full auto bullet spacing

I brought this up a few years ago and we had an interesting thread going so I thot I would bring it up again. In a standard m-16, in full auto fire, how far apart do you think the bullets would be in flight? I have no clue but lets see what the experts think.

I suck at math but figuring a cycle rate of 700 rounds a minute gives you 11.66 rounds per second. At 3000 feet per second there should be a round every 257 feet (3000 feet of flight divided by 11.66 rounds during the same second of time).

I'm probably wrong about the cycle rate.

This is basic math, there's nothing really to be an expert about.

2@low8 is spot on. Same math with Wiki's numbers (825RPM/3110FPS) is 225 feet between bullets. Just pick your RPM and velocity and do the math.

How about adding another aspect to the math?

How fast would an object (let's say a jet aircraft) have to be going to have a chance to pass between the bullets in the stream at a 90 degree angle to the stream, without getting hit, assuming the most favorable start as possible (nose of the jet enters the bullet stream just after one bullet passes by)? I think you'll need to choose a specific aircraft, to get the length of the object that is passing through the stream...

A 100 foot long aircraft would have to be traveling at 1100 fps to go between the bullets. About 750 MPH.

bullet gap is .08 seconds. Object needs to travel 100 feet in .08 seconds or 1100 FPS or 750 MPH.
