Twist Rates for high Elevation

[imohunting]

I'm getting ready to order a match barrel for a 7mm Mag and wonder what twist rate will work best for 168 or 180 grn Berger. I live at 7000 ft elevation and hunt up to 10k. Thanks

Berger has a Twist calculator on their site. You should be able to figure it out yourself.
