I've decided to add .223 to my list of calibers I'm reloading for. I have 3 ARs of various setups that I could feed with it, and once my supply of factory ammo is shot I'm going to start rolling my own.
My question for the group is, what powders and bullet combinations have been most successful for you all. I have two ARs with 16" barrels and 1:8 twist rate and one with a 20" barrel and 1:7 twist rate, if that helps. I know you can get cast to work in ARs, but I'm not really interested in going through the process of getting it to work, so I'd appreciate jacketed bullet recommendations if you have any.
