Kind of apples and oranges, but I reloaded my last batch of 9mm for less than 10 cents per round using Barrys Mfg plated hollow points.
OK, a quick bit of research for low dollar but reliable parts........
Berrys .40 155 grain plated flat points $108.00/1000 = 10.8 cents per round
Winchester 231 powder, $120.00/8 pounds, @ 6 grains estimate per round = 9333 rounds total, works out to 1.2 cents per round
Primers about 3 or 4 cents per round (if you can find them)
total is you have your own empty brass is about 15 cents or 16 cents per round for good plinking ammo. About $7.50 or $8.00 a box of 50.
