The Chinese actually make a very good clone of the old Crosman 180 CO2 pellet rifle. Since Crosman doesn’t make that model any more, I’m sort of glad that the Chinese penchant for copying successful designs is keeping it alive, sort of. Real metal and wood construction, too. Google “QB78”; the rifles have developed quite a following.
Someone mentioned upthread that loading pellets in a Crosman 760 is easy and I concur from having had one as a kid. I haven't tried any pellets in my Chinese Daisy 880 yet but I can tell by the shape and size of the bolt area that it is not going to be easy.
