cos it's funny to call you at 2am and listen to you 'talk dirty' to yer missus.. hope she gets turned on by it..

That dirty talk is directed at you..

"tell the bleepin' bleepity bleep so stop bleepin' calling at 2 o'clock in the bleepin morning. One more bleepin time and I'll cut his bleepin' bollocks off"

Bullets have to be round. They rotate in the barrell. Helps them travel further. Then there's the issue of drag v air resistance associated with objects with sharp corners travelling through the air etc.

See post #4, those 'trounds' are 'trilingular' (Spike Milligan speak for triangular) in cross section!!

There was a square 'round' for a rifle developed in the 19th century.
It was designed for use on heathens who didn't deserve to die from white mans bullets.

Dunno if it helps them travel further, but they rotate to help them stay accurate. Dunno the physics behind it, but a guess would be that if the bullet is imperfect, then if its rotating then the imperfections would then cause equal drag in all directions. Also, it could have something to do with it causing a gyroscopic effect, similar to what helps us buggers stay upright on two wheels.

The rotation is caused by scoring on the inside of the bore, called rifling (hence the term "rifle").

Anyone care to confirm/deny?

When cannons first shot lead balls the only thing that could be predicted about their accuracy to the target was that the balls would move in a forward direction.

Later on some genius decided that by elongating the balls they would cut through the air a bit better, they did but accuracy wasn't that greatly improved.

Until another genius figured out that spinning the projectile keeps it going a lot straighter.

The scoring of barrels was first done to the barrels of very early cannons.

This caused the projectiles to spin as they came out and gave them a greater firing range and greater accuracy - by spinning at a very high speed they sort of stay on course for a longer duration. Gyroscopic forces or something.......

Sniper -did your sniper rifles have those spiral indentations inside the barrel??

In the Navy (reserve) we never referred to them as rounds, to us a round was a round of drinks

, a bullet was just that a bullet.

Sniper, this guy is seriously boring - don't get sucked into his vortex.
Oh no...it's too late...quick...grab my hand.......................!

And then there is the issue of cut vs swaged vs forged rifling, of course then there is the argument of micro-groove rifling vs just 5 lands and grooves.....oh and did you know that in WW2 there were 303s with just two grooves???? the ball is in you court idb to add to this fascinating subject....

And then there's the Beach Boys...

I'm gettin' bugged driving up and down the same old strip
I gotta finda new place where the kids are hip

My buddies and me are getting real well known
Yeah, the bad guys know us and they leave us alone
