In ‘14, I went west of my house about 2-2 1/2 hours, asked the owner of a sporting clays course, if I could have some empties? Yep, you can, but ya gotta take em all! Sure,I said. Boy, o boy, did I get a load! At the time, I had a ‘97 Dodge 3/4 ton long bed. Full to the top of the bed! Holy mackerel! Took a full day of sorting. Now will never scrounge hulls ever again.
That was an awesome catch!
Good luck
