MARLIN MODEL 60 ?
Have a Marlin 60 that does not hold open after the last shot. When I miscount after 14 rounds and it clicks am I ruining the firing pin?

You have an older model, or you need to give it a good cleaning, or you are missing parts... the LSHO wasn't introduced until after they'd been in production for a while.
As to damage, what will typically happen with a rimfire is the firing pin will put a divot in the breech/barrel/chamber face, which won't let it properly crush the rim on a live round (after a LOT of dry firing).0 -
OK I bought it used and the manual says it has a last shot hold open. I'm not sure how old it is. S o I guess I will give it a good cleaning and work from there. Thanks for the info[:)] 0 -
Be careful when re-assembling it. There is a tinny spring that looks like it came out of a ball point pen that can kink real easily when re-assembling. 0 -

Expanding on what was already mentioned above, the last shot hold open feature wasn't introduced until 1985.
So there are zillions of guns out there made between 1960 and 85 that lack this feature. As I understand it, if your gun doesn't have it its either not possible or cost-effective to retroactively install the last shot feature.
Assuming yours does have the last shot hold open, as mentioned, dirt can be a source of your problem (and perhaps the most likely one), or a damaged or missing part.
Since take-down and disassembly isn't trivial with these guns, one easy way to clean them is to blast them out thoroughly with gun-scrubber (ie brake-cleaner). Obviously if you have the patience and ability to strip down the gun, that's better.
There are multiple videos available on the internet that will demonstrate how to do this. One is here (with a link to another on the side):

More are available on You-Tube.
In terms of what happens if you dry fire your gun, the firing pin strikes the breech of the barrel/chamber where the rim of a live .22 is supposed to go. While in some cases this can damage the nose of the firing pin, more often, the repeated impact creates a little divot or crater in the firing pin breech, raising up some metal around the edges.
The divot and raised metal, as mentioned, can prevent a good primer strike on a live round by not letting the round seat properly, though usually it takes quite a bit of dry firing before you get there.
Note that if you do get this problem, it is potentially repairable by carefully hammering/peening the displaced metal back into place and effectively filling in the divot.0 -
Dry firing a rimfire without a spent cartridge in the chamber is a no no . The firing pin will peen it's self short and may damage the breech also ! 0 -
Thanks to all[:)] 0 -
a trick I learned after bending two recoil springs.....
Take a ladys metal hair barret ond open it up and bend it almost straight. Using the end that is 'J' shaped , hook this under the recoil spring as your compressing it for re-assly. The 'J' hook will fit nicely between the two ears /slot in end of the bolt and allow you to get the spring fully compressed without bending at that last 1/2 - 3/4 inch. Once the spring is in you can slide the 'J' hook towards the rear of recvr. and remove the tool. Worked great for me and now the gun gets its full attention to cleaning and inspection. Hope this helps. [:)][:)][:)]0
