The number of guns I'll take to the range every two weeks varies but the number of loaded mags I take and empty is always the same.
Fifteen , full size, eight rounders equals 120 rounds
Four, officer, seven rounders equals 28rounds
I never reload mags at the range so my total is 148 rounds per trip. Sounds like a lot doesn't it? It sure doesn't feel like it's that many when I'm doing it.
