Trying to decided between 20-22”. Would love to hear what real life speeds people are getting with heavy for caliber bullets.

Barrel length
Bullet
Velocity
Powder

Thanks!
 
23in 7.5tw, 134 eldm at 3080, bout half grain below psi at 3140. Lapua brass, H1000 210M primers, suppressed.
Trying hard to decide between 20-22” for mine. Going to be surpressed. 3000fps seems like the magic number in my mind.

You'll be able to run it with 22", not with an 18". Rl26 would make all the difference if you have some.

I don’t and probably won’t for a while! Did you try any of the VV powders? My 300nmi loves n570.

I 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.
