Buy both now while they are still relatively cheap. You won't regret it. If I had to choose I'd go with the SKS though.
Ya know, after getting other stuff, the 22 got boring, but when it was all i had i could shoot it for hours and not get bored.
It's about setting challenges not just firing rounds and boom..a 22 can be very challenging esp at longer distances..
Non of these make the gun more "user friendly".the sks is much more user friendly for a beginner than a mosin.
-less recoil
-lighter
-ammo is more common
-not so long
-lots of aftermarket goodies
