My marlin has recently started to occasionally half cock when cycling the action.I'm not aware of short stroking it and the empty is always ejected.The only tampering i've done recently was to reprofile the hammer to give a rounder top to smooth up cycling and also tweaked the trigger safety block spring.
So what of these 'improvements' if any is likely to give this problem if a little over done.

TVM.

How exactly do you mean,half cock??

The rounding the hammer has reduced the height to the point that the cam on the base of the bolt does not fully connect with the hammer in order to drive the hammer to full cock.

The empty case will be ejected because the bolt is travelling the full length, but the bolt is riding over the hammer. I'm imagining you are having to manually cock the hammer for each shot or is it intermitant?

Should have bought a Rossi. :lol:

Yeah, like you should get something in synthetic and stainless....... :55:

I've a Sako TRG 22 Tarts gun for sale at the moment.

Probably never sell though. :(

Mr S, just read your post again and you say "occasionally" only half cocks. Yep, I'd say it's the runding of the hammer that's causeding it. When yu cycle the lever on a Marlin, apart from the obvious rearward movement, there is also a tiny amount of play laterally and vertically, all depending in which direction and how much, pressure is applied to the lever during the cycle. You'll never get to replicate it exactly the same, stroke after stroke.

I reckon the rounding of the hammer is not square and so not being fully engaged by the cam, depending on how the pressure is applied to the lever........

Much the same as my first answer.......!

An outstanding rifle. :cheers: But sorry, doesn't count. It's obviously stock and not "yours" per se!
:-P

Of course it isn't! What kind of shooting slapper do you think I am? :x

The same thought i've had from elsewhere,was hoping it might have been the spring(cheaper).

Thanks all the same. :goodjob:
