I guess it can be done, but if you bought a .223 to shoot 1000 yds you bought the wrong gun.
I like Varget. It fills the cases completely and I seem to have the best results with it. Then again I am only shooting my .223 at a measly 450 yds and in.
For recipes:
Buy a manual or use manufacturers specs. Don't trust what people tell you. At the very least do a double check on internet-forum based recipes.
