Re: New 6.5x.284 Norma build
Both of my 6.5x284's and 260 have a 1:8 twist barrel which stabilizes the 140 Bergers very well. I wouldnt go slower than 8.5 twist. My favorite hunting rifle, a 6.5x284 Cooper has a 26", #6 fluted barrel. It can easily achieve 3000FPS, the sweet spot for the 140VLD, carries well, has manageable length, and still has enough weight for 1000+ yard accuracy. The overall weight of the rifle comes in around 10.5 pounds.
