The only caliber ammo I shoot that can't be bought off the shelf is .221fireball, and I'm set with good brass and primers for that.

Will be shooting a .223 quite a bit now and have plenty of lake city brass and powders for it too. Since this isn't a rifle meant for precission shooting, am trying to figure if the cost to buy bullets/brass/primers will be about the same as purchasing off the shelf ammo at $300/1000. It's available again everywhere in these parts.
