New barrel 4: Mk.V in 7mm Wby. Mag - length / twist / contour?

Hi all,

the bloo... rifle just will not shoot straight.
Therefore: a new barrel is required, BUT which length, twist rate and contour?

intended use of rifle:

- red deer / fallow deer
- <300 m (I know, it's not that LONG range)
- >160 grain (copper) bullets
- "mountains", e.g. Scottish Highlands, the Alps --> portability desired!
- max. 2 shots in short sequence (hopefully ;) )

Looking forward to your advice

26" (66cm)
#5 contour I went with a #6 contour on my 7mag, it's a bit heavy for packing around
1 in 9 inches twist (1 in23 cm)
Keep in mind the animals we shoot for food and display are not bullet proof. Contrary to popular belief, they bleed and die just like they did a hundred years ago. Being competent with a given rifle is far more important than impressive ballistics and poor shootability. High velocity misses never put a steak in the freezer.
