There is an awesome article in The NRA's American Hunter magazine this month written by Bryce Towsley. It is a great story about his beagle Barney and their hunts while he grew up. Pretty darn neat story!
I get the American Rifleman magazine instead of the American Hunter issue, but I'll see if I can grab a copy of the American Hunter latest issue from a friend. My brother in law has a beagle pup he'd like to train. I think he'd be interested in seeing it.
What does "gauge" mean anyway? As used here gauge means the number of round lead balls the same diameter as the inside of the barrel (aka the bore) that it would take to weigh one pound. It takes 12 lead balls the same diameter as a 12 gauge barrel to weigh a pound. The smaller 20 gauge would require 20 balls of that barrel diameter. The larger bore 12 gauge would require 12 lead balls of the bore diameter to weigh one pound.
In general the number of pellets in a shotgun shell...
