However, QuickLOAD has limitations, as it is merely a computer simulation. It does not 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 ...
The name, Mach IV, comes from the claim that the bullets can reach 4,000 ft/s (1,200 m/s; Mach 3.6). [4] Due to the relatively small case capacity, even small variations in powder of 0.5 gr (0.032 g) can lead to the difference between a safe and dangerously over pressure load.
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 ...
Development of VLD bullets has focused on reducing a form factor defined as the sectional density divided by the ballistic coefficient. [2] Form factor can be minimized by: bullet nose design incorporating a secant ogive, tangent ogive, Von Kármán ogive or Sears-Haack profile [3] the use of tapered bullet heels, also known as boat-tails [1]
Common rifle cartridges, from the largest .50 BMG to the smallest .22 Long Rifle with a $1 United States dollar bill in the background as a reference point.. This is a table of selected pistol/submachine gun and rifle/machine gun cartridges by common name.
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.
An 1858 New Model Army black-powder cap-and-ball revolver replica. The cylinder has been removed from the frame. The modern revolver circular speedloader holds a full cylinder complement of cartridges in a secure fashion, spaced in a circular configuration so as to allow the cartridges to drop simultaneously into the cylinder easily (although non-circular types such as half moon clips are very ...
The cartridge allows for using a large-caliber rifle for varmint shooting, although the accuracy is somewhat diminished. [ 1 ] The advantage, however, is the extremely high muzzle velocity from factory-loaded ammunition.
