QuickLOAD has a default database of predefined bullets, cartridges and propellants. The database of the more recent versions of QuickLOAD also include dimensional technical drawings of the predefined cartridges and for most cartridges photographic images. Data can later be imported or entered by the user to expand the programs database.
Compared to the 7mm Remington Magnum, top 7mm RUM loads deliver 25% more energy at 300 yards. [citation needed] Such performance demands a price and in this case, that is a large muzzle blast, sharp recoil and short barrel life. [1] The 7mm Ultra Magnum boasts the largest case of any commercial 7mm cartridge.
These are both more energetic by mass than black powder and can produce higher velocities and pressures. Triple Seven is a volumetric substitute for black powder, and due to its higher velocity, it is recommended to reduce the load by 15%. [11] The carbon-based fuel burned in this case is from the sugar family, not from charcoal.
This is a table of selected pistol/submachine gun and rifle/machine gun cartridges by common name. Data values are the highest found for the cartridge, and might not occur in the same load (e.g. the highest muzzle energy might not be in the same load as the highest muzzle velocity, since the bullet weights can differ between loads).
The .375 Ruger cartridge case was used by Hornady as the basis for new long-range cartridges, since it had the capability to operate with high chamber pressures (65,000 psi (448.16 MPa) P max piezo pressure according to the SAAMI), which combined with a neck and barrel throat optimized for loading relatively long and heavy very-low-drag bullets ...
To compensate for this, Waters necked the cartridge down to use a 7 mm bullet (.284 inches), rather than the original .308 caliber (7.62 mm) bullet. Because it was designed to function in lever-action rifles, the 7-30 maintained the same low working pressure, yet Waters' original design fired a lighter bullet (139 grains) at a higher velocity ...
[5] [6] Reloaders have a variety of bullets to choose from, and Hornady lists load data for the cartridge. [4] Reloaders should be aware of whether their rifle does, or does not, have freebore before using load data developed with more modern components. [7] Cases can also be formed from 7mm Remington Magnum cases. [8]
The 7mm WSM has failed to gain the same popularity as the other cartridges in the WSM family. Some people erroneously believe the short case necks make the 7mm WSM poorly suited to heavier bullets, limiting the cartridge's usefulness on larger game. It is no different in this respect than the popular 300 Winchester Magnum. [3]
