“I use a Windham Weaponry AR chambered for 7.62x39. Also has an ATN Thor thermal scope.”
I think 12ga slugs is best when you a wandering around for a hog but your choice is good for ambushing it. Although I think 30-30 or 7,62-54 are more suitable.
I made the choice of calibre because I already had 3,000 rounds on hand. I also have a 12 gauge semiauto loaded with buckshot but that is too cumbersome to carry along with the rifle, so I have a Remington R1 1911 45 auto.
