I have recently bought a Marlin 795 and I have put around 100 to 200 rounds through it. When I shoot it the gun is fine and everything but about every 15 or 20 rounds or so it will not cycle a round into the chamber and it will result in a "dry fire". Then i have to pull the bolt back to cycle another round into the chamber. It seems like it always does it on the second or third round in the magazine. Could it be my ammo or magazines or something else? I am currently using the cheap Federal bulk ammo. What do you guys think?
