It doesn't take a cannon to take down hogs. I am patient and will make precision shot or I don't shoot. I have taken 10 pigs with the diminutive 300 AAC Blackout since Sept. And these are subsonic loads at about 1000 fps muzzle velocity.
Here's a 180lb boar from the other day. A little over 100 yards at nite facing me with his down, shot was placed right between the ears. Pffft thud.
