You can still find ammo for less than .75/rd in stock most places. And hunting ammo is going for about $1. That may be cheaper than reloading by the time you track down all the components. Gone are the days of $99 spam cans of ammo, but it shouldn’t be too hard to dig up some cheap surplus, if you’re just looking to bust some milk jugs, and you could save the brass if you can find ammo without steel cases.
