I just picked up a ithaca 300 semi 12ga. I'm planning on heading out for some trap shooting tomorrow. Anyways i went to load it, got it loaded, then went to unload it. Heres the problem when i pull the slide back, it will eject the round in the chamber, but will not cycle the next shell up and out. Is there something wrong? or will it only cycle when im actually firing. I can get it unloaded but i expected it to unload like that........First time with a shotgun. also what do these usually go for price wish, i would say the gun is in good-very good condition. any help would be great, thanks
