A friend has a Browning 2000 semi-automatic 20 gauge and it will not cycle shells. It fires the first shell and the hull gets stuck while trying to eject. The second shell is being released from the magazine tube and is also pressing up against the hull of the first shell. We took the gun apart and cleaned and lubricated it with G96. The gas port is correct as shown on the diagram. Tested with a selection of shells from target load to 3" heavy loads. Correct me if I am wrong, but I believe this model was problematic for this issue.

Any ideas? Thanks in advance.
 
I don't know if this applies to the 20 gauge, but for a 12 gauge, you need to use the properly sized barrel. 3 inch won't function in 2 3/4 and vise versa. Merely tossing this out there without any extra knowledge to if it applies.
 
I typed in "Browning 2000 Ejection Problems" in the Google bar and some interesting problems came up.
Might be worth the read.

I ran into this with a buddies Winchester 1400 and found the gas port holes in the mag tube ring plugged.
 
Thanks for the advice. I am going to read through the search results and give everything a try starting with the gas ports. When I took it apart with the owner I know we did not check the ports, but only took the piston assembly apart and cleaned it.
 
Well - I recently was given a 12 g B2000 with similar issues, I thought I'd try to fix it for my duck hunting buddy. Not being familiar with the mechanicals, I sought out the service manual. As they used to say in engineering school, these things are "geezly f*ggin complicated". I gave it back to my buddy, telling him so...
 
Check to make sure the little rubber washer is in the mag cap, had problems with a 12 gauge once and ended up that washer was gone, replaced it and all was fine.
 
The gas port is wide open so that can be ruled out. The mag cap has a hard rubber/plastic piece in it that is about 1/2 to 3/4" deep. Is there also supposed to be another washer similar to the size in a garden hose??
 
That cap is not suppose to leak.
Wander over to the Brownings site and download a manual and read thru it.
You might find the info on what is right/wrong/missing.
 
My 12 gauge just has the rubber washer inside is have to look if has the plastic ring elsewhere or not in the piston assembley, kinda rings a bell, it's been awhile since I've used the gun or had it apart, had two of them at one time kept the fancier one of the two and it always worked great and love the gun but was/is a PIA to clean. Got good at taking it down and putting it back together as I use to clean it after every outing, but then one day I handled my brothers benelli SBE and saw the grass on the other side and the inertia driven grass was greener than I had ever seen before LOL, bought a SBE 2 and never looked back at a gas piston again.

Ok sorry for getting carried away, but yeah if you haven't already downloaded the manual do it and look over every tiny detail, the one gun I got cheap because the rubber was gone and a thin piece of cork put in and it wouldn't work, the other one I got cheap too as the one small gas assembly part was in backwards, after the proper rubber ring in one and piston put together right in the other both worked great from light loads to heavy, even have a second 3" barrel for the one I still own and not problem with heavy loads either.

Actually the cap isn't a positive seal on the B2000, some caps had a hole in the center for a special swivel stud, the rubber ring isn't a seal, it is a buffer/spacer, but you are correct on the reading the manual with a fine tooth comb part, I had a printed out version that I think I almost wore out getting to know that gas piston by heart.
