Knocked out 600 rounds of a 9mm load for my comp'd 509t. 124 grain RMR bullet over some VV 3n38. Runs 1215 FPS out of a 4.6" barrel with no pressure signs and makes the gun shoot so damn flat. I'm 100% sold on VV powder. I used to run it back in Kansas when I shot USPSA for it's cleanliness and remember why. I ran 200 rounds of this on some steel last weekend at the gun club and my X300 Alpha's lenses didn't look like I fired a single round.
