Every once in a while I get hooked up from range guys at the local base, but I mostly buy my ammo from the gun shop that gives free range time and free rental uses to military and law enforcement. There are cheaper places to buy ammo in town, but they deserve my business.
Good onyou for that
It is easy to repay them in that small way. They match prices on guns and give discounts to us service members too. I try to buy all my stuff there. It is run and owned by a bunch of former LEO and military guys too.
