I know the topic been discussed, BUT: I'm looking for some experienced reloading advice on powder selection for .223's; here's my specifics: 1. Reloading a large volume of ammo; say upwards 10,000 rounds 2. Using 55-62 gr projectiles, barrels are 1-8/9 in. twists 3. will develop an appropriate load before this operation commences with whatever components we select Going to do this progressively on both Hornady and Dillion presses. Looking for that powder that meters extremely well, clean with excellent volume accuracy potential. I've loaded varget, 4895, 4064, RL-15......they are not it for volume manufacturing using this equipment; would prefer a ball powder or similar: does CFE223 or H335 do this? Or, do you have another suggestion?
