best load for a ruger m77 mark II 300wm???

[brianbenham]

I have bow hunted most of my life and I am want to start trying some long range rifle hunting I'll be going to Southern Utah this year on a Mule Deer hunt and want to know what the best load is for a ruger m77 mark II 300wm. the scope I have with the gun is a Leupold 3-9x40mm vari-x II. I have talked with Leupold and im going to have them install windage and elevation turrets on my scope. but before they can custom design the turrets they need to know what the specs on my cartridge are. So I want to start trying different loads to see what I like. Can someone give me some info on what load works best for you? The rifling twist for the standard model on ruger's website Say's it is 1:10. If you need more info let me know thanks.

i have hunted in utah. i like a more powerful scope. i have several 300 win mags. when we go to utah we load : 165 balistic tip ; lapua brass; wlrm or 215gm primer and 71.0 of I-4350. for real long range i would load A LOT of re-22 and 180accubond.

I shoot 70.0 grains of IMR4350 with 180 grain accubonds 2950fps. This load shoots 1/2 MOA in my gun.
