I have a couple K31s, and haven't shot them yet, but shot someone else's a couple years ago. Yeah, they kick like a mule.
My shooting went like this:
BAM OUCH! ch-schk BAM OUCH! ch-schk BAM OUCH! ch-schk BAM OUCH! ch-schk BAM OUCH!
But they're supposed to be crazy accurate.... get one and pull the bolt out. Check out the machining on the bolt, and check out the bore. ABSOFUCKINGLUTELY flawless. I have one that was made in 1937, and aside from beat up wood, and fading bluing, the mechanical parts and barrel still look NEW.
I'm gonna try to get a few more... Hopefully one day these will go up in value. They're just pure bang for the buck right now.
The Mosins are great STURDY rifles, and ammo is dirt cheap for them. I need to get a 91/30, but already have an M1938 and M44. They're simple machines, but they are built like tanks.
