7.62, 7.63, 7.65 mm???

Just to show how arbitrary the numbers are, using 25.4mm = 1in the numbers work out :

7.62mm = 0.3000in
7.63mm = 0.3004in
7.65mm = 0.3018in
9mm = 0.3543in

Personally, I think that the manufactures just picked a number that was close to the bullet diameter and called it good?

Tac,

Sad to say that the English Pit Rifle Range is closed until further notice. I guess the area is just too developed now to have a rifle range there. Safety concerns were given as the reason. To tell the truth, I am surprised that it lasted as long as it did.
