145 grain hammer hunters are 3100 fps out of my 22 inch ackley barrel. Probably could be pushed harder also but load shoots very accurate.

Edit to add- that’s using h4831

24" Shilen 280 AI built by LRI. I'm still working tightening SDs but almost everything has shot around 1/2". I've had a couple groups approaching 1/4"

3125 FPS with 145gr LRX, Nosler brass and H4350.
