Lets think this through.

Whats cal. is this weapon? 50 cal. nothing magical. Large? yes.
but none the less the same diameter as my muzzle loader. there is a tremendous amount of powder pushing that slug though. They are impressive to shoot, no doubt. I think that if you could pack it to the woods and get it set up before your quarry high tailed out of dodge, then it would certainly do the job.
