Is anyone having any luck using the Shockey stuff or the APP or any of the other new powders? It seems like all ya see on this board are people having probs. It sure is making the ol RS Pyro look pretty appealing. I had thought about trying the APP but after reading some of the posts on here I may just stick to the T7 and Pyro. Thankfully no crud rings...yet...but I do use RWS caps with it.
