I think 9mm has always been borderline for saving money, particularly if you don't already load your own ammo. If you order 10,000rds of 9mm you should do better than 44c apiece though. Rebel Gun Works I think discount 15% for just 1000rd orders, but they can't ship currently.
Just now it's virtually impossible without primers or powders, but reloading let's you make your ammo suit your purpose.
Primers are even cheaper by the 5000, and 5000 don't last long shooting IPSC. If you can find them, grab them, you can always swap them for ammo.
To actually save money you need to cast your own bullets, preferably from your own recovered bullets, but I don't think ranges let people recover bullets these days. Shooting the same lead over and over again does make for cheap shooting. I think it's only a matter of time until they try stopping us from recovering our own brass due to the primer residue contamination.
Lead (pure sheet, bird shot, bullet alloy) generally runs around $11/kg currently, although you may find it cheaper if you look around. A kilo of lead makes about 100 147gn bullets, or 130 115gn - under 10c per bullet. Again though, order bulk and you'll get cheaper prices on bullets as well.
Powders are your immediate problem though. ADI is normally about $140/kg, or $450/4kg, but trying to find any pistol/shotgun powders is difficult. Unfortunately, if you can find other manufacturer's powders, they are quite expensive.
When I was shooting IPSC, a club member loaded ammo for maybe 20% of the club members, for just enough profit to make his own shooting free. Oddly, the club even then didn't recover lead for their own use, but I think they had a bulk supply deal with Westcastings.
As for time factor, just as nobody pays for your time shooting, nobody pays for your time making your ammo. For some of us, we can make our ammo quicker than going to a shop to buy it.
