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

Have you tried to contact the factory?

I contacted the factory and they sent a new extractor but that didn't solve the problem

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

I would do what you are doing first. Little chambers don't need much fouling to cause this IMO.

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.

Have you tried to pop the spent case out by hand to see if is stuck or if the exsractor just did not grab it.

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
