If I shoot into a hurricane, can the bullet come back and hit me? Are the winds strong enough to turn a bullet around and launch it back towards me? I'm (incorrectly) assuming there's no debris to bounce off of; I just want to know if the winds are strong enough. 
 A: A 150 mph (241 kph) hurricane is still only blowing at 250 feet per second (76.2 m/s).  A .270 caliber (6.8 mm) rifle has a muzzle velocity of about 3,100 feet per second (944.8 m/s) and a max range of about 2.72 miles (4.377416 km).  At 500 yards (457.2 m) the bullet is still moving at about 1,800 feet per second (548.64 m/s).  Assuming the bullet is fired directly into a head wind with the rifle barrel elevated +30 degrees (+30 degrees), the hurricane is too slow to have much impact on the bullet.  It'll be too far downrange for a 150 mph (241 kph) wind to reverse its course and bring it back to you.  What will happen is that the bullet impacts the earth a little less than 2.72 miles (4.377 km) downrange.
What happens in a 150 mph (67 m/s) crosswind?  Using my .270 Winchester, at a distance of 1000 yards (914 m) I get 44 yards (40.2 m) of lateral drift.  But my bullet is spin stabilized, so it acts like a gyroscope.  This causes it to rise or fall depending on wind direction relative to spin direction.  A rule of thumb puts the ratio between drift and rise or fall at 10:1 (for every 10 units of drift I get 1 unit of rise or fall).  That means my bullet either rises or drops 53.4" (135.6 cm).  Wind shear (vertical wind) is just a crosswind in a vertical plane.  Thus at 1000 yards (914 m) I'll rise or fall 44 yards (40.2 m) and drift laterally 53.4" (135.6 cm).
Thus, no matter what the wind direction is, at 1000 yards (914 m), hurricane force winds of 150 mph (67 m/s) don't even come close to reversing bullet direction.  The maximum ideal range for this projectile is only 2.72 miles (4377 meters) and at 1000 yards we've already consumed more than half the projectile's initial velocity.  At this turn rate, we run out of energy before we reverse the bullet's direction.
The bullet used in this example is a 130 grain (8.42 gram) Hornady boat tail soft point.
A: @Dave 's answer is reasonable. However, let us imagine for a moment that there is no gravity. Then a bullet flying directly into a headwind will eventually stop and then fly back with the wind. Therefore, if there is not just a headwind, but also a significant upward component of the wind,I don't see why the bullet cannot return back in the presence of gravity, as the upward component of the wind counteracts gravity.
Another situation when a bullet can return back in the wind is when it is fired in the direction that is close to vertical, so the horizontal component of the velocity of the bullet is comparable to the velocity of wind.  
A: I think it could be possible but extremely unlikely. Even if it did come back and hit you or someone else it would definitely be tumbling instead of acting like a normal bullet. If you look at how a bullet shoots under water you have to realize air is doing almost the same thing with way less resistance. The wind is always gonna change the course of the bullet nomatter what calibre. @dave @akhmeteli I think your both right in your own way. Unless you own a rail gun even just 1-5 km of wind will change the course. You also have to factor in if there's updraft, down draft or other equations. Technically nobody here is right until we put an RFID chip in a bullet and test it in different scenarios
A sniper rifle would be the most likely to make it through unless you're shooting from a distance of about 2 miles or 3.2 km aiming for the strongest part of the storm. It'd most likely go through with minimal change in direction.. however if you're using a small calibre. Pistol that'd be more than likely to turn into added flying debree or end up falling before getting even close to back to you.. try it in a wind tunnel that's circular and change the statistics every time, then do the math. I'd actually like to know lol. I know if you shoot a bullet straight up, it comes down in a completely different area, id like to know what happens in different scenarios. Example, with an updraft, would it continue following the course of the storm as it turns into a projectile, or is the wind too weak and will it just go through or fall to the ground..
P.s. ever wonder why a bunch of dead fish show up after big storms... Cause they gettin shot at from ppl who don't understand physics xD
