This morning I came up with the best long range load for my 300 WSM so far. Magpro powder has been giving me good results in other rifles so I tried it with the 300 WSM. 73 grains Magpro with the 208 grain Hornady Amax seated just touching the rifling gave 2886 fps with 8 fps spread. The group was 1.238" at 400 yards. I used a CCI 250 primer. The rifle is a Tikka T3 Light with the barrel floated and the factory trigger adjusted. With the extremely high BC of the Amax this is a super long range load for the 300 WSM. I have six Tikka T3 Lights and all three will hold under .4 MOA.
