Everything looks right

[Kurt]

I can slow and freeze the frames more with the software I have. When the bullet is about 1" in front of the smoke the wad is just raising straight up and the patch is peeling back the outer layer from the front of the bullet. And guessing now; about 30" the patch is spinning the outer layer off, not shredding like I find my remnants when I shoot in the shed where I find all of my patch.
This makes me think that he might have used a harder paper like vellum or thick paper. But regardless the bullet is clean at about a barrel length down range.
