As others have said, ammo sales is a tough business. Unless you can sell it for less than the cheapest guy online + shipping, you aren't going to move much product. You will also be competing directly with brick-and-mortar places like Bass Pro and Dick's, who can leverage huge buys to get a few more pennies off the cost of each round.
dicks ammo prices suck, I can beat them any day of the week.
