Given comparable action strengths, the 6.5x55 and the 260rem are kissing cousins. I've shot moose, deer, elk, bears and coyotes with the 6.5x55 from both m38 swedes and coyotes only (so far) with a Tikka T3. I prefer the T3 for the added velocity, but wouldn't feel undergunned with the swede. The real secret is, "it's not how big your bullet is, but how well you can shoot it". The 260rem like the 6.5 x55 swede has very mild recoil, even in a model 7 remington. If you have the trigger pull taken down to 3 pounds or even less, it's capable of fine accuracy which will usually mean more confidence, which relates to better hits on the most vital areas of the game you're going to hunt. Go ahead and get one, just don't let your wife shoot it, or you may have to buy another one. Stick with 140 grn bullets Hornady, Speer etc or for premium bullets Like Nosler or Barnes, 129 grain bullets will do just fine for deer. One more thing, practice makes you a better marksman, shoot a lot at different ranges and get to know your gun and where it will shoot instinctively at any range and under different crosswind conditions, don't depend on books for drop and windage indication. When I was first starting out a great old gentleman took me under his wing and beat this into my head. He had me convinced that the 303Brit was the "be all end all" and if it wasn't for my insatiable urge to try out every new calibre/rifle/scope/trigger etc etc, appetite, He may have been correct. bearhunter
