So my $0.02
I don't know what you spent, but jacketed frangible rounds are a niche item and are likely pricey during normal times. When things calm down, I doubt you would be able to unload them without taking a nice loss. Right now your ability to move them is better, but projectiles are the one thing not in super short supply. Right now I can't get what I WANT, but I can get something that'll work. Which is basically the same thing you are offering.
I can go and order 62gr bullets for $121 per k right now and the only wait is for it to actually be packed and shipped. Their inventory says they have over 1.1 million in stock, and they have had them up for a week plus.
To turn it into loaded ammo, right now you would need a press (scarce), .223 dies (super scarce), various reloading tools and accessories (mostly available), small rifle primers (ultra scarce), .223 brass (limited, but available at a premium), brass prep equipment (because the brass you can find is likely not even cleaned, much less sized, trimmed, swaged, etc.), powder (limited, but if you aren't picky just requires some stalking to pick up), etc.
During normal times, getting set up to reload rifle is minimally a $300-400 proposition. figure right now that is probably doubled. So you will be having to play the track it down game or pay scalper prices for each one of those, or you can just do that with a case of ammo and probably be in about the same place but have a few hundred more rounds.
Right now, even with a lot of luck and patience, I couldn't reload 9mm for less than about $0.40 per round. Possibly not even that "cheap" because that was my best pricing a week ago.
.223 is likely around $0.45-55 per round. IF you can get all the parts. Right now for that price I can get brass and bullets right now, and would have to stalk 8lbers opf powder. More realistically you will find powder in 1lb increments limited to two with full hazmat charge. which would put you at the higher end of that price range if not over.
If you want usable ammo ASAP, you should just keep a look out for ammo and be prepared to pay $1 a round or more.
