He's been tossing the idea of a bolt-action rifle around for a few months and has been asking me some questions. He has pretty much decided on buying a Tikka T3 rifle with a 20" barrel. The other choice is .308 Win which I like just fine and think it would suit his needs fine, but is the 6.5 worth it? I know the Swede is flatter and with lighter bullets can get over 3000fps velocities but it takes a hit in muzzle energy compared to the .308. He has said he would like to possibly hunt longhorn sheep with it someday, I figure either caliber would be perfectly fine for such a task since Scandinavians hunt everything with the 6.5. I know we have at least one Swede shooter on here, any insight would be greatly appreciated. As a side note, if I had picked up a Swedish Mauser before I got some of these other surplus rifles, my Tikka T3 in my safe would almost certainly be chambered in 6.5x55.
