So I go to unload my 35 rem yesterday at dark for the last time and it hangs in the open position throwing the chambered shell out but locked up now. Lever won't close.I did remove the tube spring and get it unloaded but after all that the slide plate where you load is flopping loosely and I did get it shut but it'll hang immediately if you open the breech again. This is an older pre safety and has been awesome all year. Only upside is that it waited until the end of season. Any ideas? Thanks
