I have an STG-58 FAL built on an Entreprise Arms receiver. I've only shot it twice, both times with Bernaul .308 Win steel cased ammo.
Before anyone starts in about the evils of Wolf/Bernaul ammo, just say that I knew about it and took the risk. I got burned.
Anyways, the first trip to the range worked great. However, it was in the fall. Now that summer is almost here in the high desert, I went shooting again. I did not scrub out the chamber of my rifle from the first trip.
Last Saturday, I loaded up a magazine with the same ammo, and on the first shot, the case stuck in the chamber, the extractor ripped off a piece of the rim, and the primer blew our of the case. I think that my gas port may have been set too high for the temperature, causing too much force in the extraction cycle. I tried to tap the case out with a rod, but I just poked out the Berdarn priming holes. The case is stuck in there TIGHT.
I then tried to soak the case in KROIL, a penetrating oil from the magazine well end. No effect. The oil DID penetrate, I found a bunch of it had penetrated through the barrel threads to the outside of the barrel!
I've ordered a broken case extractor from Midway, but this is stuck TIGHT. Do broken case extractors have the kind of leverage needed to unstick something of this magnitude? I realize that the case head must be off before I can use the case extractor. My current plan is to cold chisel the case head off and try the broken case extractor. The case is sticking 1/8 inch out of the chamber.
Another option is try KROIL more forcefully. I'm thinking of using a rubber stopper to stop up the hole in the bottom of the case and fill the chamber with KROIL over the top of the case, so that it will penetrate down between the case and the chamber.
Will this work?
HELP!
