Today at the range ( covid 19 safe zone ) working on a load in a Rem 700 .300 Win. Mag. with 200 grain ELDX's, found that 66 grains of H 4350, CCI 250, .013 off lands gave me a .260 c/c group, 3 shots at 100 yds. This after 7 other test loads with same components, FL Resized. Hope someone finds this useful.
