Paintball Myths Revealed:
Accuracy, Trajectory, Distance

Throughout the years, I have heard every major paintball misconception played
out in every forum possible: the subway, the local tavern, and heck, even the
local paintball field. A group of paintball-playing buddies get together and
discuss their game, and no matter what, the conversation always turns to how
accurate the speakers’ marker is. While it is true that, when bench mounted in
an area where all variables have been reduced to null, one marker could be more
accurate than another, most people take this fact and run with it. I’m sure
everyone has heard the famous “my marker is more accurate than yours because
it’s a closed bolt!” argument before. And every Autococker owner out there
is sure to have been the subject of a rant by a fellow player regarding how
accurate the marker is because of its flat trajectory. Oh, yes, and let’s not
leave out the “your marker has much more distance than mine” ideal, that
would be heresy! Rolling of eyes ensues.
I still can’t believe that in this day and age, people still think that one
marker is more accurate, has a different trajectory, or shoots farther than
another. The purpose of this article is to inform the masses that the latter is
most certainly not true, and to instruct all of those who break from the chains
of conformity and actually listen on how to get the most out of their paintball
marker. Read on and be enlightened!
Accuracy in Paintball
For all intents and purposes, including those of physics and science in general,
no marker can be more accurate than another because no bolt configuration can be
more accurate than another, in theory. However, in the real world, this idea
rarely plays out as it is intended to. Wind positions, temperature, your FPS
reading, all of these will change on a second-to-second basis. Unless one could
play in a vacuum that were to be kept at a constant temperature, and used
equipment that could keep dead-on consistency at all times, there is no way to
prove that a closed bolt marker is more accurate than an open bolt, or that it
is the same. In fact, any test on the subject is flawed the second it begins,
because of the aforementioned variables present (or absent, depending). There
are, however, several ways to improve or control the accuracy of your paintball
marker. The most important involves the match in barrel and paintball bore
sizes. Even a slight disparity in this match can allow for a severe decrease in
accuracy. The best way to test for a paint/barrel match is called the “blow
test.” In order to perform this operation, simply insert a paintball into one
end of the barrel, and attempt to blow the paintball out of the other end. If it
comes out with some slight force, it should be satisfactory. However, if it
requires a minimal or profuse amount of force to propel the paintball from the
barrel, you have a ball that is either too small or too large, respectively, for
your barrel.
Next up is getting the best air system you can possibly find. Look for one with
a high flow and recharge rate and a well built regulator. The PSI (pounds per
square inch) and CI (cubic inches) of the tank does not affect accuracy. The
final method to improving accuracy is to purchase a high-flow regulator, inline,
bottom line, or sideline (along the side of the marker; a rare find these days).
A high flow will significantly increase accuracy because it will allow more air
to flow inside of the marker, increasing consistency, a major factor in
accuracy. By following all of these steps, your marker should be as accurate as
possible. Keep in mind the effects of barrel length on range and accuracy found
later in this manuscript before choosing your new tubular trajectory correction
device.
The Trajectory Myth
What is this allegory, you say? Well, it is mostly apparent among Autococker
owners who claim that their marker has a “flatter trajectory, meaning better
accuracy at longer distances.” Scientifically this is not the case, as any
claim of one marker having a different trajectory than another is physically
impossible. No matter what the situation, this assertion is always false,
regardless of how much the instigator of this idea tries to explain science
away. There really isn’t a great deal else to say about this fallacy. Simply
know that any declaration of a marker having a different trajectory than another
is invariably fictitious.
Distance Misapprehensions
Regardless of what may be said, there are still some ill-informed, but
well-meaning, players out there who still believe and profess that distance
varies from marker to marker. Allow me to soundly assure you that this is by no
means the case. Closed bolt markers have long been believed to have better
accuracy and, of course, distance (it’s a wonder that most people don’t
think they allow you to fly as well!), than their counterpart, the open bolt
mechanism. Physics state that no bolt operation can make a paintball fly farther
than another, unless modified by another operation. The only other operation in
the paintball world that could change the flight distance of a ball is the
amplification of velocity. This generally is unsafe, and at a certain point, one
will encounter severe ball chopping because of the velocity at which the bolt
strikes the paintball. Some people think certain markers shoot farther than
others because they either held the former marker at a steeper angle, or had a
less consistent setup on the second marker resulting in lower accuracy or
accuracy spikes.
The Affect of Barrels on Accuracy and Distance
One myth that has stood the test of time is that longer barrels give a marker
more distance and more accuracy. This is far from the truth, and the laws of
physics state this in numerous places. One object emitted from a source at the
same velocity and angle as another object, barring drag in the trajectory and
elements such as wind and temperature, will go the same distance and have the
same flight path (accuracy). Now, introducing drag into the equation, one can
imply that the opposite of the idea abovementioned is true: the longer a barrel
is, the less accuracy and the less distance can be expected. Through my own
tests and the tests of such paintball greats as Tom Kaye, creator of the
Automag, the findings are self-evident: the barrel only uses the first six to
eight inches to accelerate, and the next two to four to correct itself before
falling victim to drag, which in turn results in deceleration, which produces a
larger arc, and finally results in less distance and accuracy at longer ranges.
Therefore, the optimum barrel length is at least eight inches and at most
fourteen, with the average at eleven inches. Most barrel makers do not produce
eleven inch styles of their product, so one must either pick between ten or
twelve inch for the most advantageous performance possible.
Blowback and Accuracy
Blowback, defined as the excess gas vented from the marker through various ports
(feed tube, barrel, etc.), is another contributing factor towards accuracy; or,
should I say, the disparagement of it. Closed bolt markers have inherently less
blowback because of their design, which allows less air in the form of blowback
gas to escape. Blowback is essentially the leading origin of kick, or the lack
thereof. Consequently, closed bolt markers will always have less kick than most
open bolt markers. If your marker kicks, it jerks from your grip at least enough
to throw off aim slightly. If you have a closed bolt marker that has less kick
or none that is noticeable at all, your aim will stay true as long as you can
keep your arm steady. This will lead to greater accuracy, allowing you to
consistently place shots in and around the area you intend to hit. This does
not, however, take the place of the skill of the operator. The shooter must use
his own sound grasp of the marker to control the shots.
I trust that this article will assist all that read it. All information in this
text has been checked and double-checked for accuracy. Share this information
with your fellow paintball players, and let the word get out: the prominent
myths of the game of paintball have been disproved many times, and it is time
that everyone participating in our great game realizes this.
