My experience with the 110 V-Max has been limited to it's use in .308 Win as we once issued it (Hornady 110gr TAP) as duty ammo, kills hogs on contact.
I've not tried any supersonic loads in the .300 BO so I have nothing to offer in that regard. I see guys killing the shit out of hogs though with Barnes 110gr bullets loaded supersonic. I have sone, just have not loaded them up.
I'm 99% sub guy when using the .300 BO and I've used 220gr, 200gr, and 208gr projectiles which certainly are not expanding at all at about 1050 FPS. I have to make sure I'm within 50 yards AND make a good high/forward hit for success. Behind the shoulder with subs is a no-go based on my experience.
