N568 vs 565 vs 570

I’ve had good luck with 565 and 570

565 was designed by Vihtavuori specifically for 300 grain bullets (in 338 Lapua), but of course it is still adaptable. 570 is likely to produce the fastest velocities for amount of powder used, but has that "dirty" reputation and I try to minimize barrel fouling. 568 has the opposite reputation, very clean burning. It uses more powder, but I also like that it is superior in resilience to humidity and temperature changes (according to Vihtavuori), so on balance have gone with 568, especially since my only real-world application is hunting.

What are you shooting with the N568?
