This is good stuff! I've shot it in two revolvers (so far), a 2" M642 and a 2" M37. It ignited reliably and shot well in both. I used it in an IDPA BUG match with the M642 and managed to take high revolver. I haven't tried it in my bigger revolvers yet but I'm sure it'll be just as good.
This was my first Miwall purchase but won't be my last!
