"I can't say for certain out of the Knight but in the Omega, definately three Pyro pellets would give you an additional 200-250 fps over 125 grains of T7"
With what weight bullet? It certainly won't happen with a 348gr Powerbelt. I can't see it being that much difference with a 250gr Shockwave either. EITHER WAY, I WILL report the exact velocity of each(250gr Shockwave with 3 Pyrodex pellets, 3 777 pellets, 120gr 777) Sunday or Wednesday, weather permitting. And that you can bank on in Denver. Disc Extreme and Omega hopefully.
"150 grains Triple 7 pellets is allowed in your Omega, Encores, Knight Extremes, Elites, etc."
Add the Apex and Wolverine 209 to the list.
Also, the Austin Halleck 320/420 is rated for use with 150gr black powder/ black powder substitute by volume even showing a picture of loose 777!
