Yes. About 50 years ago an old man brought such an 1897-01 Mannlicher carbine with him to our shooting range. He had a bag of loose old factory cartridges, probably 7.62 Mauser loads. Nobody cared then. He let me shoot a full 6 shot magazine at a 50 meter target. He watched me trying to shoot the thing, quite amused. At first I pulled the little carbine back into my shoulder as i would hold any other rifle or shotgun. Nothing happened. He then told me not to pull back on the foreend. I gripped the wood foreend with my hand, careful to keep it forward. Bang! but no ejection or reloading. Only then the old man instructed me to hold the foreend with my fingertips only. The next five rounds fired and worked perfectly. It's a long time ago now and I don't know what happened to the carbine.
These Mannlicher Selbstladekarabiner may be well made and nice looking. But a gun that does not work properly in a hurry is pretty useless imho.
