There is no .338 Lapua Super Magnum. There is a .338 Lapua Magnum which is considered a member of "Super Magnum family".
.338 LM uses several different bullet types and drop will depend on bullet type and weight.
No such caliber. Sorry. If you man the Lapua .338 Magnum, drop will depend on the ballistic coefficient of the bullet being used, it speed, etc.
Depends on muzzle velocity, projectile weight and distance.
If zeroed at 100 yds, the bullet will drop ABOUT 275 inches below the line of sight at 1,000 yards. At that range, large number of variables including the muzzle velocity, air pressure, temperature and humidity.
A device that allows you to compensate for bullet drop
Impossible to answer without knowing Velocity and what your end state is.
Gravity.
Foor the .22 Winchester Magnum Rimfire, average max. effective range about 150 yards. Some of the newer ballistic tip ammo stretches that to about 200 yds. At extended ranges bullet drop becomes a significant problem in accuracy.
There is no one answer, since there is no one bullet. The drop of a bullet is a function of the speed- how long it took to get to 1000 yards. Some bullets will not TRAVEL 1000 yards. All other things being equal, the faster bullet will drop less.
yes
as far as it wants
Sorry, you need to specify WHICH .308 bullet and at what distance. As distance increases, the RATE of drop also increases.
The same as any metal.
