Looking to build an AR 10 for hogs.
Wondering what the general consensus is between these two rounds.
7-08 all day, everyday. *** This is assuming that you are hunting at night, out in the open, and not in a blind over bait.
8.6 has some cool aspects to it. However, one of the things you'll find hunting out in the open at night is that true range estimation is a bitch, especially when the pigs start running and the LRF capabilities of your equipment are useless due to time. These big and heavy cartridges all have one thing in common - a lot of drop. Whereas a standard .308-based cartridge with a medium-weight bullet is going to be significantly flatter in trajectory. Not only will you get an extra ~50-75 yards of range estimation buffer with the 7-08, but your lead times will be significantly less, and faster cartridges are MUCH easier to hit running animals with.
^ Especially if you're comparing 7-08 supersonic to 8.6 subsonic. And don't believe the myth that the other animals stay put when you shoot one with a suppressed subsonic. Make a pig scream - they all run. If they've ever been subjected to gunfire (regardless of how quiet your rifle is) - they all run. I've had multiple times on video where I've killed one with a 3-chamber brake before and only had the others start to walk off or mill around before like nothing happened.
Add in the cost of components, and the fact that a cheap 120 - 140gr hunting bullet is more than adequate in the 7-08, and it wins by a large margin in practicality. I killed hogs more effectively with a .30 cent, 150gr Hornady Interlock, or .40 cent SST out of a .308, than I did with a 6.5 Grendel or 6.8 SPC and all fancy bullets (>.80 cents per) combined. It wasn't a wide margin, but it was still better and cost me $.40 less per round when I was spraying and praying.
*****
Obviously, if you are in a blind hunting only one pig at exactly ___ yards over a feeder, then the external ballistic advantages of the 7-08 are moot.
And never count out the fact that if you want to kill a hog with ____ chambering in ___ rifle, that you should build it that way and enjoy it. I'm not against any rifle, or how a dude wants to spend his money. I'm merely stating the often-overlooked advantages of the classic and less 'currently cool' options... simply because of marketing and occasionally because of misinformation.
