Artillery Rear Sight Offset???

Being a long range, high power shooter, let's talk ballistics for a minute. Can a 9mm go 800 meters? Sure. Can it do so accurately? Prolly not. I regularly shoot .308 and 30.06 at 600 yds, and a 6.5 X 284 at 1000yds. Planning reloads, you have to keep the bullet supersonic til it hits. Generally 1100fps. Muzzle velocity on the .308/ 30.06 is in the 2500-2700fps range to do this, with a 175-190 gr. bullet. The 142 gr. bullet leaves the 6.5/284 at 3200+. A 9mm 115-125 gr. muzzle velocity is 11-1250?

A bullet that slows to subsonic will start to tumble, and weave around. It is still dangerous, and will do harm. But I think the French Helmet thing was propaganda. Probably worked as the treaty made them stop making artilleries.
