Has anybody actually checked the distance that the bullets are seperated by at various differances? The post gives a mathematical formula for disance at 120 meteres. The way I understand it is a Double sort of flips the bullets out during it's recoil. Up and to the left for the left barrel and up and to the right for the right. Somewhere in that arc the bullet leaves the barrel.

If this is true than the distance the bullets are actually apart when they each leave the barrel will be greater than the distance that the barrels are apart.

Is it a direct correlation between crossing at 60 meteres and the 3/4 inches at 120 meters? What is the distance apart the bullets would be a 50 meters if they cross at 100? At 200?

Who the Hell knows? Not me, that's for sure.
