Damn, $200 for 500rds of .223 ammo?!?!?!?!
Take that $200 refund, and go buy a Lee Anniversary Reloading kit, buy another reloading manual in addition to what comes with the Lee kit and read up on reloading.
80% of what you need to get started here for $130
Then beg, borrow, or shanghai some small rifle primers, worst case they will cost $4-5 per 100, buy as much as you can afford to. Gunshows are good places to find them when online/local places are out...not the best prices, but they have them.
Pick up a few pounds of H335, its the same powder as used in M193 and M855 ball ammo. Look for it to cost about $20 per pound out the door. 1lb should get you at least 200rds of loaded ammo. It is cheaper to buy it in bulk in 5lb jugs, but that may not be possible with todays buy it now climate of panic buying...
Check out midway for 55gr Dogtown bullets or Hornady 55gr bullets. I recommend 55gr bullets to start with as their is alot of reloading data out there and its a very forgiving bullet weight in .223 reloads. Pick up Lee .223 dies at Midway as well,
in stock for $14.50 at midway for lee .223 dies
Digital calipers cost under $20 at Harbor Freight or even Lowes/Home Depot.
