I use a 270. I was joking about the knife.
Boar spears are being used often enough now that I've even been seeing factory made spears at some of the gun shops I visit.
Catch 'em live and sell 'em is the way to go,for me.

I know a young feller that crawled up a gully the other day to get close enough to a bunch to put down a big one with a .22LR.
Couple days later,one of my boys was with an older friend that came up on a big bunch in the road and they used the Ford equipped with what I call a "donkey knocker" bumper to bring home the bacon.
Lots of different ways to skin a cat. :)
