My NM bear hunt is in 2 days, so I’ll be out of the office the rest of the week but will try to check emails and pm’s at night.
Going to use the 6.5 PRC I built up with 145gr Sierra Tipped Gamekings.

If 300 Blackout changed the sub-sonic game. .338 ARC is the sequel.
Bigger bullet, more energy.
Visually, the difference is pretty striking: the .338 ARC’s case is noticeably shorter and fatter (built on the 6.5 Grendel case necked up), while the .300 Blackout has more of the classic slim, elongated look. The .338 ARC’s bullet diameter is also clearly wider (.338” vs .308”).

Who’s got the chance to shoot some hogs with one??
