Problem with sub sonic’s is ft-lbs of energy and range. Some of the guys are using subsonic 300 Blackouts with 208 grain rounds but they’re pretty anemic past 100 yards. So far the most effective way I’ve hunted hogs is from Helicopters but the terrain needs to be fairly open. Large volume traps work but they’re usually only good for one set and may take a couple of weeks to get the hog’s coming in constantly. Once you trip it they won’t come back. Ar’s work great but a shotgun is the preferred weapon if you really want to take off a lot of hogs.
And like everything else the bullet will still make noise when it strikes. I figured the range wasn’t that great but not having any experience with .300 I just assumed it was better than that.
Yes, we tried the corral method a few times but only got 2 or 3 little ones each time. It needed to be much bigger but those panels sure ain’t cheap!
