Finally got a chance to work up some loads with this bullet in my .300 win mag.

Best loads were with Imr 4831
Shot three 3 shot groups:
.70 .40 .34 were the group sizes at 100 yards.

Next best was H4831:
Groups were right at 1 inch, and slightly over.

These were max groups in my rifle with a 26" barrel.
Velocities were at 3390 with both loads.

Had the same kind of accuracy with 100gr Triple shocks in my 25-06.

These triple shocks are much more accurate than the older style x bullets.

Do not try to seat these bullets close to the lands as pressures will jump.
These loads were appx. .05 off the lands.
