Remington 550 trigger and ejection failures

[sack]

Well, I plunked down some bucks for a rifle Friday, and find that I have a "project" instead. Along with a crappy ejection problem I have a trigger problem:

The rifle does not always fire when I pull the trigger. The trigger comes back, but no resistance is felt, and gun will not fire. The trigger does not seem to be reliably engaging the sear, perhaps? I can eventually get the rifle to fire if I release and pull the trigger again. Applying sideways pressure to the trigger (in either direction) might be helping, but not reliably. Any advice?

Problem #2 - ejection. The rifle seemed to eject okay for the first 30-50 shots, then -frequent stovepipes or the empty stuck to the LEFT of the round entering the chamber (away from the ejection port). I have since given it a good cleaning, but cycling the action by hand reveals variable resistance to pulling the bolt handle back (sometimes it goes back easier than other times), and sometimes clicking, but not most times (what's up with that??).
As you may know, the 550 has dual extractors left and right. They seem to be in good shape. I don't know enough about how ejection is supposed to kick the empty to the right - is the left extractor supposed to pull out? I don't see a mechanism to make this happen, but I'm no gunsmith. I'll shoot her again after the cleaning, but any advice is welcome, please.

Another question occurs to me - this rifle was a consignment purchase from a local gun shop. I did not ask about guarantee. Would one expect any failures in function to be disclosed in a case like this?

The 550 uses a Williams floating chamber to allow ejection with low powered .22 Short & Longs.

You need to remove it from the barrel and throughly clean it of carbon fouling.
ONce you take the bolt out, you can pry the floating chamber out of the barrel with a small screwdriver blade.

As for the trigger problem?
It may be related to the carbon fouled floating chamber is the gun is not cycling all the way back to reset the trigger each shot.

Thanks. I removed and cleaned the floating chamber, bolt, etc. I'll let you know later if it helped.

Remington 550 trigger does not catch sear

OK, the ejection issue was solved by aggressive grinding of the left ejector. The trigger issue is harder for me to understand. I am not a smith, and the innards of this rifle are pretty shielded from view. Through a hole in the left, I can see that when the trigger is pulled, it will usually not grab the sear on the first try; it gets zero to partial purchase and just slides down the back of the sear without pulling the sear down. If I pull the trigger a few times, or wiggle the bold handle some, or take the stock off and push up on the carrier, it allows the hook of the trigger to get properly on top of the sear. Then it will fire fine. I am tempted to file that trigger hook off a bit to make it easier for it to get on top of the sear. My other option will be to take the trigger/carrier/sear/springs out for a good look-see and cleaning, but the sear case cross-threading issue has me a bit spooked. Any good advice out there?

Go to remington forum on rimfire central forum ask there several 550 experts there. I have a 550 it was giving problems changed main action spring helped my 550

Thanks Bull. I cleaned the trigger thoroughly and took just a bit off where it contacts the sear. Seems to work fine now IF I pull the trigger a bit to the right to get reliable trigger-sear contact. Pulling straight back, the trigger still does not reliable engage sear. I'm happy the way it is now. It's not perfect, but it's not difficult to start the trigger to the right when pulling it, thereby getting reliable engagement.
