When the pressure builds up high enough to overcome the crimp friction between the projectile and the case, the projectile separates from the case and gets propelled down the gun barrel, imparting high kinetic energy from the propellant gases and accelerating the projectile to its muzzle velocity. The projectile motion driven by the propellant inside the gun is known as the internal ballistics.
After a week of playing with my write-up, talking with Rich Rains and others, and wondering what happened in 1928, it struck me – what if they started the half-year system in 1928, continuing the alphabet but now using two letters to a year and deleting the same letters the gun barrel guys did. It would look like….
Neovisno od aktivnosti čišćenja i provjere koju vrši preduzeće za kontrolu sistema za odvod produkata sagorijavanja, korisnik gasa mora voditi računa o sljedećem:
A bullet can be made of virtually anything (see below), but lead is the traditional material of choice because of its high density, malleability, ductility, and low cost of production. However, at speeds greater than 300 m/s (980 ft/s), pure lead will melt more and deposit fouling in rifled bores at an ever-increasing rate. Alloying the lead with a small percentage of tin or antimony can reduce such fouling, but grows less effective as velocities are increased. A cup made of harder metal (e.g. copper), called a gas check, is often placed at the base of a lead bullet to decrease lead deposits by protecting the rear of the bullet against melting when fired at higher pressures, but this too does not work at higher velocities.

Aluminum-cased cartridges are available commercially. These are generally not reloaded, as aluminum fatigues easily during firing and resizing. Some calibers also have non-standard primer sizes to discourage reloaders from attempting to reuse these cases.
9 × 19 mm Mek-Porek The brightly colored ECI is an inert cartridge base designed to prevent a live round from being unintentionally chambered, to reduce the chances of an accidental discharge from mechanical or operator failure. An L-shaped flag is visible from the outside so that the shooter and other people concerned are instantly aware of the situation of the weapon.

I searched up "12th generation intel" to see when the 12th gen Intel CPUs came out (they came out in 2021), and if I try to delete it, I get an error that says, "Couldn't remove item from history." Why?
