190gr sub-x
Its quiet and accurate. It ahoots perfectly in a 1 and 8 twist where more most 220gr subs fail. Perfect ammo for suppressed ar pistols or sbr's.

Great for hogs and other predators
Mile High had the ammunition in stock, and the first responder discount savings were much appreciated. We use quite a bit of this ammunition for depredation and varmint hunting.
