What a waste of ammo............and Dr. Pepper..................

I thought “muzzle blast” was the flash and fire that issues from the muzzle once the bullet leaves the barrel, allowing flames and smoke to blast out behind it.

BTW, the video at the site is more than 16 minutes long.

The story I heard was that John Moses Browning observed grass being pushed down from the muzzle blast of a rifle and was inspired to harness that power to create a semi-auto rifle.

Have you ever wondered how much power, how much energy, comes from the muzzle break of a rifle?

No, but I might wonder how much power comes from the muzzle BRAKE of a rifle. A broken muzzle wouldn't work too well.

I own a .50 cal air rifle.
A scuba tank fills the chamber proving 4 shots of .495 round ball.

There’s usually more energy in the gas exiting the barrel than there is in the bullet. Muzzle blast almost always is responsible for more of the recoil than the bullet is. One reason why suppressors also are effective muzzle brakes.
