I need help desiding on what to do. I a'm going to buy a rem 700 vs fs II. Then I want to screw the barrel of and send it to Jim Hart. I want to build a 6mm br. I would like to know what twist would be good to stablize 90 grainers as well as lighter bullets. This is going to be a varmint gun. The reason for the vs sf II is the action and the stock. Any one out there have a varmint gun in this cal and what did you do? Thanx in advance J. Espo
