I bet N560 would make that 3,000 in a 20” with the 134I didn't, it was 50fps slower than rl26 in my short barrel 6prc, so figured it'd not be worth it. N565 did get me to 3160 at psi, but accuracy was at similar speeds at H1000. I run everything suppresed so try to run cleaner powders in the overbore magnums. I have a 22in 300nmi as well, using N565 in that, 2970 w/ 215hyb, that thing has some PUSH with the can.
