I have a good laod for my Montana with the 200 Interlock now. It is a max load accordng to the Hodgdon website consisting of 47.0 grains of 8208, a WLR primer, and 308 Win R-P Brass.
The load went through the chronograph at an average of 2627 fps with a sandard deviation of 7.23 fps and an extreme spread of 16 fps. This is coming from a factory, 22" Kimber barrel.
This load hovers around MOA in my Montana. Some groups a little less, some a little more.
I think this bullet coupled with the Federals mild velocities will make the best combination to suit my interests, and the Interlock bullets are readily avialable and inexpensive to boot.
Ought to work!

...load development with the 160 ttsx, H4198, H322 and benchmark.
Curious how H322 does. Only tried AA2230 so far. It works fantastic in terms of speed & accuracy, but always like the Hodgdon extreme powders for stability. Don't know what temp stability AA2230 is, but it's a normal ball powder.
