No, if you neck down a case to accept a new caliber bullet, or "wildcat" a round, you must re-barrel the firearm to the new caliber and have a new chamber made to ensure proper head spacing. If you neck a casing down and use the same barrel and chamber you are going to have hot pressurized gas escaping around the case and the bullet. This can be absolutely disastrous if not deadly!
The First bullet train was made in 1930
With the serial number that you supplied,your Savage model 99 rifle was made in the year 1940.
None. A bullet is a bullet, regardless of what material it's made from.
To the best of my knowledge, no manufacturer has even made a .38 Special rifle, so no. .38 Special can be used in .357 Magnum revolvers, but that's because revolvers don't have a headspaced chamber - this cannot be done in firearms which have a headspaced chamber (as rifles typically do).
The first bullet was made at 1883. It was a Smith and Wesson .22 caliber rimfire cartridge.
Samuel Colt made the first percussion cap revolver in 1836- but it was not the first. Elisha Collier made a revolving flintlock pistol in 1818- but it was not the first. James Puckle patented a revolving cannon in 1718.
the simplest engine that is made up of a burning chamber and a nozzle is a rocket.
Marks, or striations on a bullet are made from the bullet running against the metal of the gun. The barrel of the gun determines whether the bullet curves to the left or right.
