223 and 5.56 ?
I am loading a 55 gr fmjbt with 24.5 gr of H335 in LC 5.56 cases and in Remington 223 cases and see no difference in accuracy. Both go under 1" at 100 yds. I expected to see some difference since the LC cases are supposed to be thicker brass having a lower capacity.
Why am I not seeing any difference ?
