Load data for 300 win mag

[armydog]

Looking for any load data for the Mk 248 Mod 0 300 Win Mag stuff, just getting started on the build. I'm going with a 1-9 twist barrel. Never loaded for 300 win mag before, I have IMR 4064 and Varget on hand but not opposed to getting into another if it works better. Please constructive comments only.

I have used 208 Amax with H1000,with great results..

You will need a much slower powder to sling the heavies, than what you have listed. Look at either H1000 or Retumbo for the big pills. In the reloading depot there is a thread with lots of good info.

H1000 and RL 22 seem to be the "Go to" powders.

Re22 has been the best powder in my 300wm. I shoot berger 185vld's @ 3030fps average. Using cci250's I get 1/2" vertical dispersion at 500yards.
