I'm trying to reduce the cost of my AR plinking, and will shortly start reloading for my 223. I will use Lee's 55gr bator mold, gc'ed. I have found load data on other fourms that show as little as 6.5 gr of Unique, but the Alliant site does not list anything for the 223. If I'm trying to reasonably cut costs, what starting load should I use, or should I pick s different powder? Thanks for any help.
