Get a kinetic bullet puller. You'll use it. I've just about worn mine out.
It sounds like you jammed a bullet into the rifling and it got a grip on the bullet. When you tried to extract it, it held it and withdrew it from the neck of the case. Way too long.
There is no one OAL for any cartridge. It depends on the bullet shape and the magazine length.
