Hornady 62gr website download data shows more powder in 223 for 2230 and xbr than for 556 and equal max loads for TAC. Emailed em and they simply said lab said that where pressure got high.
Would someone explain to this fudd how that works? Did I just get complacent and not notice that 556 doesn't always have more powder than 223 at max? Below are powders listed in common:
556
AR-Comp 17.6 gr.-24.6 gr.
H322 20.0 gr.-23.3 gr.
Accurate 2230 20.5 gr.-23.6 gr.
H335 21.2 gr.-25.4 gr.
IMR 8208 XBR 21.8 gr.-24.4 gr.
