Auto left mouse clicking software?

Hallo everybody,so in this thread i wanted to ask if there is any software (maybe just a script) that allows me to click very fast while i hold down the left mouse button(without having to tap it).Something like turbo button that some gamepads have.thanx in advance!(it's gonna be used for shooting fast weapons with autoloader ex.shotguns,snipers etc)

SendMode Play
~*LButton::
loop
{
GetKeyState, LButtonState, LButton, P
GetKeyState, CapsState, CapsLock, T
if (LButtonState = "U") || (CapsState = "U")
{
break
}
else
{
send {click down}
sleep, 10
send {click up}
sleep, 30
}
}
Return


so here is the script it wasn't so difficult to figure out though.

There's hundreds of auto clickers out there. Try finding one that will let you use your mouse to turn it on or something

AutoIt:
While 1
MouseClick("LEFT")
WEnd
