If you are telling me that the empty hull jumps out of the grasp of the extractor before it is fully rearward and ready to be ejected then what you have is one of Ruger's ejector springs that hold too much tension. I have seen this fixed with the simple replacement of the spring. It is inside the bolt behind the ejector button on the bolt face. Usually when this is the problem the rifle will extract and eject loaded rounds well but when the case is empty and light it will push off the bolt/extractor prematurely before it is in correct position to leave through the loading port.
There is no ejector spring/plunger on this model. Just a claw. The bolt face is smooth...mauser style, not plunger style. The ejector on this Hawkeye is a fixed bar located way back inside the receiver. When the cartridge hits this bar, the round is ejected. Unfortunately, when the claw is extracting the round, the round just falls out of it and leaves the round partially extracted.
Just received an e-mail back from Ruger on this. They are saying that the claw is not holding the round firmly against the bolt face. And yes...this is exactly what it is doing. If I take the bolt out of the rifle, and I drop a round behind the claw, it just wobbles around behind it and falls out easily. There is no resistance to "hold" the round behind the claw. I'm thinking about just disassembling the bolt and bending the claw myself.
On a good note: Ruger fixed both of my new revolvers, and will be sending them back next week. No charge for shipping or repairs. yea !
