I have heard stories about how the FMJ 223 would just fly right through varmints and not do enough damage for a humane kill. I was very surprised to learn just how effective this loading could be. Lately I have been using a thermal scope for night-time hog hunting. I would now pick this 223 ammunition above all others for hogs. In my experience, it has shown 100% reliability firing and feeding. It is accurate in all the AR style rifles I have used it in, at least four:2 AR-15, and 2 M4. It does the same way from my Mini-14. On hogs it leaves an impressive wound channel, in many cases penetrating completely with devastating effect. Same thing on small varmints like armadillos, skunks, and raccoons. Don't expect an intact pelt. I have never seen it pencil hole. I don't know why it is so destructive. Maybe it's the "buzz saw" effect. It some how still has good penetration. Unlike hollow points, it is probably maintaining the full weight of the bullet the whole length of the wound channel. It seems to smash bones and still keep rolling. I think this loading will do the maximum damage that you can do on hogs with a 223. And it is at a bargain price.
