The old joke about the computer IT help desk is that the standard phone greeting is "Thank you for calling IT support. Please hang up and reboot."
In a like manner, most of the problems you mention will be caused by dirt/ lube problems, or broken parts. Your rifle should be a High Standard A1041, and SHOULD be for .22L or LR, and .22 Hi Speed Shorts.
Would begin by taking down the rifle, scrub the bolt, extractors, firing pin channel and the chamber. While the action is out of the stock and the rifle is UNLOADED, cycle the action by hand and see if parts like the cartridge elevator are working, etc.
.22 RF ammo tends to be really dirty, and frequently the buildup of carbon, wax lube from bullets, leftover peanut butter from your sandwich, etc gums up the works. Before a trip to the smith, hang up and reboot - sorry- hang up, clean it.
