I just got a .410 shotgun from my grandfather, it is unlike any gun I have ever seen. The gun is a single shot, but the interesting thing about it is how it is loaded. I will try my best to explain. In order to load the gun I have to pull back on a trigger like mechanisim directly above the trigger. After I pull back on this trigger the entire barrel rolls up, and then I put one shell in and roll the barrel back down while holding back on this trigger. Now the gun is loaded and ready to fire. If anyone has seen a gun like this please email me information. My address is [email protected].
