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 2 wheel dolly and some tubs, thanks for the suggestion. I can't really justify taking credit cards and the setup for that, this is a one-time event for me.
