I am hunting South Texas hogs using a suppressed AR in 300 BLK. I've been using factory Hornady 208 sub ammo, and I'm seeing the 208 AMAXs going straight through, without evidence of much expansion. The exits look about the same as the entries, and there's not as much disruption in the engine room as I'd like to see. I assume that AMAXs won't really expand much below a certain speed, and subsonic is much lower than that. Supersonic AMAXs perform very well in game in my experience. It's still killing hogs, but not with as much authority as I'd like. Anyone got a fave subsonic hunting bullet for the little 300? I do handload, so factory ammo is not required. I want to hunt whitetails with this as well, as soon as the season starts, which is why I'd like a bit more thump.
