My 835 will hang up with H13s quite often. Used to hang up with steel shot as well. Talk about being dulled out in a pit blind!
The only thing I could do to make it work was clean the heck out of the chamber with a brush on a drill and some solvent very often and even then it will still hang up at times. The 835 extractor sucks compared to an 870. I had some Kent shells doing it in an 870 once as they were way too hot and you could beat the butt on the ground and the extractor still wouldn't let go.
This is a common problem with 835s. The best thing is to clean clean clean. If that doesn't work, do a light polish of the chamber.
