Springfield and stuck cases....need help

[Lupinus]

So I went to the range today and had my springfield 84c to test it out.

First shot was fine, little off where I aimed but I had messed with the sights and it was in the first time in god knows how long it was fired, so being off was expected. First rounds no problem, cycle the bolt it extracts and tosses the case, little hard to cycle the bolt both on feeding and extracting I didn't have to force it or anything but it was definatly a little hard to do. So fire the second round and it heads on its way down range, pull the bolt back and what happens? Case stays in the chamber, hmm I say to myself. Pop the mag out put the bolt foreward and try agian, case comes out a tiny bit but agian fails to come out. So I growl a bit pull out the cleaning rods to push the lil sucker out and it takes some grunting to push out. So I try agian with three rounds, all three rounds same thing. Loads with a light bit of resistence but by no means does it need forcing, fires fine, and pull back the bolt and it is stuck needing to be pushed out with a little force with a cleaning rod.

Normally I would say extracter but if I try it with unfired rounds, just cycle the bolt minus actually firing them it extracts fine. The fired cases were a little scruffed and when examining the lead on the the ones I just cycled for comparison a distinct notch was made in the lead.

Any ideas what it might be or how to fix it?

Maybe just a little irregularity in the chamber a file or reamer or something like that could fix?

I'd try a different ammo before making irreversible modifications to the gun. Sounds like your bullets are too long. If contact with the rifling caused those notches and slight chambering resistance then that will also cause higher internal case pressure.

someone suggested that since this gun is made to fire shorts, longs, and LR's that potentially someone had been firing a lot of shorts and built up a ring. Will be getting solvent tomorrow to see if that helps, if not I will be shelling out 20 bucks for a chamber iron to manualy reshape it back proper. Since posting I have looked much closer and the top of the chamber has clear metal build up that I had overlooked, it isn't much which is why I probably overlooked it. Most definatly there if you look closly though.
