounds of their stuff in .45, 9mm, and .380 with no problems (my PPK/s doesn't like it,but it's a very finicky eater) - clean shooting, accurate, and reliable. The bronze stuff washes off with soap. Aside from the tick and hair loss, I seem to be fine (JOKING!). It's good stuff for the price. M2
