When I first got my White I used Pyrodex P like everyone suggested. And don't get me wrong it worked really good. Then one day, I took out 2f Triple Seven and tired that in that fast twist. I never went back to the Pyrodex. 65 grains of T-7 is really accurate. Now you make me want to get out the .451 again.
By the way, I like that stock. It stands out!
