Why don't my bullets move right away?

[gusty rain]

logs

as you can see the position on the bullet stays the same until 2231, 516ms after it's physics loop starts running

but the variables used to calculate the position are fine before that

im guessing im just using physics wrong, but i keep ending up at this terrible page https://docs.godotengine.org/en/stable/tutorials/physics/rigid_body.html#doc-rigid-body

how am i supposed to move a rigidbody normally
