Small bit of advice, based on a few years of loading .223 (in case you are just getting started in reloading).
1. you can buy good plinking/shooting bullets cheaper if you buy them in bigger lots. Keep an eye out and you can sometimes pick up Hornady 55 grain FMJ for less than $10 a 100. Sometimes you'll find Hornady 55 grain soft points for the same price. Most folks will tell you that the soft points are more accurate than the FMJBT.
2. You can buy primers cheaper if you get them by the case. I bought 5,000 small rifle primers today (Winchester) for what it would cost me to buy 4,000 if I had bought them in 1,000 unit boxes instead of five 1,000 unit boxes strapped up in a larger cardboard box.
3. A ball powder is so much quicker, easier and more consistent to drop out of your powder measure. I've used BLC2, H335 and TAC (have top revisit TAC - what functioned/worked in my carbine with mid-length gas system short stroked in the 20" with a rifle length gas system).
Lots of places on the internet to buy brass and bullets. Buying powder or primers on the internet and having them shipped to you will cost you shipping and a hazmat fee in addition to the cost of the powder or primers. That's one reason I go to a local gun show to buy powder and primers. I sometimes find the powder I want at local gun stores, but no that Bass Pro is changing Cabela's into a Bass Pro clone I'm no longer seeing S&B primers on sale at Cabela's and it appears they aren't stocking them at my local Cabela's. Bass Pro's price for primers is just ridiculous compared to the gun shows.
You can make some good shooting .223 ammo once you find what shoots good groups and still functions in your rifle.
