Russian Roulette

[BMAD 62]

You and four friends are playing Russian roulette, one bullet is in a chamber of a six chamber gun.  Each of you must take a shot from the gun.  The chamber will only be spun once, before anyone has taken a shot.  If you got to chose, which position, 1st, 2nd, 3rd, 4th, or 5th would best help your chances of survival?

Don't see how it matters, unless ...
 

Spoiler

You do more than "take a shot."

If you keep shooting until someone is killed, then just don't be the first to shoot.
Why? Because a bullet in either of chambers 1 and 6 will kill the first shooter.
The other four shooters have a 1/6 death probability.
