Sarah would never use a bow like that. She's a hunter, guys -- and no hunter (male or female) is going to go into the woods with a fluorescent pink bow.
It's a nice sentiment, and very appropriate in that it's a native-owned corporation and proceeds are donated to support Down Syndrome. But that color's flat wrong. She's not exactly the Barbie type when she takes off the lipstick.
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...
