I have not gotten around to using this powder as I'm loaded with 777. However, have talked to a number of In-liners that swear by it and rave about it's performance. They claim that even with the higher price, they would not go back to any other substitute. But you know, that's kind of the way it goes and another generation of "Propellant" is in the horizon as another fades into the sunset. ..
Be Safe !!!
