Paintball Myths Revealed:
Accuracy, Trajectory, Distance

Mike Whitmer


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, bottomline, 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.

Oh yeah: don't give me any grief about the copyright notice. It's an article I am being paid for, so it has to be there.

on the accuracy thang there...you said that no gun is more accurate than another.

well here are three contradictions

we all know that a good paint to barrel match means good accuracy. so a guy with a small bore barrel and large bore paint is going to get the same accuracy as someone with a medium sized barrel and medium sized paint ()

AND. someone with a brass eagle vs someone with a shocker. now, you cant tell me the shocker won't shoot a hellova lot farther and more accurate than a piece of eagle?!

the third contradiction:
someone with a barrel that has no porting IS going to have worse accuracy than someone with a ported barrel (ie someone with a threaded pipe vs someone with a sp teardrop).

something wrong with the trajectory myth too!
are you going to stand there and tell me that the tippmann flatline or the automag zbody is going to have the same trajectory as a spyder? nope!

this isnt directed towards you paintballerx.

First off, I covered paint/barrel matching in the very beginning.

Second: certain markers do decelerate faster than others which can, in turn, make them not go quite as far as others. However, scientifically speaking and in a perfect world, every marker goes the same distance.

Porting does nothing for accuracy. It helps with making the barrel quieter, and that's about it. The only differences that aftermarket barrels have over most stock barrels and a pipe (?) is that they are honed and bored to an exact specification for the purpose of having a smooth, generally flawless interior.

I was not referring to the "freaks of nature" (as I call them) like the Z-Body and Flatline. Those are modifications to existing markers.

If it's not directed towards me, then who?

the dude that wrote the artical...unless...YOU wrote the artical

why doesnt that include flatlines and zbodies? i dont get it? its an available product for markers. are you saying that those markers dont count becuase they are modified? i know porting doesnt do anything for accuracy but it sure does help. take the wisper barrel or the crown point barrel. the crown point and wisper barrel both actually help with accuracy.

Judging from the fact that my name is plastered all over the article and I included a copyright notice, I'd be inclined to think it was me who wrote it.

I didn't include anything like the Flatline or Z-Body because they are modifications to existing markers and it wouldn't be fair to compare a normal marker with a Flatlined (?) one.

I'm not quite understanding your point about the Whisper and Crown Point. Porting does nothing for accuracy, it only helps to make the barrel quieter.

psh how am i supposed to know thats your name?!


i seriously dont see why zframes and flat lines shouldn't be included. or if you want to play that way, ill mention the flatline autococker that COMES with a flatline.

now for the crownpoint/whisper

the way these barrels work is that the weird porting gradually 'introduces' the paintball to outside air pressure eventually, making for less air turbulance behind the ball.

I don't understand why you don't get this. I am comparing standard markers v. other standard markers. If I threw a marker upgraded with any of those contraptions into the mix, it would completely destroy my experiments and conclusions.

Hate to break it to ya man, but the Crown Point doesn't have ANY porting. At all. The Whisper has a whole helluva lot of it, but what you're talking about is a theory that is extremely easy to disprove---in fact, it has been numerous times.

Seems to me that you rely to much on what other people say and not enough on what you have personally experienced.

do you really think that people keep their guns stock? nope. i dont see the purpose in your "tests and experiments" in the first place. basicly EVERYONE, save a few people, upgrade their markers with new barrels, bolts, and other strange crap that increases accuracy and distance.

the crown has a muzzle break. thats what im talking about. im sorry, i ment the muzzle break, but it does introduce it to the outside air better with less turbulance like with the wisper as well. the porting gets bigger and bigger introducing it to more outside air. i DONT believe everything people tell me. if that was true i'd have about every marker available right now.

Look, bro: I could care less if you see the purpose in my experiments and tests. I wrote this article to help people, and help it has and will. Unfortunately, you continue to try to disprove my comments with ficticious or poorly written explanations of why I'm wrong.

Come on, work with me! If I were to try to take into account EVERY UPGRADE available, I literally would be 95 years old before I finished!

whoa there buddy. i know you're trying to help people but you have to understand that NO ONE IN THE DAMN WORLD keeps their gun stock. you are helping people. that is good. BUT you didnt mention in the artical that upgrades would tamper with the facts you put up. just helping YOU out a little

well mike i hate to be a wise ***

o wait to late

but it's been proven ive seen it with my own eye, i don't care what u can say ive seen it on many an occasion with different guns

i have people that will back me up

an angel does not have the same arc of the ball a cocker does, it has a sharp drop off and relatively shorter range, although the range is quite acceptable to most speed ball player u simply can't get the long ball on the larger fields

don't argue mike, ive seen it with my own eye u can't change that, look in the fly II review alot of people say the same thing, i dunno if it says it in the others but i can guaranty it's in there

but over all good report i dun feel like nit picking much more

While what you have seen may have convinced you, it hasn't gotten me yet. As I said in the article, all the points stated are in reference to a perfect world, the technical aspects of paintball. Obviously we don't play in a vacuum, so this won't apply in it's entirety to real life. However, there are a few variables that could have changed between the two markers you tested. Perhaps the Angel had a low tank of air? Perhaps the barrel wasn't sufficiently polished and created excess drag? You don't really know, do you? So, please, by all means, hold a dedicated test on the range differences between both markers and report back. Until then, all you have is "what you saw"---which is wholly unsatisfactory for all intents and purposes.

Thanks for the comments.

Thick headed people are so...!

Like I said before, until you do a test with all variables present in check, benchmounted, with a witness or three, etc., I simply don't believe you.

ive done benchmounted ive done comparisons with multiple guns

and many many people agree to me

ie the lack of angels down at sc villige and in many more "hot spots" of paintball

hey, thror! you need to shut your hole and deal with it! he has helped people and beleive it or not there are more people who leave guns stock than people who upgrade the crap out of em. i myself have a stock gun and i know a whole bunch of other people who have stock guns as well. c'mon, give the dude a break, he's trying to help people
