I had a Chinese made one which would sometimes totally lock the bolt with Chinese ammo. I would have to take a block of wood and beat it open.
I gave it to a guy and he never had that problem. It must have been the ammo as he used a commercial soft point.

Went out of print in 1933 or so, but still...
That is the well documented "sticky bolt syndrome."
Fairly simple to eliminate.
