Home Forums Hunting & Shooting Gunsmithing need info on bolt disassembly for Cooper 21

Got a Cooper model 21 204 ruger , got misfires after some pierced primers, need info on how to disassemble bolt to clear and clean
thanks,

If it is like my model 38, you just take the screw out of the back and then unscrew the rear section from the body.

I had to polish some of the roughness off the internals to prevent misfires.

If the 21 is different, you might call Cooper. They are very helpful.
