I really don't know why you would use a large 50 cal round on a hog or why your would need to shoot 500 yards. The first time I went hog hunting, I shot from about 50 yards and the second time I shot from exactly 150 yards. I hit the second hog square in the vitals with a .270. The exit wound was about 6 inches in diameter. There is no need for a large round. You just need to be accurate because you don't want to loose too much meat or destroy a possible mount. Your not going to see a true wild hog over 150 lbs and if you do, it was a farm raised pig, which is not hunting in my book. Sight your rifle to 200 yards and use a small ballistic tipped bullet and you'll be fine. If you need to take down a large boar, I suggest putting one through the head.
