My Remington 1100 won't eject shells

First off, just want to introduce myself. My name is Josh, I was raised in Alaska but currently live in Washington state (hope to move back this winter). I have been around all sorts of guns all my life, but just to shoot. I never had the initiative to learn much about them though! But better late than never, right? haha.

On to my problem/questions.

I have recently been given my Grand Fathers Remington 1100 shotgun semi auto magnum for 3 inch shells. This was probably the number one gun I shot when I was in Alaska (was always a favorite). And it had ZERO problems what so ever. I fly it back down from my last trip to Alaska, and it won't eject the shells. My friend had a large amount of Winchester/Federal, 2 and 3/4 inch shells and that's what I have been using (I'm about to buy some Remington). Anyways I was talking to some gun folks around here and looking online and this is what I came up with.

The reason my Shotgun isn't ejecting is because i'm not using Remington shells.

I'm not using 3inch shells. (Even though all I used in Alaska was 2 and 3/4 inch)

The shells aren't "Magnum".

The shotgun is dirty and needs a good cleaning. (I doubt this one)

Now what do you guys think? Feel free to add to the list. The Magnum part i'm kind of scratching my head at, I could find these rounds when people talk about them online, but never actually found any in person or online.

Thanks for any tips/advice/problem solving solutions!

Your gun might just not like them, they might not be loaded hot enough to cycle the action. My Beretta 3901 has problems cycling the cheaper Winchester and Federal game loads, but does fine with all others.

The most likely problem is the one you doubt, the gun needs a good cleaning 9especially the gas port). That and make sure the gas system is correctly assembled and the rings aren't worn..

Remington 1100's need to be kept clean and well lubricated ..to be reliable. If it were mine ...I'd clean it at least every 150 shells or so .../ or after every range trip to shoot clays.

If its clean and well lubed ...it should cycle most any shell that has a velocity of at least 1200 fps ....but they will often operate just fine ( again if they're kept clean ) on shells at 1150 fps...

The length of the shell is irrelevent....except that 3" shells are often loaded to a higher velocity. The amount of shot in the shell is irrelevent as well...it won't matter if a 1200 fps shell is loaded with 7/8 oz of shot, or 1 oz, or 1 1/8 oz of shot....its all about the velocity of the shell ...and the boxes you're buying should tell you velocity ...or at least the Dram Equivalent ( DR EQ ) and it should be at least 3 Dram Equivalent .

gas operated guns...do not run dirty very well..../ or any gas gun for that matter....especially old technology like the 1100's ...some of the newer gas guns like Beretta 3901's, Browning Silver series, Winchester XP's ..will tolerate less maintenance. If you don't like to keep a clean gun ...then look at an inertia operated semi-auto ...like a Benelli. Inertia guns run much cleaner - because the gas is not used to cycle the action.

Get someone to help you take the gun apart / show you how to clean it properly ...and my hunch is, you'll enjoy owning the gun more ...and understand how it works better. Its part of the hobby ....

here's all I do to clean my 1100 LT-20. Like Big Jim said, I let no more than 100-200 shells ignite in the gun, then I strip and clean it immediately. It's best to shoot an 1100 semi-dry. All I do is remove the barrel and forearm, pull off the two rings and rubber O-ring. I rub off any gunk on the recoil tube with 00 steel wool and the action bar. I will then spray a little bit of G96 or Break Free CLP on the recoil tube, action bar and gas cylinder that is attached to the barrel. Then wipe everything off with a clean rag, then reassemble. Oh yes, use a pipe-cleaner to ream out the gas ports so they remain void of crud.

I only clean the trigger group once a year with a blast of Gun Scrubber. That should do it for you...

when I said clean....I meant clean ......not leave the trigger group in it for a year....come on Slugo ...geez man.... It only takes 30 sec to drop the trigger group out ...use some Q tips on it and a little solvent on it ...some compressed air in it to dry it out ...and you're done...

and slugo and I disagree on running a gun "dry" ...I run my semi-autos on the wet side of dry ....not so it drips off the gun ....but a good oil lube ...like Break Free ...or maybe Wilson Combat Ultima Lube Oil ....are both good products...even Rem Oil is ok ...or I like Rig Oil # 2 in a trigger group too...

Slugo and I basically agree...just not on the oil / ....but you get the idea !

I agree with you, boss!! That's why I said semi-dry. I leave a thin film an most of the critical areas...

I know we disagree... but if a little bit is good / more has to be better...its mother natures way of making things right ...( 1 shotgun is good , 2 is more better ...same thing ...) ....

but ok - before we tire this young fella out ...we'll agree to disagree...

Magnum versions have 1 gas port versus two, if it is the slightest bit dirty, that explains your ejection issues. The other reasons you mention have no basis in fact

Do NOT get any lube on the O-ring, they brass pistons are designed to run dry.

"If it rattles, it's a Remington" is the old saying

Thanks for all the input guys! I read a whole bunch of how to's on cleaning the gun, and have just done so. This is something that I will NEVER get rid of, it's more important to me because of who's it was, rather than what it is.

