I finally found a good load for my 300 Win Mag M-700 tactical 1 in 10 twist 26 inch barrel. Talk about a picky rifle.
180 grain Nosler Accubond boat-tail
74.0 grains IMR 4831
CCI -250 primer
Light crimp with a COL of 3.400 inches.
Velocity for 5 shots. 3,123 - 3,120 - 3,125 - 3,123 - 3,128 FPS
Group at 100 yards 0.50 inches.
Right now I am impacting 1.3 inches high at 100 yards. I need to find a ballistics program to figure the drop for this projectile.
I have another load using 168 grain match bullets that shoots a smaller group, but it is not worth much as a hunting projectile.
