According to Wikipedia, rifling was invented in the late 15th century by one Jaspard Zoller in Vienna and improved by August Kotter in Nuremberg. This statement was not given any reference supporting it.
I had read in several places over the years that rifling was invented somewhere in Switzerland during the 15th century, but it was not known who the inventor was.

Rifling in the barrels
Rifling was invented in the late 15th century. It was improved by August Kotter of Nuremberg in 1520 and by others later. There is a link below.
Muskets have smooth bores and rifles have rifling - spiral grooves to make the bullet spin. Rifles have longer range and better accuracy. Both were originally muzzleloaders, but rifles eventually began to use metallic cartridges.
If you are asking when the first guns were made they were first made in China during the 13th century for use as a signal. Springfield rifles were among the the first breech loading rifles in1865.

Ballard style rifling is a type of rifling pattern characterized by its distinctive, polygonal grooves that have a rounded cross-section. Developed in the mid-19th century by the American gunsmith Charles Ballard, this rifling design is known for improving accuracy and stability of the projectile during flight. The grooves are typically deeper and wider than traditional rifling, allowing for better grip on the bullet. Ballard rifling is often found in single-shot rifles and is appreciated for its performance in both target shooting and hunting.
Rifles have spiral grooves cut into the inside of the barrel, known as rifling. Muskets are smoothbore. Rifling causes the bullet to spin in flight, permitting accuracy at long ranges. Also slower to load.
The origins of rifling are difficult to trace, but some of the earliest practical experiments seem to have occurred in Europe during the 15th century.
ALL rifles have barrels that contain "rifling". This is usually in the form of spiral grooves cut into the inside of the barrel- a few have a non-round barrel, with flat surfaces that twist as you go up the barrel. At one time, ALL shotguns had smooth bores- no rifling. However, SOME shotguns now have barrels with rifling, used to shoot slugs. They are still not rifles, as they are meant to shoot shotgun shells.
Micro groove rifling is a type of barrel rifling characterized by very shallow grooves cut into the bore of a firearm's barrel. Unlike traditional rifling, which features deeper grooves, micro groove rifling typically has more grooves that are narrower and shallower, allowing for a smoother bore. This design can enhance bullet stability and improve accuracy, particularly with certain types of ammunition. It is often used in rifles and handguns to optimize performance while reducing the potential for fouling and wear.
