Before visiting a firearm accessories Albuquerque store,
beginners should know a little more on the subject than just the various types
of bullets and their sizes. Performance is more important than size and it is
influenced by several elements that can be difficult and time-consuming to
explain in full. However, with a basic understanding of what they mean, anyone
should be able to choose their ammunition according to their interest and
purpose.

The term “ballistics” derives
from the Greek “Ballein,” meaning “to
throw.” Like balls, when fired, bullets follow a trajectory and
are assigned a velocity.
These two are the main elements determining the bullet's performance.
Bullets do not follow a straight-line trajectory, but they are lifted in the
beginning and start to drop as they lose velocity and approach their target.
Their trajectory
depends on the distance between the point of aim (POA) and the point of impact
(POI), as well as on the velocity of the bullet being fired. Usually, bullets
follow arc trajectories, used to define how difficult or easy it is to shoot a
particular bullet type. For example, flat shooting rounds, such as the 5.45 or
the 5.56mm are easy to hit due to the fact that their trajectory undergoes little
change in terms of elevation.
Upon impact, the
bullet receives an “energy” rating, generally measured in lbs. per sq. inch and
calculated based on a formula that uses the velocity and the mass of the
bullet. Thus, a bullet’s kinetic energy equals its mass times its squared
velocity. The formula would look as follows.
Ek=1/2 mv2
Bullet Stopping Power and Its Implications
The above kinetic
energy formula is actually used to calculate “stopping power,” which is the
theoretical energy transfer amount required to leave a person “halt.” Most
people choose their firearms based on their stopping power needs, but firearm
accessories in Albuquerque specialists warn that the higher the bullet's
stopping power is, the higher amount of recoil the person firing will
experience.
According to Newton's
motion laws, the target struck by a bullet experiences an impact lower than or
similar to the impact felt by the person pulling the trigger. Otherwise put, firearm users have no numerical
threshold to rely on when it comes to producing ‘stopping power’. That is why,
depending on the intended use of the gun, specialists recommend that their
choice be based on firearm size, noise level, distance and comfort of use.
Since sports, hunting and personal defense are completely different
fields of use and have different requirements, beginners may benefit from the
advice of a professional. Luckily for them, most firearm accessories Albuquerque
stores are run by passionate people who do not mind sharing their expertise and
assisting their clients in making the best decision when it comes to the
firearms and the ammunitions they buy.
