In Fallout many things could happen, people may get stuck in the back of a Robot factory fending off death machines with a gold pistol (http://www.falloutwiki.com/Maria). There have been quite the few times when one bullet made a big difference in a fight (which I cant really recal cause I have not played new vegas for a while).

But I gotta ask what was the luckiest shot you ever had in Fallout (Fo3 included), what kind of ammo did you use?

This aint just to brag about a lucky moment you had but to also help inform other peeps to what ammo can be usefull in some situations.

Oh and watch out some people have a itchy trigger finger and snipers stand ready .

Well,I was once near quarry in FoNV and I just started spinning see how fast I could turn with sensitivity all the way up,I happened to have an AMR equipped at the tine,and randomly fired a shot while spinning at Mach 56 and got a sneak attack critical on a death claw.
