Twist Rate and barrel contour 7mm Wby Mag?

[McStern]

Dear all,

please give me your advice concerning the right twist rate for 175 grain bullets in a 7mm Weatherby Magnum.

My current barrel does not shoot well, so I will have to buy a new barrel. As I'll use the Mk V for red deer hunting in Europe, I will most often use bullets in the 160 grain class, most likely barnes etc. (I assume that traditional 175 grain bullets should have a comparable length to 160 grain copper bullets).

What twist rate would you recommend?

P.S.: what barrel contour would be appropriate for a "precise" hunting rifle?

thanks

McStern

As dave said, for twist rate 1 in 9", for contour Sendero .835" at the muzzle or heavier., and atleast 26"s.
