I'm sure that stuff is nasty. I shot a coyote 4 years ago at 109 yards with a Remington HD BB 3" 12 gauge load. Misjudged the distance or I would not have taken the shot. Broke its front leg, rear leg, and back with the shot. I aimed about a foot or so above its head when I pulled the trigger. I had to walk up and finish it off...but it wasn't going anywhere. I was calling when it ran up and made me.. locked up the brakes and would come any closer so I took a hail marry shot at it. I ranged the shot afterwards. My calling partner that was.fscing the opposite way with a rifle still can't believe I connected on it. sure TSS double 00 would penatrate really well. Ive shot coyotes at 20 yards and had pass throughs with some of the HD BB loads. Very expensive and long discontinued....about 25 years ago. Still have some in BB,BBB, and T. I don't know if I'd want to try buckshot on pigs but if I had to it would be with TSS shot. To expensive imo for a multiple hog hunt when you can cast boolits that cost zero dollars if you get free lead like me.
