Or just call it a bolt action, but it's definitely not a single shot. I had a single shot shotgun - you actually have to stop and reload it each time. Ditto with an old Mauser. I guess "repeater" is the correct term, but we used to reserve that for lever action rifles like the Winchester the Rifleman (Chuck Connors) had on TV.
I had a humorous experience once with a .25 caliber six-shot handgun a friend had modified to be fully automatic. I fired at a target and it just went "blip." I asked "What happened?" He replied "That was it, six shots." Yep, the magazine was empty. I had absolutely no sense of anything other than a single "blip." There was no blip-blip-blip AT ALL. I still can't quite believe it.
Orr says his 1.75 seconds between the first and second shots is enough time for the Carcano to be worked. He really needs to start paying me for all this free publicity.
