Alan, I can identify with the hog work you spoke of. That form of excitement comes for me usually in an irrigated cornfield, where visibility is easier measured in feet than yards. Short is good there, and I assume the tunnel you mentioned might be the pathway the hogs push through briar patches and such, which forces you to your knees. If it's briars like we have here, they are about as bad on you as a mad hog.
Anyway, the recoil is inconsequential in a situation like that. I have a close friend who worked part time for years as a cameraman for a hunting television show. He was once in Alaska, filming along the salmon streams. An old resident guy he met asked him where was his gun. Tripp replied he didn't have one with him. The mans said "Son, this is bear country". Tripp replied that he would be careful. Old guy pulled out his alloy framed, lightweight .44 magnum and handed it to Tripp. Tripp hefted it and said "I'll bet this thing kicks like crazy". Old man replied, without a smile, "you won't even notice it when your hand is in a grizzly's mouth".
You won't either, Alan.
