All loads were produced with WC 300 HAM’R cases, reduce the above charge weights by 5% if using cases made from .223/5.56 brass.
WARNING: Due to barrel bore dimension variations and powder lot differences WILSON COMBAT strongly recommends the use of a chronograph to work up loads in excess of the starting loads. Do not exceed the highest velocity listed for any load and do not substitute any other component for those listed.
Velocities were recorded using a Wilson Combat 18” barrel with Labradar in 90-100 degree temperature. Reduce or add 12FPS per inch for shorter or longer barrels.
NOTE: The 300 HAM’R is designed to use 110-150gr bullets at supersonic velocity and is NOT suitable for heavy bullet sub-sonic use.
