Well, the cheapest 45 is 58 cents right now...Now, if only 45 came down to 30cpr I'd be a very happy camper, albeit with a big credit card bill.
If you're a Prime member it's cheaper so that would be around 48 to 53 cents a round...
That's getting there...
I would think the ammo makers are pumping out the 9mm, 380 and 556 right now...
Once they think 9mm, 380 and 556 is good they will switch to 45 and other rounds...
