Proper grounding of metal junction box

I believe the proper way to ground a metal junction box is to pigtail it from a grounding screw on the box to a wire nut with the other incoming ground wires. I have seen where instead of pigtailing from the ground screw, one of the ground wires from an incoming wire is wrapped around the screw and then it extends out to be wire nutted with any other incoming ground wires. Is this allowed/ up to code? The length of the wire extending off from the screw is the proper working length required by code. Thank you for your help.

Either way is fine.
I usually wrap one of the incoming wires and extend it out. One less wire under the wire nut that way and one less in the bundle to fold back.

I wire the same way Petey does. One incoming wire under the screw then extend it to the wirenut.

Most of the folks I know in the business do it this way as well, FWIW.
