.22 Rifle Stovepipes... Cure???

I have a Marlin/Glenfield Model 75 (basically Model 60) that occasionally stovepipes a round. It's a very accurate gun, but the last time I took it out, it stovepiped 4 rounds out of 70 total.

Here are the only causes I can think of:

Load: I'm wondering if my load here is strong enough. I've been shooting up a brick of Winchester 40 gr HP (copper plated).

Recoil Spring: This is an older rifle, so I don't think that the recoil spring is too stiff. Could too loose a spring also cause stovepipes?

Extractor and Ejector: These look okay to me, but I'm no expert here. I suppose these are the likelier culprits though since the rifle is fairly old.

I suppose my question is this: Which of these is the most likely cause?

Or another way of asking is: In what order would you tackle the possible causes of the stovepipes?
 
I'd start with changing ammo. Although there is nothing wrong with the Winchester stuff, it just might not be what your rifle wants to eat. Remember, 22's are very picky eaters. That's the cheapest and easiest place to start anyway.
 
As a starting point, that makes the most sense to me as well.

Any recommendations for factory loads that work well? I know every rifle is different, but recommendations would give me a starting point.

I may head down to the ammo store and pick up 50 rounds each of several varieties. If there aren't any hiccups in 50 rounds, I'll buy a brick and try 500 rounds.

As far as the Winchester stuff, it functions flawlessly in my 22/45, so it won't go to waste.
 
I am partial to Remington Thunderbolts. That should cost you less than a buck for 50.
 
Yes, I had gotten Marlin to send me a manual, and just prior to this last outing, I had completely disassembled the gun and cleaned everything.

I don't really overclean my .22s. After each firing, I usually run Hoppes/dry/oil patches through the barrel with a length of weed whacker line.

After every brick of ammo (about every 500 rounds), however, I give them a thorough cleaning--involving disassembly, cleaning the bore with a brush, cleaning residue out with a toothbrush and Hoppes #9, wiping down all surfaces, applying a light coat of CLP to parts. I use RemOil in my barrels.

This rifle was clean last time I shot it.
 
Thunderbolts?

When Remmington first came out with their Thunderbolt 22 Ammi, I bought several bricks. I soon fooound they were less than desirable. Up to 7 out of 10 rounds would not go off.
 
The next thing that comes to mind is overlubrication. Semi-auto's don't work well when over lubed either. The next time you clean it---leave it dry and then go shoot it and see what happens---you can always lube it later.


Also---does it jam while you're rapid firing or during slow-aimed firing??

Slow aimed fire.

I do put CLP on moving parts, but after it has penetrated a bit, I do wipe them down with a dry rag. I know that CLP can gum up if left in copious amounts.

Who knows? Maybe different ammo will fix the problem.
 
probably the rifles extractor.i like cci stinggers for semi auto .22 they are a bit hot and cycle the action much better IMHO
