I've seen very few O's center punched, but lots of attempts. Many were in the O but not centered, guessing most within were shot at very close range based upon entry/exit hole.
Those are very good results, especially if they follow the rules of the game. Which are as follows:
Drink a half pint of Jack Daniel's, or 12 tall boy beers of choice in 30 minutes. Four participants. No participant is allowed to urinate until all have shot their target.
Take one high horsepower 4wd pickup that will hit 120 mph.
Intoxicated driver will try to miss the sign no greater than 6" at 120mph.
Shooter must be standing in pickup bed, holding on to his ass and pistol.
And shoot the sign as they go past at 120.
The two non shooting participants may sit in the bed of the truck and offer encouragement and may hold the shooters beer/jack d while he shoots.
Colt Ford on stereo, really loud.. Buck Cherry, Bloodhound Gang, Mickey Avalon...
4 way stop is ideal, 4 chances, one per participant.
To add challenge, one naked sister in back with shooter....... ahhhhhh "bj"....
Anything less is cheating and unfair to the stop sign.
Least, that's what R said was the rules up in them hills.
