H110 in an AR15? Bullet weights?

[TheAlmightyBob]

I would like to add my experience. I use H110 with bullet weights up to 150gr supersonics. But from starting at 147gr and up I use AA 1680 for subsonic loads. I also found temp problems with H110, but since I dont head out to play till its 60 degree's and up, I dont have a problem with it. I also found out that above 150gr, the 1680 give me more consistant velocities and much lower deviation numbers.
