I spent the morning sighting in the Williams sights on my used 835. I shot a box of AAs through it and 10 win hvs 3.5inchers. Twice, once with a HV and once with an AA the shell remained in the barrel. To remove the shell i had to put my thumb on the extractor and cycle the action. So my guess is the extractor spring needs to be replaced. Does this sound right? Anyone else had this issue? My gun is an old realtree mossy.
