Norinco 22 cal made in china distributed by interarms alex va model 22 atd and need the load tube through the stock?

you can load it through the hole in the side of the stock or in the back if the tube is removed. I unload mine by removing the tube and dumping the cartridges in my hand, replace the tube then eject (usually two rounds) out of the action until magazine is empty. ALWAYS CHECK!!!!!!!!
