I bought a Stoeger 2000 12 gauge semi-auto a couple of weeks ago. I took it to the clay sports range a couple of times to get used to it and break it in. I made the mistake of not stripping it down and cleaning and lubing all of it before the first time. I did lube the parts I had to assemble the first time I put it together. The first time we went out it kept misfiring occasionally. The primer barely had a strike on it. Also, it was really inconsistent about loading another shell. This was very frustrating to say the least. I stripped it like instructed in the manual and cleaned and lubed everything good and reassembled it. The next time I took it out it misfired on the very first shot again. You gotta be kidding me. I ejected all the shells and fired it several times unloaded. It never misfired again. It still had problems cycling shells. It always ejects the shell in the chamber but it ocassionally doesn't load the next shell. It's as if the gun is empty. I can push the next shell back into the magazine and release it, and then hit the carrier release and the shell will make the "sha" sound and load when I pull the bolt back. I was using 2 3/4" shells, but used 3" shells one time and it cycled perfectly. Has anybody else had problems with this gun? Is this something that will get better the more rounds I fire? Thanks.
