QuickLOAD is an internal ballistics predictor computer program for fire arms. Internal ballistics, a subfield of Ballistics, is the study of a Projectile 's behavior from the time its Propellant 's igniter is initiated until it exits For computations apart from other parameters

must be entered for calculating an estimated maximum chamber gas piezo pressure, muzzle velocity, muzzle pressure and other relevant data. A cartridge (also known as a "round" packages the Bullet, Gunpowder and primer into a single metallic case precisely made to fit the A bullet is a solid Projectile propelled by a Firearm or Air gun and is normally made from metal (usually Lead) For the fictional characters see Gunbarrel (Transformers. A gun barrel is the tube usually Metal, through which a controlled Explosion A propellant is a material that is used to move ("propel" an object

The QuickLOAD interior ballistics predictor program also contains the external ballistics predictor computer program QuickTARGET. External ballistics is the part of the science of Ballistics that deals with the behaviour of a non-powered projectile in flight QuickTARGET is based on the Siacci/Mayevski G1 model and gives the user the possibility to enter several different BC G1 constants for different speed regimes to calculate ballistic predictions that more closely match a bullet's flight behaviour at longer ranges in comparison to calculations that use only one BC constant.

QuickLOAD has a default database of predefined bullets, cartridges and propellants. A Computer Database is a structured collection of records or data that is stored in a computer system Data can later be imported or entered by the user to expand the progams database. The default database contains more than 1800 projectiles, over 840 cartridges and over 160 powders. The default database contains some errors, so measuring sizes, weights and case capacities of components intended for use and if appropriate correcting default provided data is wise to avoid surprises and make the predictions more accurate.

Some default data is uncomplete, since it was not released by the manufacturer or when components that are neither officially registered with nor sanctioned by C.I.P. (Commission Internationale Permanente Pour L'Epreuve Des Armes A Feu Portative) or its American equivalent, SAAMI (Sporting Arms and Ammunition Manufacturers’ Institute) come into play. The Commission Internationale Permanente pour l'Epreuve des Armes à Feu Portatives (Permanent International Commission for Firearms Testing - commonly abbreviated as C The American Sporting Arms and Ammunition Manufacturers' Institute (commonly abbreviated as SAAMI and pronounced "Sammy" is an association of American Such wildcat cartridges have no official dimensions nor other performance related specifications. A wildcat cartridge, or wildcat, is a custom cartridge for which Ammunition and Firearms are not mass produced

QuickLOAD mainly helps reloaders understand how changing variables can affect barrel harmonics, pressures and muzzle velocities. Handloading or reloading is the process of loading Firearm cartridges or shotgun shells by assembling the individual components (case/shotshell It can predict the effect of changes in ambient temperature, bullet seating depth, and barrel length. However, QuickLOAD has limitations. It is merely a computer simulation. It doesn't account for different brands of primers for example, and its ability to predict the effect of seating bullets into the rifling is crude. A QuickLOAD user most certainly should not just "plug in" a cartridge, bullet and powder and use that load, assuming it is safe. It is good practice to double- or triple-check QuickLOAD's output against reliable load data supplied by the powder producing companies. Of course the best way to check firearms cartridge loads are actual proof test measurements at certified test facilities. A proof test is a test wherein a deliberately overpressured round is fired from a Firearm in order to verify that the firearm is not defective and will not explode

Since version 3. 0 QuickLOAD is supplied on a CD-ROM. CD-ROM (an initialism of "Compact Disc Read-Only Memory " is a pre-pressed Compact Disc that contains data accessible to but not writable The previous versions were supplied on a diskette. A floppy disk is an increasingly Obsolete data storage medium that is composed of a disk of thin flexible ("floppy" Magnetic storage medium encased
