my friend has an old Remington 1100 semi auto 12 gauge that he's having problems with. he was at the range today shooting skeet. apparently at this range, you can only put one round in the gun at a time. so he would load a round in the chamber, close the action, and take his shot.

however, for some reason, the spent hull wasn't/isn't ejecting. he has to manually work the action in order to eject the spent hull. i don't think it's jamming or stovepiping. the action simply won't cycle and eject the round.

now, i'm not very familiar with the 1100, especially the old ones like this one. but my experience with semi-autos tells me that the spent hull should be ejected.

i'm wondering if a part is worn out or something. i'll be taking a look at it this evening and seeing if i can piece together what's going on.

anyone have any ideas or suggestions?
 
Skeet loads are usually very low powered, maybe too low for that particular 1100.

~ Keep your shoulder into it, no weak shoulders.
~ Use a 2.75" gun, not a 3" mag.
~ Make sure the Piston, Piston Seal and Barrel Seal are all clean, in good shape and assembled correctly.
~ Clean the barrel ring, that big hunk hanging on the bottom of the barrel, scrape all of the carbon off then restore the gas ports to proper diameter.
~ Check that the Action Spring Follower is not bent.
~ Check that the Forend Support is not broken.
 
good info guys, thanks. i think we may have found the problem. the gun says 3" magnum on the barrel. he was running 2.75" shells. he's going to try some proper 3" shells and see if that makes a difference. sounds like the 2.75" shells don't have enough power to cycle the action.
 
Some of the heavier Dram Eq loads may function the 1100 without the need of going to a 3" cartridge.
 
It is important to read the cartridge designation... not to just stuff in ammo that fits in the chamber...:D

That barrel is only designed to function with 3 inch shells. It may also function with 2 and 3/4 Magnum shells. It is not supposed to function with any lighter loads.
 
In normal operation the gun should fire a single round, eject the empty hull and lock open. It's actually the next shell from the magazine that closes the gun to cycle again.
It could be a number of things preventing the gun from cycling. First is this gun a field gun? Take the barrel off and see if it has one or two gas ports drilled on the underside of the barrel inside the sleeve. To get enough gas consistently, target barrels have two holes, barrels intended for field use have one. If this is a field barrel, it might work OK with heavier target loads.

Start out by giving the gun a thorough cleaning per this link. Remove the space in the "ht tp" to make it work.

One thing left out in this link is cleaning the recoil spring. To do this first remove the recoil pad. If you can't see how to do this it's because there are small slits in the back of the pad. Lubricate the shaft of a phillips screwdriver and slide it in and turn out the two screws. Using a LARGE screwdriver unscrew the nut. A tire iron may also work or a wood spade bit with the tip ground off. Slide the stock off and note the orientation of the two washers. Clamp the receiver firmly and push the plug at the end of the tube in slightly. You can now push the retaining pin out sideways. The spring is now free to come out the back and its under a LOT of pressure so be careful. Clean it, the tube, the follower at the front of the spring and reassemble.

As suggested in another post it may not hurt to replace the o-ring, piston and gas seal. The new piston and gas seal are now a single piece unit.

Now go try some shells. Does it cycle with faster target loads (1200 fps, 1-1/8)? Does it cycle with field loads? Get back to us if you are still having trouble. There may be other things wrong, but this should eliminate a lot of the normal problems.

It might, but it's not an absolute, The barrels are ported differently for the purpose of the barrel, the different port configuration changes the volume of gas needed to cycle the action . 3" barrels usually have one small port whereas Skeet barrels have two large ports. In addition, the Action Bar Sleeve of the 3" guns are heavier to help retard the action speed and unlocking.

No it is an absolute and you are 100% correct. A old style 1100 3" mag barrel will not cycle any 2 3/4 target loads.
You need to find a proper skeet barrel if you want the gun to function properly or re-port the mag barrel properly but then it will not cycle 3" any more .
He has the light receiver I would say since he didnot indicate it was labeled on the side magnum so the action barrel sleeve is not coming into play.
Wrong barrel is the problem for target shooting
 
Rereading this thread I see the OP later replied that the gun IS a magnum. That means the single gas port to allow the correct amount of gas, generated by 3" shells, into the action. Almost all target loads will not generate enough gas to cycle the action. Back in the day my magnum would cycle the Winchester Super Handicap shells (remember those rhino rollers LOL!). There is a slight chance the OP's buddies gun MIGHT cycle a similar load. It's worth a try. Most likely 3macs1 is correct and a new barrel is needed.

I still own two of them with the mag receiver one I shot ducks and geese with until the 1187's came out in late 86 the other still new never fired that I won at a shoot in probally 1980. Both came with two barrels a 30" VR 3" fixed full choke and a 26" VR 2 3/4 skeet choke.
The one I shot quite a bit at the time with the 3" barrel on would cycle 1 1/4 oz 2 3/4 loads from time to time but not everytime. 1 1/8 forget it.
Worked fine with the skeet barrel with most 2 3/4 however.
Both have some real nice wood on them and shoulder very nice for me
