I had some AA#9 around so loaded some up with 300 XTP's. I was impressed with the lack of muzzle blast and very good accuracy. It was a little dirty burning, but the good performance was impressive. So, how come you dont hear more about this powder when loading the 44 Mag is discussed. Any one else using it? Does it suffer the same performance swings as H110/WIN296 being it is also a ball powder? Gonna load up some more and take the chronograph next time.
