6) He recommends breaking the shoulder first. If the pig can't run it isn't as dangerous.
Don't ever count on a hog not to run just because it has a broken shoulder. And I would dare say more hunters are hurt by wounded hogs than not. I shot a 100lb sow last year with a 12ga slug. Right thru the shoulder, damn near took her leg off, messed up the off side pretty bad too. She hauled @$$! And when I caught up to her she was waiting on me. She was about to have a go at me when the 2nd slug hit her.
My go to hog gun was always a 20" bbld riot gun. Short bbl makes it quick and easy to handle and I like the 7+1 capacity. I used cheapie Wal Mart 1 oz slugs and they do the trick just fine. But then the shotgun just got too heavy what with no sling and all... So rather than buy a sling for the shotgun I went out and Bought a Puma 92 in .454 Casull. I really like the 9 round capacity now and it's a good powerful round and in a package much lighter then the shotgun. Holy crap! It doesn't have a sling either! Hm...
