You do NOT reload what can be bought however. Are you reloading 147gr FMJ? No Campro or Berry's copper or wax spray painted lead. Real FMJ. Something like American Eagle 147gr. 1000 fps, 300 foot-pounds. Can be had for $300 per thousand. $0.30 each, free shipping.
Being a savvy reloader you can get decent primers from Tenda for $0.035 each. Order a couple of years supply and get free shipping. To reach that power level and velocity needs about 5gr of whatever powder you like that works. Best price probably Hummason at around $240 + $20 for shipping for 8 lbs. Titegroup need not apply. Won't meet the power or velocity of the factory stuff. So, about $0.025 a round for powder. Now you need bullets. I have lost track of where to get decent prices on REAL FMJ bullets. Even 10 years ago I think they were pretty expensive, around $100 for 500 if I recall correctly, so at that time around $0.20 each. Add in brass. No you don't get to go to the range and pick it up, not at any of the ranges I have been to for quite some time now. Most of the crap lying about on the floor is steel or aluminum these days anyway. If there is real brass lying about, it usually 'belongs' to the range as well these days. I can guarantee you that anything I leave lying around (which I NEVER do because that isn't the shooting I do any longer) is so shot out it would belong in a smelter. Factor in another $100 for 1000 so-called 1F after they are cleaned and culled and amortize across the lifetime of shooting and reloading. Probably $0.01 a shot. With THESE prices, it is sitting at $0.035+0.025+0.20+0.01=$0.27 a round for 147gr FMJ so $270 per thousand. So, yes, you save around $0.03 a round.
But wait! Now add in $1500 for a good progressive press like a Dillon 650 with dies, shell feeder, bullet feeder, powder alarm, primer sorter and feeder, and all the other bells and whistles so that you actually CAN reload 300 plus rounds an hour IF it runs properly without screwing up, so that you can reload your 10K plus rounds a year. Hmm, $0.03 a round savings. Wow! Break even on the press is 1500 / 0.03 = 50000. Yes, that is correct, 50K rounds to break even reloading 9mm 147gr ammo on a new Dillon 650 kitted out press actually CAPABLE of doing so. How do I know? I owned one, for years. It cranked out about 15K .357 and the same amount of .38SP, and about 4K 0.40 S&W before my back decided for em to give up on handgun. Changing out calibers was a PITA in my opinion with near total disassembly and reassembly/fine tuning required.
Now, yes, you can run low power 115 or 124 gr plated or waxed lead Berry or Campro bullets, with Dominion primers, 2.8gr or less of Titegroup or similar powder, with really questionable range floor brass to reach the reload costs that you are speaking of, but they won't meet match shoot power levels, and have significant feed problems in a lot of pistols. So, even if you want to reload these plinker rounds for $0.17, at $0.13 savings, it will be just a bit over 11500 rounds to break even. I would suggest that very few people shoot that much in a year unless they are significant match competitors and if so, they certainly are NOT shooting plinker rounds either in practice nor in competition, nor are they sitting behind a press incapable of supplying them with decent amounts of decent ammo in a reasonable period of time. They are too busy shooting.
