Yeah Ford, it has been slugged multiple times & the barrel stamp is >>6.8<< mm. I have a couple lying about and am going to try to work up a load between the group.

A 6,5X70R Pencil Case will hold 35 grains of VV N 140 and I expect a load to be something like 10 grains less.

I would say Most Austrian 6,5X70R chambers are going to be in the >>6.8<<mm to >>6.88<< mm range. A skosh larger than their German Cousins.

Hochachtungsvoll,
