I just took possession of a 6.5x55 Swede barrel for my Encore and was wondering if anyone out there has real world experince with it in a Contender or Encore. I was going to get a .260 Rem. but this came along so I bought it. The barrel is 15 3/4" and I would like to use Nosler 120 gr. BT's in it, if I they will group, started out around 2700 or so. How much difference can there be in this and the .260 Rem. or the 6.5 JDJ. Enlighten me.