Hopefully I go shooting again soon though! So I will know for sure, i'll also buy some Remington shells, along with bringing the Winchester/Federal rounds, to see if that makes any difference as well.

Once again thanks to you all! Always happy to be apart of a good working Forums such as The Firing Line. You can count on me coming back with more questions!

The 3" 1100 Magnum was designed to shoot 3" and 2-3/4" MAGNUM loads only. Some will shoot lighter loads but don't bet money. If you want to shoot 2-3/4" field or target loads reliably get a 2-3/4" barrel.
BTW, a 3" load generates a longer pressure pulse, not higher pressure.

Replace rubber O ring

Had same problem with my Remmington 11-87. I had it perfectly clean and it would not cycle.

Replace the rubber O ring for the gas operation system. They get old and get little cracks in them, get brittle... in short they stop sealing properly.

I relaced mine and my 11-87 worked perfectly from that point and cycled ALL types of shells regardless of load or length. Hope this works for you. I ended up selling the gun after a few years, never had to replace the O-ring again, but I think its common to do this every few years depending on how often you use it.

PICTURE OF VASELINE PETROLEUM JELLY


_______
....

...as you can see, I'm not smart enough to copy Slugo's post with the pic. of the Vaseline jar.

I will say that using petroleum based lube on many 'over the shelf', common o-rings made of natural rubber, butyl or silicone is not a good idea as the petroleum actually harms the o-ring.

If you want to use a petroleum based lube, the o-ring should be made of nitrile or Flourosilicone(to name a few).

Too, watch your cleaning/lubing agents when the agents come into contact with many rubber parts. Some of these agents just are not designed to be used on many rubber compounds.

Example would be PB Blaster.

Spray some PB Blaster in a container, drop a butyl or natural rubber oring in the Blaster for a couple days and watch what happens. O-ring swells and will eventually become very soft.

FWIW, I've replaced all my 1100 o-rings with ones made of nitrile. But you have to ask for them as most will stock/sell you a natural rubber or butyl o-ring.

There are many elastomeric compounds that are impervious to petroleum based lubricants, including Viton which is what is most widely recommended and sold for 1100s/11-87s. Nitrile and Buna-N are less likely to hold up. Neoprene is available from industrial suppliers, but who needs 50? I have one that has been in the gun, and shot heavily, since about 1967, and it is still fine. Ham handed cleaning is the most likely O-ring killer. The ones you see advertised as made of Teflon are not in my limited observations, which is good because Teflon is not very elastic. If you want it to look gray and shiny like Remington's, put the Viton ones in a sandwich baggie with some graphite lock compound and shake.
Many 1100s will cycle okay with no O ring at all installed, in fact one of my three will with 1-1/4 oz or heavier loads.

I replaced mine with Viton - a great compound, BUT, I still did not use ANY lube on the mag tube or brass rings - it doesn't need any

V-in-LA, You are correct to advise on the Viton o-ring but I would like to know why you feel the nitrile o-ring won't last in the 1100 application.

The Viton is more heat resistant and impervious to more chemicals then the Nitrile but I've not found a gun cleaning or lubing solution that negatively affects Nitrile.

Also Viton is not really recommended with ester or ether solvents and if I remember correctly, cleaning solvents such as Hoppe's #9(and some others) falls under the ether solvent list.
Nor do I shoot my 1100 enough to generate enough heat to distort the nitrile o-ring.

Too, about 4-5 years ago, I ordered o-rings from Rem. for my 1100's as well as two of my brothers 1100's. I was sent a packet of 10ea.(if I remember correctly) o-rings which were silicone o-rings. Was a bit surprised and didn't use them.

Went with the nitrile instead.

the Vaseline was a joke! The rubber O-ring needs nothing applied to it...

In a response to the article in http://www.shootingtimes.com/gunsmit...0loads_200808/ By Reid Coffield... I wrote:

Overall nice intro to the venerable Remington 1100, but more on the history than the problem. Not to be harsh, however I have spent the last month working on an 1100 from the mid 70's and have been exhaustively researching every possible reason why my gun failed to cycle reliably with Federal, Winchester bulk 100 ct boxed loads, Winchester AA's and Remington Gun Club. all ounce and an eighth loads.

I broke the gun down and did a super cleaning of it, the action spring tube the magazine tube, and all internal parts were removed surgically cleaned and properly lubricated with lithium grease (only requiring a very thin film to be effective) and re-assembled to find that it still failed to function more than a couple times. That in itself was curious. Why would it function for the first few rounds fired, then return to not ejecting spent shells?

I had replaced the gas piston & seal, and installed two, not one rubber "O" rings to keep all the gas inside the mechanism. I also replaced the Bolt buffer which was broken, and I checked for any debris in the action spring tube, and inspected the follower (which guides the "harp" to operate the action,

Called Remington on Wednesday and spoke with "the 1100 expert on duty" who said I had done everything he would have done. But raised the question of the ejector. On my vintage gun the ejector is a punched in section of the barrel extension that produces a little bump in the position where the bolt has a recess. It was shiny, but still protruded about as much as the dimple on the other side..

