If you want a great shooting surplus rifle, pick up a Swiss K-31. I have 3 of them, and an older 1911 swiss long rifle. My K-31 will put 5 shots of surplus or reloads inside 4" @ 100 yards. Ahh yea thats open sights too, no scopes.
The 7.5X55 swiss ammo is more money than the mosin ammo, but the rifle is a work of art, very smooth straight pull bolt action, 2 stage trigger, detachable box mag, and great barrels because the swiss never used corrosive componets in their ammo. I didnt pay over 125 for any of my K-31's. Had I drawn an elk tag this year I would have hunted with it.
To use the words Mosin and SKS in the same sentence is doing a great diservice to the SKS, and I am in no means a fan of the SKS. I have a 91/30 and as said its a rough, hard to operate POS. I hammer the crap out of it, never clean it, just sit on top of the hills blasting ammo out of it. Get it so hot the cosmo is leaching out of the wood, throw it in the back of the truck and drive home. It is the only real POS rifle I have in my collection, and I treat it like one! Save the cash get something else, unless you need something to drive tent stakes with.
