So, if you were at the center of the Earth, and were shooting from the hip, (say a .45 Detonics pistol) where would the bullet end up?
And what gun laws would you be subject to? Jerry Johnson >>> [EMAIL PROTECTED] 09/10/02 01:57PM >>> I'm so dizzy my head is spinning... I guess I just shoot from the hip (I've read at least three chapters from A Brief History of Time and I wanted to impress you). <g> ----- Original Message ----- From: "Robert Everland" <[EMAIL PROTECTED]> To: "CF-Community" <[EMAIL PROTECTED]> Sent: Tuesday, September 10, 2002 1:42 PM Subject: RE: Hole in the Earth? > HAHAH you just answered that?
