No.
If you get into the same inertial frame of reference as the bullet then it will look like just a bullet.
Your time will dilate only slightly with respect to where you were when you fired the bullet.
(after a week of travel you might have lost a few milliseconds of time.)

Well, that pretty much depends on how fast you are traveling. If you are traveling under the speed of light 300.000km/s it's explained with classical physics and the Galilean transformations, and if you are faster than the speed of light it's relativistic physics and it's solved with the Lorenz transformations, which are fairly different than Galileo's ones.

But, since max bullet speed is approximately 1.5 km/s, you would need a lot less than speed of light to be faster than it, so we'll consider the question in the classical mechanics.

Lets say the bullet's speed is Vb, and your speed is Va.
If you and the bullet travel in the same direction, but you are faster (Va > Vb), the speed you'll experience referencing to the bullet will be V = Va - Vb. So the actual speed the bullet will have compared to you will be a lot less than it's acctual speed.
If you have the same speed (Va=Vb), than the speed according to you will be V=Va-Vb, since Va=Vb => V=0
So if you travel with the same speed it will appear to you only that the bullet isn't moving, only your environment.
And if you and the bullet move in the opposite directions, and you have the same speeds, it will seem to you that the bullet is moving twice as faster, since if the direction is the opposite. In this case the equation will is V=Va+Vb.

It's the same situation if you're driving in a car on the highway. The cars driving in the opposite direction seem to be moving faster, and the cars that move in the same direction with you seem to be slower.

But this has no effect on time. When it comes to speeds close to the speed of light, there is a thing called time dilatation, and at this point relativity of time becomes debatable.

Yes u can see the bullet moving in slow motion and if u are lucky enough u can catch the bullet .Catching bullet is nothing new,there were stories from world war ll where fighter plane pilots caught speeding down bullets

AAAARRRRRRRRGGGGGG!!!!! What must they be teaching in school?

Motion you see is relative to you.

If the bullet is traveling 1100 feet per second, and you're traveling at 1110 feet per second in the same direction, to you it will be moving backwards at 10 feet per second.

If you're traveling at 1090 feet per second in the same direction, it will look like the bullet is meandering past you at 10 feet per second.

If you are traveling at the same speed of the bullet, it will appear stationary to you.

If you are traveling in the direction from which the bullet is coming at 1100 feet per second, if the bullet doesn't hit you, it'll pass you at 2200 feet per second.

But, relative to somebody watching on the ground, the bullet is traveling at 1100 feet per second, and you at some other speed, or in some other direction.

If a plane shoots a projectile, bullet or missile, the speed is additive. That means that if the plane is traveling 600 mph and the projectile is launched/fired at 500 mph, it closes on the target at 1100 mph. If that were not so, planes would shoot themselves down by flying into their own bullets/missiles. I believe some planes actually flew into bullets they fired because they lost momentum so rapidly after leaving the platform. However the high speeds necessary for that to happen are hardly practical in a dog-fight because of the G-forces they would cause during the maneuvers executed in aerial combat..

Also, if speed weren't additive, no matter how hard a pitcher threw a ball, it would simply drop to the ground when he released it.

It's like driving down the freeway at 50 mph. If you hit a wall, you hit it at 50 mph because the wall isn't moving. But if a car coming towards you at 50 mph, you hit at 100 mph... just as if you hit the wall at 100 mph.

Missiles are used at longer ranges because they don't succumb to gravity as rapidly as a bullet. The power used to fire a bullet stops immediately when the bullet leaves the weapon that fires it. A missile has power as long as it has fuel. Besides, newer missiles can now track a target.

You do not stop time. You don't even slow it down. The seconds tick off at the same speed whether the bullet is passing you at 1100 feet per second or 10 feet per second, or if you are passing it at 10 feet per second.

You could fly along side the bullet and see it clearly. It is like how you can see other cars around you on the road as if they were barely moving even though you and them are all driving at high speed. It is just that you are all driving at the same speed and in the same direction. But doing this does NOT stop time.

good question!
look.if you have the same speed as the bullet you will think that the bullet is not moving.

if you have a similar speed you will see the bullet in slow motion.

Yes you can see the bullet slow down and eventually fall to Earth. No that means time is relative.

It's not in "slow motion", if it hits something, that something will be damaged at normal speed it just appears to be traveling slower, that's not slow motion.

If a boat is going 35 mph and you are going 37 mph, it appears quite slow, but the people on it appear totally normal, it's not "slow motion"

You can do it with an airplane. That is why they switched to missiles when jets came out in the Air Force.

time does not stop, only you apearent perception of time changes. and by the way you can't fire a gun in space there is no air.
