I did all that you recommended, but it is still doing the same thing.
When the bolt stops, if I gently touch the tip of the extractor/bolt then it will let the bolt slide all the way back to the bolt-stop. Something is keeping it from aligning as it is supposed to. I've cleaned the gun inside and out, I put a little grease on the lugs, the tracks, and all of that. I put a little bit of oil on the bolt's moving parts.
When the stock is off, I put one hand on the front slide when I pull back the bolt, it tends to work. Not always, but usually. If I turn it all upside down and pull back, the bolt hangs up. If the rifle is assembled, the only way it works is if I touch the bolt/extractor tip when it gets to the Hangup point.
The extractor seems to stay snug, it seems like it's positioned to be holding brass, even if there's no brass to hold. When I manually load a Round, I have to pull the brass out b hand, because it will still be gripping it. Does that explanation make sense?
The extractor spring seems strong.
I'm going to continue searching and I'm going to take a closer look at it tonight. Maybe something is bent just a little that it's getting in the way of some part in the bolt or maybe keeping the bolt from rotating just a hair?
I don't know.....
I like fixing my own problems, but this is stumping me. J need to find a reputable gun smith in my area.
