i own a handi rifle in 223 remington. it is the bull barrel model, if that matters. i am having trouble with it extracting shells. it is just luck of the draw if it will, or will not extract a fired shell casing. it always extracts factory unfired, or full length sized unfired ammo. but if i am using neck sized ammo, or touch one off, then there is no way of knowing if it will extract a spent shell or not. this has happend several times at the range. there, it is not such a big deal, because i always have a cleaning rod with me, just in case something happens. but if i am in the feild, and it has happened, it can be a long trek back to the truck just to get a spent shell out of the chamber. it has ended a couple of hunts. i tore it down yesterday, and thouroughly cleaned it out. i also took a honing stone, and broke ALL the edges everywhere except the contact point of the cartridge case. i also dug through my spring assortment, and installed longer and stiffer springs. i reinstalled everything, and shot it down with a coating of aresol "super lube". no luck. it does exactly the same thing. i also tried synthetic gun oiling of the parts, same thing. the extractor grabs onto the shell, but it will not pull it out of the chamber. does anybody have a trick up their sleve to cure this? is there a fix from the factory? its a hoot to hunt with, but i have had it with hiking back to the truck to remove a spent shell. so if i can not get this fixed, i will have to make this a range gun only. it seems to me that i saw a post somewhere about oil in the chamber causing trouble. i have tried this both ways. in fact, to extremes. from totally dry (brake cleaner soaked patches, then blown dry) to sloppy wet. once the shell is fired, it is still luck of the draw.
