Found 500 rounds of 100gr Amax for my 6.5CM Accuracy node is to load long. After my first hunt I pulled my charge handle back and out spills the brass with all the powder. Bullet lodged into the chamber! Ooooops!!!! Dislodged the jammed bullet. Cleaned the rifle. Crimped the remaining 19 rounds. Here's the results.

I can’t watch the video right now, but I would expect it to. You’re changing neck tension, most likely, which can affect pressure.

Way too many loose variables in that setting to call it a zero POI shift. Shooting off sticks while standing, shooting a large heat pad, field conditions, etc.
1- yes, crimping will increase your pressure of the round. 2- because crimping will also change the pressure, it will increase the speed of the round 3- if the speed increases, the POI can change.
In your testing, I seriously doubt you would notice a POI shift due to the loose testing conditions you are shooting them in. Try it in a precision rifle shooting prone, you may notice a POI shift.
