I have to agree with Bogus on the severity of penalty for the SDQ .If it is heinous enough to be a potential safety of life issue then the shooter should be done,period ,regardless of how fantastic a shooter they are in all other respects and at all other times.
If it isn't ,then make it a no call.
To my mind , regardless of the shooting sport if you lose control of your firearm (170 loaded or not) or of your fire control awareness (trigger finger) ,then you should be done for that match .
On the subject at hand,TT is simple,it works and you don't have to explain it ad nauseam to everyone ALL THE TIME .This is a simple game with no cash purse. Lets just keep it safe and simple .
I don't see very many threads,posts or camp fire discussions clamoring to bring back the good old days of rank points in cowboy .
