No mention of the 6.8 SPC? I see a lot more Federal, Remington, and Hornady 6.8 SPC ammo available in my area then I ever see 30 RAR, 450 bushmaster, 458 socom, 50 beowulf. Plus, when he wrote this "While they will work, I am not a fan of sub .30-caliber cartridges for hog hunting, so I would start with the .308 Winchester" he lost credibility to me. So a .277 diameter bullet won't do similar damage as a 30 cal? Why do so many people hunt deer, elk, beer, and hogs with the 270 winchester round? What about the thousands of hogs we have all killed with the 6.8 SPC? I think the author hasn't completely educated himself on what is available in the AR15 platform and discounts anything under a 30 caliber round.
I left a comment, but it has to be "approved" by the editing staff before it will be posted.
