I've been shooting a Swedish M-38 for almost 20 years now and my Dad's been shooting one for over 35 years. Other than being a tad bit heavy we have NO complaints. I use it with 100's for 'Yotes and 140's for Whitetails. The accuracy is awesome to say the least, with any of those weight bullets out of our guns. I have also used 120's. I haven't seen any stability problems with any of those bullet weights at all, out to 300 yards, which is about as far as I have ever shot it at targets. ULTRA reliable and tough rifle. As for the Stevens , they're definitely lighter! I have only handled them at the gunshops and never fired one. I doubt the ruggedness and quality are comparable though. The Swedes make fine firearms! I'm sure either choice will do fine but if you want something that you can "abuse" in wet, freezing weather and still have function perfectly, I'd take the Swede hands down.
