shooting water?

how do you figure?

23G needle Inside Diameter: 0.318mm (0.0125 inches)
needle length: 38.1mm (1.5 inches)
Volume=pi*h*r^2
V=(3.14159265)*(0.0381m)*(0.000159)^2
V=0.00000000303 cubic meters
V=0.00303 ml

but i'll admit I use the air bubble too, but it's always been pretty much for peace of mind. can't go wrong with it; i heard it's taught to the nursing majors at my school to do it that way

edit: woops i believe i used a slightly different gauge at first, my first post has been edited to avoid confusion. however, the difference was minimal.

Haha. What a good example of overthinking things. Like the other guys pointed out, regular syringes (unlike slin pins) have what is called a "dead-space", and that is what wastes .1ml of oil.
