We have been invaded by Hogs, my partner and I have killed 60 in the last year. After Hurricane Rita dropped 70% of the oak trees in our county it is virtually imposable to get into the woods. We are having to set up feeders on pipe lines and high lines. I have a feeder set up at 50 yards,500 yards, and 1000. Last Saturday seven bores walked out at 500 yards. Having taken 500lb hogs before we know what a big one looks like. These ranged from 300 to well over 500 pounds. I was starting to regret the 308 was sitting in the rest on the top of my two story shooting trailer rather than my 300 win mag. The 308 will hold 2 1/2 to 3" from the top of the trailer so I decided to go with it. I waited for them to settle down. Big boy had to make it clear that none of the others were going to feed on his side of the table. He finally turned sideways and I sent the 175 gr MK.. He dropped on impact, but got up and made it to the swamp 50 yards away. After a long wait we went to investigate. I saw a 8" scratch on the ground. It did not appear to be the work of a hog. I found the Mk 3/4" under the ground. We had to enter the swamp on our stomachs. Just a few yards in I found a piece of upper leg bone with a perfect hole in it. If the pictures come out you will see the base of the MK sitting in the hole. Due to ten to twelve yard visibility on our stomachs in the swamp. We decided to return the next day with shotguns. Sorry to say we did not find him in this wall of timber. Hate this was so long, but what are the odds of finding you're bullet on a 512 yard shot, and then the leg bone?. Hope I post the pictures correctly.
