Hahaha, Headshot is a wanker!
OK, the ammo I've used and continue to use is 50 to 60 years old! Yep you heard right folks.
FYI, One of the rifles I've used is 117 yrs old.
The only negative thing I've had is misfires. SOP = upon hearing "click" hold weapon in the aim for 30sec then re-cock and fire again if round does not fire, hold in the aim for a further 30sec then unload and dispose of round safely, i.e. bury it etc...
Ammo isn't going to explode just because it's old.
Now let me add to this, the ammo I've used and am talking about was in good condition, no corrosion etc... present. I will not shoot ammo that looks dodgy, capice?
So, clean to the eye ammo, WWII vintage or newer is good to go IMO, I use it all the time and have only ever had failure to fire problems.
:2c:
But what the fuck would I know, I'm not a sniper. ;)
