Most of the load data I see doesn't fit my rifles, my AR builds are 18'' 1&8 223Wylde chambered rifles, I want to use TAC with 55gn FMJ's because I have lots of both! I'm trying to get the most out of the powder safely! I tried 24.5gns and IMO it is a bit slow, 2880's I don't want to waste components or go overboard with too much powder, anybody got good data for this combo?
