My Marlin 17 HMR malfunctions about one in 7 times with a failure to extract. It is bothersome to have to remove the magazine and reclose the bolt. On the second attempt it has extracted the empty case. I have cleaned the chamber some and have replaced the extractor ring. I am considering putting a bronze brush on a drill and polishing the area vigorously. Any ideas would be appreciated. The rifle is practically new. Maybe fired 100 times. Thanks for any help. Ben
I am using Hornady ammo. Chambers can cause problems because if they are not perfect the case expands out into imperfections and causes a bind. I will attempt to polish it out good and if that doesn't work I will check again with Marlin. Thanks. Ben
Ben, I have had the same problem with mine, even after replacing the extractor. Seems to be a problem mainly in cold weather. It has not happened with mine in warm weather if I keep the chamber clean using a good solvent and then cleaning the solvent residue out with alcohol or acetate. It's so darned accurate though, that I just accept this little problem as a maintenance issue.
The trouble with atheists is that they have no one to talk to when they are alone! Evolutionists and Creationists alike reject the truth.
I have fed a new round into the chamber and closed the bolt and then immediately open the bolt enough to visually see that extraction is occuring. It does until the round is fired. I believe that the case expands into chamber imperfections that causes more resistance than the extractors can overcome. It seems that after a small interval of cooling the case shrinks some to allow easy extraction. There is a lot of pressure on this very thin case because of it being a pretty hot little round. I will just polish the chamber good and unless necessary to reload quickly let it sit a short spell before attempting extraction. I can live with this small inconvience. Ozark
