Still working on pre-panic supplies including primers at $27 per thousand and powder at $22 per pound. I've been casting bullets since 1973 using salvaged lead (wheel weights, type metal, range scrap) so the only hard costs have been electricity for the lead pots and bullet lube. I have at least one lifetime supply of brass, some of which has been loaded 20 times or more with modest charges, no signs of wearing out.
So:
Primers at 2.7 cents per round
Powder at 1.6 cents per round
Bullets (electricity & lube) maybe 0.5 cents per round
Brass (again, and again, and again, so I call it zero)
Total about 4.8 cents per round, $2.40 per 50-round box, $48 per thousand round case.
Just about the same as I figure for most handgun calibers (.38 Special, .357 magnum, 9X19, .44 Special, etc).
Shopping at today's inflated prices for primers and powder (if you can find them), or buying bullets at retail or bulk-delivered prices, I don't even want to think about that.
After the last period of shortages (2008 to 2012 or so) I made a point of stocking up on primers and powders, usually buying more every month as available. I am hoping that some degree of normalcy will return before I run out of stuff I laid in before the current panic.
I still remember loading most handgun calibers in the mid-1970s for 65-80 cents per box of 50, just a little bit more than .22LR ammo at that time. I also remember digging up the pits on the police range to salvage spent bullets and scrounging every tire shop and print shop within driving range for scrap lead, driving a 1967 Ford Fairlane and making payments on my $17,700 house while trying to keep my kids fed on skinny paychecks as a young cop. All my pocket change every day was set aside to pay for the annual deer/elk hunting trip so I wouldn't have to upset the family budget in the hopes of putting a couple hundred pounds of meat in the freezer (which was purchased on low monthly payments, of course).
It is a different world these days.
