All about Bullets
Brass
Brass is the cartridge or the metallic package which contain the bullet, gunpowder and primer (percussion cap) that is a perfect fit
for the firearm’s firing chamber. Normally, a brass is categorized according to the caliber of the bore of a firearm and according to the type of the fire arm. The
case of the firearm could be something like a pistol or a rifle. It is also essential to know that the brass differs from
one manufacturer to another. Being a reputed Swedish amminition manufacturer, Norma stands as a good
example as it has a good reputation in the industry for manufacturing high quality brass.
What Are Cast Bullets?
Cast
bullets are casted out from custom molds. The reasons for chosing cast bullets
are a many. The first reason is that you get a chance to customize and mold the bullets according to specific calibers and diameters. Cast bullets are known to give you the precision of a handgun and
even, that of a rifle. High quality cast bullet suppliers exist in
almost all over the country. These cast bullets work exceptionally well in handguns and rifle bullets are also offered by some suppliers although they are only designed for smokeless loading.
Usually, these bullets are casted out from a lead alloy which consists of lead, antimony, tin and silver.
Discover the Story Behind Lead Bullets
Lead bullets gave
trouble all the way. For example, when they grind with the firearm bore, a signicant amount of lead residue was left behind. So firearm barrel needed constant cleaning after fire off of lead bullets. In order to rectify this issue, jacketed bullets were invented. In jacketed bullets, the lead core of the bullet is wrapped around a thin copper case so that any lead parts of the bullet would not touch the
bore of the firearm. The bullet is usually produced by forcing a lead in to a cup shaped copper case. However, most copper cases
are made of an alloy called gliding metal that contains about 95% copper and 5% zinc. This alloy is used as it is much harder than pure copper and leaves much less copper residue
behind. Even though, some residue is left in the gun barrel after firing these bullets, it is much far less
compared to lead bullets. In addition, this does not seem to affect the accuracy of the bullet. Jacketed bullets are available for both handguns such as pistols and also
rifles.
