Marlin Model 60 Strange issues

[bigreave]

I have a Marlin model 60 made during the clinton years longer barrel than mag tube great truck plinker rifle . I always shot cheap federal ammo never had a problem, i switched over to remington high velocity and the gun jammed like i never seen and the tube mag plunger got stuck in the action and i managed to dissamble the gun and get the plunger back out but it was really bent . I know the ammo prob didn't cause this but it all happend the same time . I'm having a real hard time trying to find the right mag tube length , i have found 3 diff sizes ?  and what would cause the plunger to get pushed all the way in the action ?

sounds like the carrier spring broke.

if I may ask, where did you find 3 different length tubes? I am making a short, lightweight 60 for my son and i would like to shorten the tube as short as possible, so i can shorten the barrel to 16 1/4.  Thanks, Dave

For a shorter magazine tube, might want to check Numrich Gun Parts to see if they have a tube for the Marlin 99 M1 22 rifle.  Marlin 99 series was forerunner to the model 60 and externally they are very similiar.  The 99 M1 was a short barrel rifle that was suppose to remind you of a M1 carbine.  Its mag tube holds about 10 rounds and is around 11 inches long and possibly it would fit a Model 60.

Interesting article on a guy that shortened his model 60 himself.

I am starting to wonder about 22 semi-auto rifles.  I acquired a used Model 60 and cleaned a lot of crude out of it.  I went to the range with Blazer LR ammo and it had two or three miss fires out of three boxes.  I was not happy with the performance and was blaming the ammo.  The next trip I had Federal Lightning LR ammunition and the failure rate was very high.  I gave up that day.

I returned to the range with a bolt action 22 rifle and the same box of Federal Lightning.  There were no misfires, ammunition was accurate.

More interesting was a Remington 22 automatic owned by a friend.  A couple weeks ago we took a number of firearms to the range and he had a very nice Remington Model 522A.  He has had this rifle since new.  He suffered a number of miss fires with CCI ammunition.

Back in the late fifties and early sixties I burn a lot of .22 LR ammunition in a Stevens autoloader without a failure.  And the same goes for a Ruger 22 pistol.  I took this cat with three quick shots from the Stevens.





I had the Model 60 out today.  I pulled the trigger group, and it appeared clean.  I lifted the bolt about ½ up on the front end but did not remove it.  It appeared clean under it.  I sprayed the trigger group and the bolt, and bolt bed with WD-40 and it soak a couple of hours.  It already appeared clean.  After the soaking I blew the areas out with high pressure air.  I followed up with a light lubing using Rem-oil.  I paid special attention to what I will call the rails or the surface the top of the bolt rides on.  When I disassembled the rifle they appeared dry.

Having read the cleaning instruction more closely it appears that I needed to take the cleaning a little deeper and pull the bolt out as described.  When I received the rifle it was full of crude.  I believe the rifle was fired a lot and then stored for years by its elderly owner.  The recoil spring and guide appear to be free of crude.


Interesting firing the M60 with double hearing protection on.  I use foam plugs and then muffs over my ears at the range.  When I fired I am more aware of the M60 action working than the report from the muzzle.

I have made these magazine tubes from standard steel tubing.  On the crimped end, take a tubing cutter, and file the edge off the cutting wheel until it's blunt and make sure it's still round.  As you slowly tighten it up, it will crimp the tubing to hold the plunger and spring in.

I have made at least two this way, one for one where the tube was missing, and one that was bent.
