remington 1100 problems

02 May 2010, 23:56

I have a remmy 1100 that really doesn't like 1oz loads(28gm),but it will cycle the 1.1/8th(32gm) loads no problem.
Unfortunately the powers that be will only allow 1oz(28gm) loads for competition, is there any way I can alter the gas vent to allow more gas through for lighter loads?

I have heard 1100's usually need to have the O rings replaced.

Griff, before you do anything to the barrel ports, you might try a faster velocity "sporting clay" type load. A 1 oz. load going 1,300 fps or better (3 1/4 dram. equiv.) should function in a Rem. 1100 without modification.

I don't think the rubber O-ring is the problem if you've examined it and it works well with other loads.

Rem 1100's deposit a lot of carbon and gunk around the gas rings and barrel seal(o-ring)and the magazine tube. Thoroughly clean these areas and oil the magazine tube sparingly with Break Free. Also replace the barrel seal with a factory made seal not some substitute. The fit is critical. Make sure the seals are assembled in the correct order.

Thououghly clean and lubricate the action. Then take a wad of stainless steel pot scrubber, wrap it on a wooden dowel, put it on an electric drill and scrub the heck out of the chamber.

It should handle the lighter loads then.

thanks for the replies.
I have replaced the seals with one of these new stainless ones,I was told that that they are far better, or was that just a salesman's pitch.
What would be gained by the cleaning of the mag tube?
Brownells do a replacement part which supposedly aligns the cartridge better,would this be a help, also a new stainless spring system might help, but how the hell do you dis-assemble the magazine tube..

Your 1100 can be tuned to fire 1oz loads by modifying the gas port; however, this can't be reversed and will make firing heavier loads possibly damaging to the shotgun. I'm pretty sure there's a chart in one of the Gunsmith Kinks books showing port size in relation to barrel length; that might be a starting point for opening up the gas port. Once you're certain the rest of the system is in good order, and the 1oz loads continue to fail to cyle the shotgun, opening the gas port up is what you'll need to do.

Remmington made lots of swap out barrels for 1100s.
If you do go forward with the barrel modification, and also plan to use that 1100 for othr loads, then get one of the original Remmington barrels to use. One barrel can be modified and the other kept as original.

I agree with DaMan and Tebsinar. Just wou have to carry a 1oz payload doesn't mean it has to be a wimpy one. Try stepping that up first. It worked for me. Like Tebsinar said, if you open the ports, make sure it is on a replacement barrel. It is too cheap not to.

I imagine the stainless seals would be easier to clean the carbon off. Though I've never had any trouble with the factory seal (except the rubber o-ring) which needs to be changed from time to time).

The outside of the mag tube is what the action bar assembly rides on. Clean it and LIGHTLY LUBE after removing the action bar and bolt.

Clean the bolt and pay special attention to any carbon on the INSIDE of the action bar. LIGHTLY LUBE.

I recommend that you NOT remove the trigger group unless it's really crudded up. Remington did not stake the feed latch and it's harder than hell to keep it in position while reinstalling the trigger group (trust me, I re-learned this lesson this morning).

Always keep the trigger cocked and on safe when removing the trigger group or action group. If the trigger falls, it creates a real PITA to get it cocked again for reinstalation of these groups.

During routine cleaning, clean the two gas ports on the barrel using pipe cleaners and solvent. Also get all the carbon out of the locking lug on the barrel. Then clean the seals and reinstall in the proper order on the mag tube.

And finally, make sure you have the mag tube cap on tightly. When you're tightening the mag cap down, you'll hear detent ball clicks. Tighten it down till it doesn't want to procede to the next detent using REASONABLE FORCE.

It'll help the Brownell's and the parts makers finance their kids through college!

DO NOT REMOVE THE MAG TUBE FROM THE ACTION!

One thing to look for on the 1100 12 ga. was the locking bolt hitting inside the top of the receiver where the barrel extention fits up against the cut out of the receiver. If it is leaving marks at this point you will need to remove metal where it is hitting to make the receiver to the same level as the inside of the barrel extension when in place. This was a problem on some of the receivers in the 1980's production. Determine the size of the original gas ports and make up an extended drill and run the drill through to clean out the carbon. I would use grease inside and not oil. We used Rig grease when we were doing warranty on the shotguns. Leave the magazine tube dry after cleaning it with kerosene.

I had a light small frame 1100 20 ga. that caused lots of problems until I found that the silver solder had broken loose on the action bar and the bolt plate. Resoldered and it worked like new. It was failing to eject about 1/2 the time.

Griff has asked me to post the pictures below to illustrate the issue.

Jon2,

Take a picture of the inside of the receiver where the extension butts against the metal. Take one without the barrel and one with the barrel in place. If it is hitting the receiver you will be able to see the metal deformed.
