A lot of the effectiveness of this ammo in terms of killing a hog depends on some other factors like the distance and shot placement. You could kill a hog with this Sierra Prairie Enemy .223 Remington 55 grain Sierra BlitzKing ammunition with proper shot placement and at reasonable distances. However, I would consider using a larger caliber for hogs.
I shoot alot and the only bullet I use are prairie enemy. 223 55 grain. Deer, hogs, coyotes and other small game. Head and neck shots only.
