gs50401,
You really might want to consider an inexpensive setup that allows you to load only that cartridge. I think Lee makes them...
You could get one powder, one type of primer, and one type of bullet and do some plinking. You might find a load that works O.K....
I would think it wouldn't take too many boxes of factory ammor to equal the price of a hand reloader...
Just a thought...
For what it's worth, I have two 223 barrels and they both shoot M.O.A. or less out to 150 yards and many times at 200 yards...
