Geo. with all do respect...thats complete hogwash about the shells being thrown across my face and field of vision...Ive NEVER seen the shell eject out of one of my guns...ever. I seriously doubt anyone else has either. Even if I have seen the shell subconsciously...it happened so fast that I never truly noticed. The ONLY issue Ive ever had was with a Remmy 1100 that used to spit powder out of the ejection port or gas port (it came from somewhere?) and it would sometimes get into my eye. Thats it. That kind of rubbish is a pure eye roller, especially when your including automatic pistol shooting or shooting an automatic rifle. Never even see the case ejecting. If you do...youre doing something wrong...like not focusing on the target.
I've never seen the empty shell when shooting a pump or semi-auto either. But I bought an unusual pistol a couple months ago. It is a Wamo Targetmaster single shot .22 rimfire that was built by the Wham-o Toy Co. Only a few thousand were built, and Wham-o will deny ever building a cartridge firing gun. But there are ads from the early 1950's clearly depicting this gun along with Hula-Hoops, Frisbee's, Sling-shots, etc. It is a delayed blow-back single shot design that fires with an unlocked bolt. Upon firing, I never see the spent shell casing which ejects straight up across my line of sight, but the empty case often lands directly on top of my head.
