I know that is what lever action rifles are called.
I was basing this off my own experience. I have a revolver that holds 8 rounds. I have a pistol that holds 8 rounds. If they are both loaded, I can simply pull the trigger 8 times to shoot eight rounds each. There is no separate “cocking or loading” action required (as there would be a lever rifle or single action revolver.)
I understand the technicality..but it walks like a duck and quacks like (a loud) duck.
It is no more a technicality than the difference between manual and automatic transmissions. It is what they are called.
Neither a revolver, nor a lever or bolt action rifle is a semiautomatic weapon.
