FWIW- H1000, 4831sc, Staball HD never hit 2900fps without pressure from my 22” with 180’s. 320 rounds down the tube.

68.0 grains early on gave me right around 2940 and I just checked my notes, and I got right at 2960 with the same load at around 80 rounds. I'm now at 140 rounds but have not put it over my chrono to see how much velocity I have picked up. I hit pressure signs at 70.5 and accuracy was going south, so I took it back down to the 68.0 grain load that shot really well and that's where I think I'll stay. Obviously work up as every rifle is different.
I get 2900fps =/- out of my 22" Proof barrel running a 175gr ABLR with 69.3gr N565 out of fired Peterson brass & a Rem 9 1/2 primer. BTO of 2.6650". More importantly, it's an accurate load. I loaded up to 71.3, but saw no accuracy improvement.

Those are pretty good numbers, what were your groups like? Also did you run into any clickers?
No clickers, I don't know about group sizing, I was shooting steel at 500 yards, 18"x18" plate. Using 2x fired Peterson brass.

That’s good to know, I started running into issues on my 6.5 PRC after my 5th reload on Peterson and Lapua brass.
Have a gunsmith touch it up with an AW2 reamer. All of the PRC cases have the potential to develop clickers, especially if you stand on it with your load. That's the unfortunate dilemma with cute tolerances that end up interfering.
