hanco, you mentiond pens, a good bud has perfected killing hogs in a pen. I've seen it done a bunch of different ways, this is the slickest.

He walks up on a pen, stops before the hogs get nervous and start running around, probably 15 yds or so.

He uses a cheap .17 HMR with FMJ ammo. While the hogs are staring at him, he lines up on their heads, draws an imaginary line between their eyes, goes 1" above that line at midpoint. He waits until the target is well within an opening in the wire and fires. The hog drops, eyes poked out on stems, weird looking. Little or no bleeding.

He waits until they settle down, does it again. He can kill a whole pen of hogs without blood, squeeling or chaos.
