21”s ain’t a bad trade off...esp if you are planning on shooting suppressed.
139 Scenars at 2980 out of an 18” Bart suppressed doesn’t suck!
That's where I'd like to be... Sorry for the hijack but josh remind me are you running SAUM or PRC?
Have and shoot both Marty....
Above reference is what I’m shooting out of the PRC.
147s were a NO GO in both FYI. The PRC has a Bart 2B 5R and was blowing up the 147s about 30-40 yards out of the muzzle. The SAUM was re barreled with a fresh HawkIll last year. When I went to true DOPE up out to 1500 my drops were WAY out of line with any ballistics engine. The ATACR was box tested, velocities were confirmed on LabRadar and MS. Long story short, the jackets weren’t holding up and I was getting a SEVERE degradation in BC. It’s not an isolated lot issue and somehow Hornady “can’t seem to replicate” what guys are seeing in the field.
That same lot of bullets has been GTG at 6.5 Creedmoor/6.5x47L velocities.
