Everything looks right - Kurt - 12-04-2013
I look at this quite often to see what is going on as the bullet clears the muzzle. I don't see and gas ahead of the bullet when it first appears but as it is just about clear I see a cloud showing up. If your reflexes are good and stop the frame at about 00:58 I can see just a little more smoke at the top of the bullet before it clears the muzzle. This makes me wonder what caused this? blow by? and what effect did this to the bullet in flight?

it looks like the patch is coming apart to start and the gas starts as the bullet clears, could be the crown making it appear the gas passes the bullet.and recoil makes it higher than the bottom,
I have a night picture showing a 12 ft.muzzle blast , but it is broken in the middle by recoil,and is on two planes

Did you see the felt wad dropping off the bullet? I think the gas cloud is just blowby, occurying more or less naturally.
One thing I find interesting is how the smoke was trying to curl back over the muzzle in a mushroom fashion at the start, and then you see the bullet come out of the cloud and the paper blowing off. Which sort of make me wonder more about a theory I have on patching bullets to big in diameter with thicker paper, is if the bullet is trying to expand and decompress as it comes clear of the crown, and possibly affecting the spin and trajectory.

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.
