I too am curious as to how guys cheat.
They have mentioned shooting more shots than the string-of-fire allows...,
Loading two projectiles on your next shot when you realize your last shot on a paper target was a clear miss...,
There's a buddy in the spectator area with bino's who signals to his friend on the firing line where each shot has landed, when normally nobody can tell until the targets are scored, so the guy with the buddy can adjust his point-of-aim....
A shooter has a ragged hole in the paper target, so knows if a shot missed the judges would say that miss went where the others went..., and then that shooter put his last round into the paper target of the guy next door, who is shooting well too... or was until the judges spot he has one too many holes....
A guy is doing very poorly so deliberately misses his target, as it won't matter to his standing but puts that last ball or two into a guy's target who is doing well, to disqualify him...
Also, when you're talking paper targets, whether or not the hit "cut" the ring means a full point difference in the score, and that sometimes means placing well or not, in the match....
Wearing one's sash high up on the belly, and looping the sash through the sheath knife to secure it to the body, BUT the butt of the knife conveniently hangs right were it needs to be to rest the shooter's elbow on the knife and thus... standing and shooting "offhand" aka "standing/unsupported" is now "supported"....
Installing a tang bolt with a really pronounced head, so that the groove for the screwdriver works quite well as a rear sight in a smoothbore match were rear sights are not allowed...,
