Guys,
I bought an old Marlin Model 60 that works great with Federal Game Shok ammo, but everything else I have tried jams at least once in ten shots.
There are two main problems:
1). Failure to eject - the bolt doesn't recoil all the way back and the spent shell remains in the action. This isn't difficult to clear, just work the action, but it's annoying.
2). Failure to feed - the shell jams halfway up when it's being brought up from the tube mag. It ends stuck rear end up into the action. There are two ways to fix it. I can either push the shell back into the tube and re-chamber it manually, OR I can try to work the shell out of the action. This often leaves the bolt jammed backwards, for unknown reasons. That means I have to tear the gun down, free the bolt from its mysterious jam, and then re-assemble.
I'm guessing Problem 2 could be caused by a weak "lifter spring," and that the recoil spring behind the bolt could somehow be getting jammed and keeping the bolt held back sometimes (this is NOT a last-shot-hold-open gun AFAIK).
BUT
I have no idea as to the cause of Problem 1.
I carefully cleaned the gun before testing it. I didn't put much lube on it, as I didn't want to get it too dirty inside.
There's been millions of these guns sold. Someone else must have experienced similar problems and fixed them?

: did you mount a massive scope on it before the jams began to occur ?
