Do you mean "What sound does a rifle make"? If you do, it makes a very loud "pop" similar to shooting a cap gun but about 1o times louder.
A very loud BANG!
Air rifles can push a lead pellet at or close to the speed of sound. Yes they are lethal, and very accurate.
Rifles that can fire a bullet faster than the speed of sound predate cartridge arms. Muzzleloading rifles can reach well over the speed listed.
Smith and Wesson does not build rifles. The rifles they sell are made for them.
No they did not have rifles. They had muskets. They did not have rifles until the late 18th century.
This may sound strange, but if it never HAD a serial number, not a problem. Serial numbers were not required by law on rifles and shotguns until 1968. I have about 20 rifles made in the 1940s and 50s that do not have serial numbers. REMOVING a serial number is a serious crime, however.
