Also.... the guy who claims the shaft launched back at him also stated that the point of the shaft was the end coming back at him...
Not saying it didn't happen... but well.... I guess you should have played the lotto the same day...

Again, you can believe it or not. I just hope your last words are not; "aaaahh, uuggh, Glenn wasn't BSing me!" but then again that is why they created the Darwin awards...

PS As for the powerhead that eject the shell. A dive friend had a powerhead that the barrel fit into the base with tight fitting o-rings (not screwed on) the barrel had a cable around it's neck, the cable was attached to the base and when fired the barrel would disengage from the base cause by the blow-back. I thought the shell was ejected. This is a similar function to a lot of semi-auto hand guns.
IMO, these type of Slip-on Powerheads are safer because a lot of energy is released when the barrel comes off of the base. Check out "JimC" account of pool testing at
