Marlin model 60 malfunctions

[Booshie]

I've been having problems my Marlin Model 60 failing to eject a spent casing. This has been happening fairly often (usually at least once every 20-30 shots). I inherited this rifle from my father, so there's no telling how many rounds have been ran through it, or how often he cleaned it. When I first encountered this problem I thought it might be because it was dirty (it was really dirty), but after taking the rifle completely apart and thoroughly cleaning it, it's still having problems.

I've shot 2 different brands of bulk ammo through it, both with the same result. So my question is, could it just be cheap, bulk ammo, or is there something wrong internally with the rifle? Does this happen to anyone else?

These photos were taken after putting ~20 rounds through it, right after cleaning it.

Thanks

Odd my model 60 would eject em while it was so dirty the bolt would have trouble moving. Might need a new extractor spring.

bulk ammo is your problem. older ammo that worked great in these guns had a differant pressure curve. most model 60s will have SOME issues w/ bulk ammo, some more than others yours being the latter.

keep it clean and stick to high velocity 40 grain stuff to increase back pressue. mini mags are all that i have found that will run through MOST model 60's on any sort of consitant basis.

i have been tempted to try to make a longer lighter recoil spring to allow the action to cycle easier, or lightening up the bolt w/ the existing recoil spring.

the second picture also makes it look like you need a new extractor.

There is a section dedicated to Marlin semi-automatics. You may have to wade through a lot of stuff but I'll bet you can find some help there.

I can see the problem in your second picture. Your ejector is out of position. It needs to be tweeked as per these instruction. No special tools, only takes a few minutes.
