.22 LR (long rifle/long range)

[Dipstick]

I haven't bought any for years, but the flap on a box of .22 LR used to say "caution, range one mile".

Yes, the projectile can travel up to a mile, weather it hits what you're aiming at is a totally different subject! And I'll bet you 100 out of 100 that you'll miss every time!

At that range the curvature of the earth starts to become your friend.
