45ACP with 135-grain Lehigh Defense Xtreme Penetrator Bullets, 7.8 grains of Winchester 231, and Remington 2 1/2 primers In testing the rounds with one of my older sons, we caught a muzzle flash on video that produced interesting results we had never seen. I've attached the video in slow motion and two stills from that video. In the first still, you can see the muzzle flash exiting the barrel, quite a big one, and then in the next still, you can see the flash turned into a tube. The tube displays three bright yellow flames that look to be rotating.
It seems to me that the tube same is created as the bullet moves through the initial mizzle flash. The bullet geometry, the nose design in particular, and the spin of the bullet moving through the flash cause a void in the center of the flash, and the nose design of the bullet causes the flash to spin. That is only my guess.

Now that is seriously cool! I handload for my 45 but have stuck to big, heavy bullets. I reload LeHigh copper solids in my Lee Enfields to good effect.