After failing to work again this morning, I spent one last time looking for the answer and found a photo showing the inside of an 1100 for sale, and it had a very prominent ejector. Voilla I thought this is it... I have posted the photos here showing the difference. It is significant... and I believe is the problem.

Not the gas port size, which is close to .083" But the silly excuse for an ejector on my old gun's barrel. I would bet that a different, newer barrel would function perfectly. And my biggest burning question is WHY didn't Remington know this, and offer it as the first thing to look for when I mentioned the manufacturing year of my gun.

Shame on you Remington.

Yes there is a plethora of problems that can cause failure to eject, but Remington should be able to provide guidance when called upon... what is your serial number, and is the barrel original, or what is the code on the barrel... all could have easily produced a positive result and ended the dismay I was feeling.

I'm a retired Telecom Engineer, and approach problem solving in a very structured way. I always get my problems solved, and usually early.

Keep your powder dry...

Well I am a retired Professional Mechanical Engineer, who spent the last 30 years managing industrial engineering and maintenance departments and being the number one troubleshooter on sites, and I have 30 years plus of working on Remington 1100s (and other stuff) as a licensed FFL. I never called myself a gunsmith because wood hates me, but I am a fair hand at gun mechanicing.
If the bolt is cycling properly, you only need that little bump to kick the shell out. It doesn't have to grab anything, just intersect the base circle of the shotshell. If you cycle the bolt manually with a shell - loaded or unloaded - and it kicks the shell out you're fine. And if the ejector button was worn, why did it work for a few rounds and then stop? I have rarely found mechanical issues to behave in such fashion. If the bolt is cycling and the shell is not ejecting, check to see if the extractor is chipped or broken. Only part (and only one of them) I have ever broken on six Model 1100s over 50 years and a couple of hundred thousand rounds.
EDIT - with some of the cheap steel based shotshells the base may grip the chamber so hard the shell will not eject until after it has cooled, if then. The chambers on mine are like mirrors and my guns will run even the Winchester Universals, but they rip about half of the bases doing it.
If the bolt is not cycling, it's a gas system issue or something is binding. A piece of masking tape on the receiver across the ejection port behind the handle will quickly tell you how far the bolt is moving.
The standard gas port size on a 12 gauge is 0.079" (2 ports). Magnum is 0.073" (one port - pre Steel Shot barrels), and Skeet is 0.086" (two ports) - with an admonishment not to shoot heavy loads. Check to make sure the ports are open with a drill bit turned with the fingers. A Magnum is designed to shoot 2-3/4" and 3" Magnum shells. Some will do better, some won't, and shells can make a huge difference, even if they have the same weight of shot and velocity. The pressure curve is the thing. I have a Magnum and it used to shoot any 1-1/4 ounce field load, but not any more because the shells have changed.
On older guns with a lot of use OR neglect, it is not uncommon for the outside of the mag tube to be worn. With the old style (original) gas piston and piston seal, they compensated somewhat for wear and still sealed, but the new snap together parts can be problematic - they are no doubt cheaper to manufacture, but in my opinion they do not work as well. Any new O ring should suffice to check it out, but as noted earlier for long life use the right stuff.
Remington used aluminum action spring followers for some years, and the grade/quality of the aluminum varied. It it becomes misshapen the follower can drag in the action tube and cause malfunctions.
If the fore end support (12 gauge) becomes bent it can drag on the action bars and cause malfunctions.
All I used for 20 years was WD-40, and that was when I was shooting competitive Skeet, and it worked fine. I now know there are a lot better alternatives, but the choice is not critical as long as it isn't real cold. Gun oil is the most overthought subject on the internet. No wait, it's tied with motorcycle oil. I spray my gas system stuff with RemOil and then wipe off the excess - I call it damp. Some people run them dry. Some people run them soaking wet. To be honest they all seem to work for the people who like their method.

Clean it and run 3 Dram loads. Some of the light target bulk stuff from Federal and Winchester is just a step up from trash. Soft hulls, separated case heads. Both Win and Fed make better shells too though.

I know some guys are bickering about dry or wet on the 1100s, and I will tell you what two different Remington sponsored shooters, with world champion credentials told me.

"Run the 1100 as wet as you can get them, and then add a drop."

AND

"Run it as dry as you dare. A dry lube is best if you must."

I have tried both ways and run well over 1000 rounds each way. A light coat of oil, could never get past 500 without malfunctions starting on my 1100s.

Most of that garbage IS 3 dram, which in today's world means not a whole lot.

I'm voting for partially clogged gas ports or worn piston parts. I owned an 1100 in 28 and when it ran well - like a Jaguar - it ran great; but when it hiccuped, you'd have better brought a second gun to finish.

BTW, there's absolutely NO reason for two O-rings.

LOL...I accidentally cut a few O-rings over the years.

Yes, a lot of the junk loads are 3 Dram...so to be clear to the OP, don't run Fed or Win bulk pack ammo in your shotgun.
