It is a fantastic rifle cartridge. It doesn't get the press that the 7x57 does in Africa, but I would say there is hardly a lick of difference between them in practical effect on game. I have a Ruger M77 MkII that I have done some work to. It shoots and looks great. I don't push my loads hard at all and it kills like a hammer on medium large game. Like less than 250-350 lbs. It will kill much larger animals, but don't expect them to crumple like they were just bludgeoned by a four ton pile driver. If you don't reload, most factory loads for the swede are anemic at best. They are slow and only really would have an effective range of 200-250 yards on animals (Not the range you can hit them at but the range at which the bullets readily expand).
If you really wanna see what the Swede will do, you need to reload it. It has more case capacity than either the 6.5 creedmoor or the .260, it is more heavily tapered so it feeds like its covered in Teflon and it's chambered in long action rifles so it can make use of its entire case capacity because so little of it is obstructed by the bullets impingement. Mine is probably the most accurate rifle I own... Its sort of boring shooting it at the range honestly. You know its going to put all the bullets exactly where you had the crosshairs and there is no sinus jarring concussion or headache inducing recoil... pretty boring really. Its a mathematicians rifle. Dry, boring, predictable and works every time. It really is one slick little cartridge and I will never part with mine. I guess with firearms, you don't want them to be too exciting or you end up missing fingers or with a detached retina...
