2 wheel dolly or a pull wagon with pneumatic tires and tubs tote you ammunition to and from. If someone asks to borrow it get a deposit and then refund it when they bring it back. Cash is king but if I was in the gun and ammunition sales I would take credit cards also just price accordingly because your going to lose 3 to 5%.
I've got a dolly but much prefer a 4 wheel cart. They pull easier and your less likely to have something fall off if you are loaded down. I've been doing gun shows for years, and I don't take credit cards. There are usually ATM machines at most venues which helps a lot.
