Hornady 5.56 NATO Load Data
« on: October 29, 2020, 11:42:21 AM »
Anyone try Hornady's published 5.56 NATO Load Data and get to compare with Published .223 REM Load data (presumably 60-62 gr)?  I was under the impression the pressure differences between 5.56 and .223 were due to the different measuring device/locations.
