I've got a 91/30 M-N that has a slight (user related) problem. While on a weapons stack, it got knocked over onto the bolt handle while the safety was on, the the bolt opened partially. Now it fires, but I have much difficulty operating the action; it doesn't rotate freely. It gets stuck about halfway up, but if I slap it hard it'll free the bolt. I disassembled it (the bolt) and checked it over for bent, broken, or otherwise unserviceable parts, but everything looks absolutely fine. I also looked over the chamber and receiver; same thing, fine. I've ceased to use this weapon for now but the question I pose is: Has anyone had a similar experience, and if so, need I get my weapon serviced? Or is it safe to use, albeit inconveniently? Thanks for your time.
