I have about 5 lbs. of it left out of the 8 I bought. I bought it for a wildcat I have. The lot I have is slower than H870 but it burns about the same, in other words,dirty! I have better luck using rl25 and retumbo, velocity and group sizes are better and the barrel doesn't foul nearly as badly as with wcc860.
Hope you have better luck with it than I've had, also one last thing, this powder isn't controlled as well as commercial powder so you should always start over when you change lots, they say it can be over 15% difference.
