Ditto, Iliwew, the Swede will comfortably handle the heavier weight rounds better than the .260. You just can't go wrong w/a 6.5 X 55. There's a reason it's been around for so long. Who cares about a long action? It's a moot point w/a single shot like a TC Encore. It's just a super efficient round, with a bonus: LOW RECOIL! Most any cartridge will do the deed w/any animal. Trajectories don't vary that much. Why beat yourself up with a heavy cartridge that, in the end, you'll wish you had a milder recoiling round. The Swede is one of the most sensible cartridges around. Period. You do your part, and the round will not let you down. And, in the Encore platform,...... need we say more? get yourself an SSK or MGM barrel, and you're set for an accurate, mild, and deadly cartridge for most anything you want to hunt. And, in a relatively lightweight package you can carry around all day long, without getting tired.
