Went out in the fields yesterday with the new AR to scope out a famer's field he swore was full of 'hogs. Found the field full of cows, so I sat down under a tree for a combat nap. When I opened up about 20 minutes later, the bovines were gone, and there in the middle of the field 100 yards away was a groundhog working its way toward me, down a gentle slope. I assumed a braced sitting position and fired, spinning the critter around. He proceeded to roll over and resume his track towards me. This surprised me as the Nosler 55 Ballistic Tips have been effective in the one shot department up to this point. So, I drew down and squeezed off another round for another hit. Same thing, the pig rolled over and kept coming. Emptied one five shot clip, reached in my field bag for the second clip, saw it had only one round in it (moron), loaded, drew down, recited the Hathcock credo and connected right 'twixt the little varmint's eyes, putting him out of his misery.
I'll spare the gory details, but suffice it to say that six rounds of 55 Ballistic tips don't leave much of a groundhog's internals, well, internal. Checking the critter, I saw he was headed for a warren of holes in the middle of the field big enough to drop a tractor into, and that explained his continued forward momentum. I'm just glad this wasn't a safari and he wasn't a Cape Buff. One thought I can't get out of my head, though, is "Hmm. This is the Army's main battle rifle..."
