YES!
I am not a big boomer guy but scheduled a trip on the King Ranch for Nilgai. I built me a 22" 30 Nosler and my buddy who was going with me wanted a 22" 300prc. After doing powder research and hearing all the speed claims, I figured it'd be a perfect candidate for the shorter barrels.
I loaded up two ladder tests, shot them both and my charges didn't go high enough to hit pressure. I came home with plans to clean the rifles and's load up some more. When I cleaned the rifle I ended up noticing how dirty it was and switched to H1000.
I use RL15 in my 7-08's and thought there was no comparison. N570 is without any doubt the dirtiest powder I've ever used.
Having said that, I have plans to use it in a 6.5prc soon haha.
