A semiwadcutter (SWC) or flat-nose is a type of all-purpose bullet commonly used in revolvers.The SWC combines features of the traditional round-nosed bullets and the wadcutter bullets used in target shooting, and is used in both revolver and rifle cartridges for hunting, target shooting and plinking.
Cast bullets require a longer bearing surface than jacketed bullets to maintain an equivalent alignment with the bore of the firearm; because the softer cast bullet can be more readily deformed. The most successful cast bullet designs have a round or flattened nose rather than a long, unsupported ogive.
Four .30 caliber (7.62 mm) hollow point bullets. Each of the three round-nose bullets on the left has a small cavity at the jacket opening on the leading tip of the bullet. Such bullets are sometimes called open-point bullets, as opposed to soft-point bullets where the lead core extends forward of the jacket.
Examples of FMJ bullets in their usual shapes: pointed ("spitzer") loaded in the 7.62×39mm rifle and round-nosed loaded in the 7.62×25mm pistol cartridges A full metal jacket ( FMJ ) bullet is a small-arms projectile consisting of a soft core (often lead ) encased in an outer shell ("jacket") of harder metal, such as gilding metal ...
Hard cast solid bullet (left), with gas check (center) and lubrication (right) A modern centerfire cartridge consisting of the following: 1. bullet, as the projectile; 2. metallic case, which holds all parts together; 3. propellant, for example gunpowder or cordite;4. rim, which provides the extractor on the firearm a place to grip the case to ...
Reloading the 8×56mmR Mannlicher can be problematic, due to the .329" groove diameter of the barrel. Commonly available .323" 8mm "S"-bullets will produce very poor accuracy. Open-base jacketed bullets, such as the .323" 244 grain round-nose FMJ bullets used in the 8×50mmR Mannlicher, will often produce better results but are difficult to obtain.
Flat nose lead (FNL): Similar to round nose lead, with a flattened nose. Common in cowboy action shooting and plinking ammunition loads. Total metal jacket (TMJ): Featured in some Speer cartridges, the TMJ bullet has a lead core completely and seamlessly enclosed in brass, copper or other jacket metal, including the base.
A spitzer bullet (from German: Spitzgeschoss, "point shot") is a munitions term, primarily regarding fully-powered and intermediate small-arms ammunition, describing bullets featuring an aerodynamically pointed nose shape, called a spire point, sometimes combined with a tapered base, called a boat tail (then a spitzer boat-tail bullet), in order to reduce drag and obtain a lower drag ...
