Congrats on drawing a cow tag .
I drew muzzleloader cow tag, for the Umtanum B area ,just south of you . Hunt the Barber springs area and close to Bald Mountain , but not that far south .South West Corner of unit 340 . We will be doing a lot of scouting in September .
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...
