It's true that for any cartridge where ammo sells in 1,000 round quantities, the savings from reloading are minimal. A lot of the savings from reloading depends on your source for brass and how well you can recover and reuse it. If you are loading for a semi-auto that beats up and loses a lot of brass you lose a lot of the savings right there. You'd have to buy bullets in the big cases such as the Hornady 55 grain FMJ's that are something like 6,000 quantity and get brass used in as large quantities as possible to beat the 1,000 round cases of loaded ammo costs significantly. And if you are shooting such a quantity of ammo as that, it means that you need a progressive loader such as one of the various Dillons that cost as much as a rifle. There goes your savings for several thousand rounds of ammo. Guess what I'm saying is that if saving money only on a semi-auto 223 for all around shooting/practicing/self defense is your only interest in getting started into reloading ammo, you might not want to bother with it. On the other hand, if you think you might try loading for other rifles also then the other advantages of loading your own might be worth it to you later on. One big advantage I like about loading my own is that once I find a load that shoots well in one of my rifles, I have several hundred bullets, enough powder and primers to produce several hundred rounds of identical ammo. That way I'm not subject to not being able to find the load my scope is zeroed for if my ammo runs out the way I would be if i relied on factory ammo.
