Was surfing around the other day stumbled upon a thread in this site about the m717 blowing up so to speak, I think it was by a t george back in August and I find myself in the exact same situation. My Marlin is doing the same thing.Ive read of other people having same problem, one person called Marlin they said bad batch of ammo, one was using cci some elly I was using Hornaday - is all ammo bad ???Seems this is a common problem, Anybody have any new info on this problem would love some answers - love the gun really hate to give it up !! Thanks
