That's odd. I don't think I've EVER heard of a Swede that won't do at least 1 1/2" groups... most are pretty much minute of angle. I don't remember if you said it had been re-barrelled... if so, that could be the issue. If not, I'd start looking for red flag stuff, damaged crown, damaged rifling at muzzle, ringed barrel, odd forearm pressure.. It should shoot better than what you are reporting.
