An 11 twist is good for bullets up to 200 grs>>>>no more, UNLESS you are at very high altitudes.not to confuse matters, but what is the twist rate on the barrel? I have a Tikka T3 in 300WSM with a 1:11 twist rate, and was informed the 4350 would be too fast burning for the heavier bullets like the 200gr ELD-X. recommendations were the 4831SC or or IMR 4955 (which I purchased but is now discontinued Enduron powder).
Sounds about like what I want . How was the recoil with a 150gr bullet ?Back when H4350 was hard to find a few years ago I went with AA 4350 in my Model 70 300 WSM, under 150 gr NAB's and NBTs. I was able to work up a hunting load that shot 1/2 MOA out to 500 yards with that combo.
Very mild with the load I had, it was actually a pleasure to shoot. The factory all weather Model 70 stock also has about a 3/4" foam butt pad tho, so that helps.Sounds about like what I want . How was the recoil with a 150gr bullet ?
