I bought a K-31 awhile back, also picked up 480 rounds of mil-surplus ammo the same time. The ammo cost me $25 more than the gun.
Something I have always wondered about...I thought my Mosin M44 had a harsh recoil. My K-31 has more recoil than my M44, the K-31 is heavier, longer and uses a smaller round.
What makes the K-31 recoil harder, the type of powder or pressure of the round? Just wondering.
