I named mine "FooManChew".HAHAHAHA... it took me a bit, but it is priceless... as per what to do. NEVER let go of the lever while loading. doing that is 100% safe every time.
I've got a B-3 but I don't know how dangerous... it really is. . I have heard all the stories and I am REAL careful of it. I have had mine for about 18 years and I still have all of my fingers.... BUT.... that doesn't mean that it is safe.Best Wishes - Tom
Or you could use it to beat in tent stakes and buy a great sub $100 air gun.
