There seems to be quite a discrepancy as to the max load of H335 with 55 grain bullets. They list max load at 23.2 H335 for 55 gr bullets, my lyman lists a higher max load. I have been loading 24.9 of H335 with no problems and no signs of excess pressure. Which book appears to be right ?
Also the new Hornady lists 5.56 but has very few bullets listed.
It also says the 223 is a shorter chamber than the 5.56 so do we use the case COL in the 223 lists or in the 5.56 lists since most AR15 barrels are chambered 5.56 ?
