Action or reciever
um well i dont really understand your question but the bolt of a rifle loads in the shell and the fireing pin strikes the primer making it fire off the round. same thing basically for shotgun shell unless its a pump but the fireing pin is the same usually
You must define what type of firearm you are talking about.
They function fine. You pull the trigger, it can be expected to shoot. It's a well engineered firearm, and can handle the pressure generated by the cartridges it fires. It's plenty reliable. Now, practicality, on the other hand, is a much different matter.
"Magnum" refers to the cartridge, not the firearm. The Desert Eagle fires Magnum cartridges. What you're probably asking is the difference between a revolver chambered for Magnum cartridges, and a Desert Eagle semi automatic pistol. Of the two, the revolver would typically be much more practical.

Load, squeeze trigger.
When it fires with very little pressure on the trigger.
A sub-machine gun fires pistol cartridges. A machine gun fires rifle rounds.
its when you have a gun or any weapon that fires bullets.
When a gun fires more than 1 shot per pull of the trigger. In most cases, pull the trigger. Gun fires, ejects fired cartridge, loads fresh cartridge, fires it, and repeats until you release the trigger or run out of ammunition.
Submachinegun refers to a fully automatic firearm that fires a pistol caliber cartridge, such as 9mm parabellum or .45 ACP. Rifle refers to a firearm that is fired from the shoulder, and has a barrel designed to make a bullet spin as it leaves the barrel, increasing its accuracy. Most commonly this is by having spiral grooves (rifling) cut into the inside of the barrel. PS- machineguns and handguns ALSO usually have rifling in their barrels. The lines between a submachinegun and a rifle/carbine have been blurred at times, though. The Heckler & Koch HK33, which fires the 5.56mm cartridge common to the M16, was marketed by the company as a submachinegun, for example, even though it fires a dedicated rifle cartridge. Traditionally, submachineguns fired pistol caliber cartridges (as stated above) and fired from the open bolt. However, designs such as the MP5, which fired from the closed bolt, began to appear, and altered the definitive archetype of what a submachinegun was. And now the Personal Defence Weapon class of firearm is emerging, with new designs somewhere between a submachinegun and a rifle, and with cartridges which are somewhere between handgun and rifle cartridges.
It's both. A crossbow is a modified version of the simple bow. It is also classified as a firearm because it fires a projectile (the arrow or bolt).
