-Yep the acceleration time is so short it doesn’t have much bearing.
-Don’t forget the explosive gasses that eject the bullet increase the accelerating mass.
-And the fact that the gun Jamie and Adam held experienced the full opposite forces that the accelerating bullet caused, whereas the bullet shot to the gun only imparted a fraction since it broke down and continued to fly everywhere in still high speed.

I agree with that the holder of the gun will grip it tighter than usual, you just can’t help it.

Hope I made sense to yall. :)

the 20 mph was a simulation with a smaller bus almost toy size. everythign fit to the scale factor.

I read these comments. I see a flaw in the handgun rig that no one mentioned. Here is the problem It is all about weight. You added weight to the pistol. More weight = less recoil. The question of acceleration is a small one. The bullet still gets full acceleration at the time it leaves the barrel. Around 900 feet per second. It will travel the barrel length in less than 1/1000th of a second.

“Sqeezer says:
The tests that use a second barrel or a second handle have a severe flaw.”
Sqeezer is exactly right: If the force when fired was the same as at impact, the bullet should shatter before it leaves the barrel!
I’m afraid one of the Mythbusters is going to have to take the bullet!

I doubt it would happen, the problem is the bullet is facing much more resistance underwater and it would no doubt mushroom, meaning flatten out due to resistance, before it could even make it to the chain.

It is easy to hold a gun tight enough to not get it knockled out of your hand if you know it is comming. Even if it is a randome time they are still expecting a kick out of the normal range so it is not a good test. I have actually seen a gun shot out of a persons hand by a sniper during a police standoff and he did not get any injury. It worked because he was not expecting it.

try diffrent tires on jumping bus :)
it maye work better

Yeah and in the making of part of the film, they used a huge ramp (which was meracuously edited out) and the bus was travelling between 70 & 80 MPH

Their two guns at 90 degrees test rig for the first item was flawed. A bullet hitting a gun slows down in a shorter distance and exerts greater force than a bullet accelerating along a barrel over a greater distance.

I agree with the Squeezer comment as well, I thought that at the time that this does not correspond to the same event exactly. The car crash analogy is perfect in showing why.

I also thought the baseball bat hit on a paddle on the pistol suffers from incorrect scaling factor with slower deceleration but more momentum than a fragile bullet might impart, so was also irrelevant.
