The QuickLOAD interior ballistics predictor program also contains the external ballistics predictor computer program QuickTARGET. 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 ...
While CUP and LUP numbers were intended to be comparable to the crushing power of a given pressure, the numbers are not equivalent. Since a longer duration, lower pressure pulse can crush the cylinder as much as a shorter duration, higher pressure pulse, CUP and LUP pressures frequently register lower than actual peak pressures (as measured by a transducer) by up to 20 %.
Handloading ammunition avoids the labor costs of commercial production lines, reducing the expenditure to only the cost of purchasing components and equipment.Reloading may not be cost effective for occasional shooters, as it takes time to recoup the cost of needed equipment, but those who shoot more frequently will see cost-savings over time, as the brass cartridge cases and shotgun shell ...
In all instances, it is up to the competitor to ensure his or her ammunition meets the requirements for the competition or equipment division. Effective on 17 January 2011, the power factor for the stock service revolver division (SSR) was reduced to 105 kgr·ft/s since most factory produced .38 special ammunition available on the market did ...
The ball 4.6×30mm cartridge weighs 7 g and is loaded with a 2.7 g full metal jacket projectile with a PbSb-alloy core and a copper-plated steel jacket that achieves 600 m/s (2,000 ft/s) muzzle velocity. The cartridge is designed for the MP7. This ammunition is optimized for energy transfer in soft targets and offers good precision. [12]
This speeds up the process of loading and reloading the firearm as several rounds can be loaded at once, rather than one round being loaded at a time. COL (cartridge overall length): Factory ammunition is loaded to a standard, SAAMI specified, Cartridge Overall Length so that the ammunition will reliably function in all firearms and action types.

Most European ammunition manufacturers load to a lower C.I.P. pressure limit - 380.00 MPa (55,114 psi) P max piezo pressure for the 8×57mm I civilian Patrone 88 offspring - for I-bore cartridges and use 8.08 to 8.09 mm (0.318 to 0.319 in) diameter projectiles; [22] while the US based manufacturer Hornady followed their lead in their (now ...
