I feel that reloading gets you something not available anywhere else. A round custom made to your gun. The only way you save money is when you sell off your reloading equipment and recapture your investment. Or I suppose if you bought only one powder one type of bullet and reloaded range brass using bottom end or used equipment or perhaps a Lee Loader. (sorry I'm thinking rifle here and you are asking about pistol ammo)
The first part of this is the best reason to reload. Custom cartridges for your firearms, that when combined, make for an accurate reliable system that can consistently be depended upon.
As for the rest of it, not so relevant but depending on how you go about it, only partially true.
You are very specific about the cartridges and the amount of said cartridges you intend to load.
If that is a specified amount for a project or all you will ever need, then go to one of the banner sponsors and take advantage of their bulk deals. The amount of ammo you list would have shipping included in the price. This would save you the effort of setting up a reloading bench, picking up the components in bulk, etc.
If you are actually doing a group buy and making up the cartridges for buds at a slight mark up to cover your own costs, the amounts your describe are hardly worth the trouble. IMHO, the bulk pistol ammo prices being offered, negate any reason to consider reloading at all. Often, such as one of the 9mm deals offered by a few of the banner sponsors, it was cheaper to buy their loaded ammo and have it delivered to your doorstep than it was to purchase the components to load them up, even if you were using cheap range brass to do it. The only way it would be cheaper is if you can get the range brass for free. This is often possible, depending on who you work for or follow onto the range. A few months ago, I got onto the range after a certain law enforcement agency had just left. They were cleaning up after themselves and dumping the used cases into the garbage bin. I asked them to just leave the cases and promised them that I would clean them up. They were only to happy to leave the troublesome chore to someone else.
Good deal for me, a few thousand cases of Winchester 223rem, 9mm, 12ga hulls and 7.62x51. Not a few thousand of each of course. About 1500 9mm cases and the rest a mixed bunch of at least a couple hundred of each, except the 12 ga of which there were only 50.
This doesn't happen often though, not for me anyway. If any of you gentlemen that were there at the range that day, thank you very much. It was a favor that worked both ways.
Anyway, I notice that you don't mention any rifle cartridges. If you are just going to reload pistol cases, it will take a lot longer to recoup your costs, say 5000 rounds of each of the cases you mentioned and only then if you purchase your components in bulk.
