This liquid volume measurement method can be practically employed to about a 0.01 to 0.02 ml or 0.15 to 0.30 grains of water precision level for firearms cartridge cases.
QuickLOAD mainly helps reloaders understand how changing variables can affect barrel harmonics, pressures and muzzle velocities.
It is good practice to double- or triple-check QuickLOAD's output against reliable load data supplied by the powder producing companies.
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.
In January 2009 the Finnish ammunition manufacturer Lapua published Doppler radar tests derived drag coefficient data for most of their rifle projectiles.
[1][2] The predictive capabilities of the custom mode are based on actual bullet flight data derived from Doppler radar test sessions.
QuickLOAD is distributed in the United States, Canada, Mexico, South Africa, Australia and New Zealand a by NECO (Nostalgia Enterprises Company) and Europe except Germany, Czech Republic, Denmark, Finland and Ukraine by JMS Arms.
