does IR produce a bullet spin

[Ken B]

A "backdoor change" would have you "inverting" your hand/wrist/forearm through release, and releasing the ball with the thumb "pushing" the ball toward the catcher.........Out the "back of your hand" so to speak............[/QUOTE]

Like a flip change without the flip?

A flip change imparts "backspin" on the ball...........Like some slow pitch pitchers pitch............

You flip the ball into backspin with your fingers going from infront to on top the ball and use a very low follow through..............

A very dangerous pitch........Because backspin causes the ball to "float" longer..........

If the index finger writes a clockwise circle in the air.........It looks like this from the catchers view...........

Bullet spin........

This is the image I was looking for. Some people mistake this rotation for bullet spin.

You are correct, this isn't bullet spin. This is a 1/7 rotation. This rotation would cause the ball to drop, but also dive inward on a RH batter. This is usually achieved by a slight wrist flip in toward the right thigh at release. I say slight because the predominant spin is a true fastball or drop ball spin.
