DJ, I'm not sure how many .50 caliber rifles you have but I'll bet you your Disco that Dan is using a muzzleloader
BTW I don't know him either.
You make some valid points but I would have been going for the head shot myself. I know my gun and my ability, exactly why I didn't shoot the one running by. I've seen heart and lung shots go much farther than a head shot. They tend to fall where the were standing.
When the guys I hunt with are using muzzloaders at the end of season we are looking for one thing, meat in the freezer.
