I'm a new 1911 owner, so I need to start buying some .45ACP. I haven't had to buy my own ammo for a long time, so I was a bit shocked to find the cheapest .45 at $20/box. Ouch. I suppose buying a case at a gun show would cut down on the unit cost, but how much? Between parking and entrance fees, I would have to save a bunch to just break even. Is there any hope, or is it just going to cost me no matter what?
