A speed load is quite similar to a regular reload of a weapon, but when well performed can afford a large speed advantage. With closed bolt weapons, the speed advantage is lost if they do not have a round in the chamber, as the gun will then require cocking with the new magazine inserted to chamber the first round.
Rate of fire is the frequency at which a specific weapon can fire or launch its projectiles. This can be influenced by several factors, including operator training level, mechanical limitations, ammunition availability, and weapon condition.
A Smith & Wesson Model 66 revolver, displayed with two speedloaders. A speedloader is a device used to reduce the time and effort needed to reload a firearm. Speedloaders come in a variety of forms for reloading revolvers, or the magazines used with other types of firearms such as rifles and shotguns.
Speer Gold Dot 124gr 9mm+P in SIG P226 magazines. Overpressure ammunition, commonly designated as +P or +P+ (pronounced Plus-P or Plus-P-Plus), is small arms ammunition that has been loaded to produce a higher internal pressure when fired than is standard for ammunition of its caliber (see internal ballistics), but less than the pressures generated by a proof round.
Magnum pistol cartridges reverse this power/accuracy tradeoff by using lower-density, slower-burning powders that give high load density and a broad pressure curve. The downside is the increased recoil and muzzle blast from the high powder mass, and high muzzle pressure. Most rifle cartridges have a high load density with the appropriate powders.
Breech-loading provides the advantage of reduced reloading time because it is far quicker to load the projectile and propellant into the chamber of a gun or cannon than to reach all the way over to the front end to load ammunition and then push them back down a long tube – especially when the projectile fits tightly and the tube has spiral ...
It uses a cylinder with multiple chambers, similar to those of a revolver handgun, to speed up the loading-firing-ejection cycle. Some examples are also power-driven, to further speed the loading process. Unlike a rotary cannon, a revolver cannon only has a single barrel, so its spun weight is lower. Automatic revolver cannons have been ...
Components of a modern bottleneck rifle cartridge. Top-to-bottom: Copper-jacketed bullet, smokeless powder granules, rimless brass case, Boxer primer.. Handloading, or reloading, is the practice of making firearm cartridges by manually assembling the individual components (metallic/polymer case, primer, propellant and projectile), rather than purchasing mass-assembled, factory-loaded ...
