If you went into a Blood Vessle or Vein?

If you went into a blood vessle or vein when you pulled the needle out wouldn't you get a nice squirt of blood...?

not always. if you're shooting in the glutes lets say with an 1 1/2 pin it would be difficult for the blood to find its way thru the pin entry and squirt out.

ive hit a couple good gushers in my shoulders and quads.
