I carried loops for a time, as an armored car jockey. (20 years ago) The looks I got from people ! The manager of a video store asked my partner, "Why does he have all those bullets" ?
His response ? "Hes not the mail man ! He takes your money to the bank".... To make it funnier, no more than any two rounds were the same. At some point I bought two Safariland Comp 2 loaders and a carrier for them....That was the end of my loops. We also carried speed strips in dump pouches in those days.
