consistant jamming

[jraney]

hey folks, i have a marlin mod.60 .22lr it has a tubelar mag and holds around 16 or 17.Anyhow versince my dad has had this gun it will jam it may go 2-3 rounds before jamming it may go more but it always jamms. i have taken the gun apart cleaned and lightly oiled it and still the same thing. I don't want to sell it becuase then it would be some elses problem and i don't think that would be right know it has this problem. i also do not absolutly need it iether but it is very accurate, i would just like for it to work properly. do any of you have any suggestions on how I might be able to fix the gun myself, i don't think it is worth the money to have a pro do it. so if anybody has any thoughts other than throwing it away i would like to hear.

thanks

First, where is it jamming? Second I would recomend Rimfirecentral.com and go to the Marlin forum.

jraney,
Could you better define "jamming" in your rifle? I mean are the cartridges loading alright and the bolt won't close, so forth and so on. Also, is this condition created with a specific make of Rimfire ammo or does it do it with any/all ammo? And when you mention the rifle is "old,' how old? I've seen older rifles have difficulty with some of the newer made Rimfire Ammos that have thicker heads. If there is any sort of a buildup on the face of the chamber breech, that can also creat problems in bolt closing or even opening after being fired.

sorry i should have detailed alittle more. i would say the gun is at least 20yrs for sure, the jamming seems to happen with all ammo, shot fast or slow, from what i can remember (becuase it has been awhile since i have shot this gun becuase i have others that do not jam) it will jam on extraction and feeding. on the feeding it will run the nose high, almost like a stove pipe in an auto pistol. i plan to shoot this gun this weekend so i will be more observent and see where that gets me. also i am pretty sure this gun has done this from the time we got it. we did not get it brandnew, my dad traded another that had a broken stock for it, that gun also had problems. i suppose if the gun was not so accurate dad would have probably gotten rid of it along time ago. anyhow hope that helps.

this is a dumb question, but the rifle is lr only, are you trying any longs, or short?

The magazine tube may be in some way restricting the new round movement, that said, clean, spring follower etc. and i dont know

jraney,
Not owning a Marlin .22, it is difficult, other than to guess, possible issues that are creating your problem. And God knows I claim no expertise as a Gunsmith whatsoever. But Bheadboy may be onto something based upon your comments about he nose of the bullet "will run high." In order to eliminate or at least try to limit variables and the issue, have you tried to load rounds one at a time by hand to see if the problems remains or the rifle functions normally? If the issue persists whether the ammo is tube fed or by hand, then I'd look inside the chamber within the first 1- 2" and see if there exists a carbon build-up, called a "carbon ring." What prompts that thought is that you said the rifle works ok for two rounds and then "jams." That to me suggests heat in the chamber or feeding tube. Normally, a good brush and some elbow grease will remove carbon rings that tend to build up over time if the barrel hasn't received the cleaning that is needed to keep carbon rings from forming. Now keep in mind, I'm guessing of potentials issues because some rifles are rather unique with some issues and I'm guessing at universal issues that could be at hand. The only other thing I can think of is to seek out a Master Gunsmith who know Marlins and who can diagnose your issue if it is unique to your particular rifle. But I'd definitely check out Bheadboy's suggestion as a real potential cause of your problem. Good luck with that baby as I know first hand how frustrating some rifles can become because of small silly stuff.

Been down this road...... There's several little model changes over the years on the 60 so when you get there just be aware. The most common reason a model 60 will "jam" or stovepipe is the ejector being bent out of position. The ejector is if you'll look into the action with the bolt pulled back, the little "spring end" that's sitting on top of the feedblock. Usually the problem is it's fatigued and laying flat on the feedblock rather that sitting up a little which is how it catched the spent shell to eject it. There's some good threads showing pictures on rimfirecentral.com showing this. Only other thing I'd mention is, depending on vintage, the pics on rimfirecentral show the spring also bent slightly towards the right (ejection side). This is only correct for the later models. If you do this on the older vintage rifles it'll (the spring) jam the bolt.
