I'll chime in bc I have a similar setup except I have a SA 20" carbon proof 7 saum. I have a couple loads that I have tuned for my rifle. None are screaming fast……the fast ones were too hard on my very hard to find ADG brass. All hit hard and work to 500+ yards on pretty much anything I hunt including a big bull elk two years ago
143 Hammer Hunter , 58.3 h4350 , fed 215m, ADG brass, COAL 2.870. 3033 fps
168 Berger VLD Hunter, 64.5 H1000, fed 210m, ADG, COAL 2.960, 2820 fps.
180 Hornady ELDM, 58.5 H4831sc, Fed 210m, ADG, COAL 2.925, 2675 fps……before you say that is an anemic load it is super accurate, carries 1500 ft pounds past 500 yards and you don't have to worry about the ELDM blowing up at short range like the guys that hot rod them. I LOVE this combo and it is my go to load. I have loads for an 180 Berger hybrid also. Are they as fast as a LA running a 28" tube? Not even close but they hit hard and brass lasts! Don't get too caught up in the velocity game and you will be very happy.
