What are the differences between Mosins? I like the shorter one with the attached bayonet. Can the bayonet come off and hurt you if you fire it when it is folded. What is the difference in accuracy between the barrel lengths. Wast this an infantry and sniper rifle? How many yards are they good for? Is this considered the most reliable bolt action? Is it more reliable than a Rem 700 series? How many rounds could you possibly fire to ware it out?
