    Testing the quality of paintballs

    Taken from automags.org

    Have you noticed and increase in complaints about paint breakage in the past few months? Do you know that pros with the super tuned guns are dealing with it too? Like to know if it's your gun or your paint? Well read on because this is my fourth installment of Tech Tips designed to inject your brains with knowledge.

    Paintballs are made in a 100 year old crude but finely developed process that no one thought would work. The fact that paintballs are as good as they are is really amazing. They are made by pulling two sheets of gelatin, sort of like the Jello stuff, through two pinch rollers. The rollers have holes in them which act like cookie cutters and stamp out the round shape and seal the edges. This is equivalent to taking a piece of round pipe, heating it up the end, press it into a plastic bag laying on the table and trying to seal and cut the plastic at the same time. Now you have to also fill it with goo. We'll try the same thing again but this time you stick a needle between the bag layers, then press the pipe into the bag and seal the needle in the process. Here is the tricky part, you now fill the bag full with goo but don't press hard enough to cut the bag just pinch it closed and seal it. Right when the bag gets completely full you yank out the needle and finish cutting and sealing the bag. Your left with a flexible bag of goo, maybe it leaks maybe it doesn't.

    In paintball manufacturing the balls come out of this process all rubbery, flexible and oversize. They really look more like water balloons than paintballs. In order to get them stiff and round they are dried carefully in a tumbling process that takes the moisture out of the gelatin. This is the key point, getting the moisture out. You all know that humidity affects your paint and if you get it wet it goes to hell. Perhaps you have seen paintballs sitting under a bush at your field that look huge and rubbery, that is the extreme example.

    In the past couple years or so it has been fashionable for pros to demand more fragile paint that will always break on impact. This idea of more fragility has spread around the industry and a lot of the paint appears fragile now. I am concerned about this because it is putting a lot of blame on all the guns and pressure on us designers to fix it. Besides that, paint that gets old or is not properly stored tends to get more fragile. So now you can have bad paint being passed off as tournament quality because "that's how they like it"

    So how do you know what you have and how do you test it? That is the subject of this tech tip. It is actually a tried and true process called a Bounce Test. We have used it for ten years to determine what type of paint we have and how it will work in the guns. In order for this test to have significance you must do the same thing every time and don't cut it short. Start with 10 paintballs, take one paintball and drop it from about 6 feet and let it hit a hard concrete surface. Catch it on the first bounce, do not let it bounce twice in one drop. Now with the same paintball drop it again from six feet, catch it and repeat until it breaks. Mark down how many bounces it took to break that paintball and then repeat with the other 9 balls. Throw out the high and the low numbers and average the other 8. This gives you the "bounce number" for the paint. Simple but effective. Make sure you use a hard surface not a wood floor etc.

    So what does this bounce number tell you? 1-2 bounce paint is super fragile and will break down the barrel in most guns just from the air blast. It will also break in your tubes if you don't pack them tight. 1-2 bounce is pretty worthless paint, you can get it at Wall Mart. 2-3 bounce is considered fragile tourney paint, breaks on people and in the guns too. We are now seeing some field paint at this level. 4-6 bounce paint is good all around and considered fresh. It goes through most guns very reliably but will bounce more often on long shots. 6 and higher used to be considered the best tourney paint in the early 90's because it would go through the guns and never break. Nelson paint was very notable at 8-9 bounces. This paint is hard to find these days but still fun to shoot. Great for big games and when you just want to shoot a lot and not worry about anything. The best thing about high bounce paint is that as it gets older it still works pretty good. 2-3 bounce paint goes to unusable 1-2 bounce pretty fast.

    So now that you know what you have, what do you do about it? Well we have a fix for that too. Back to the idea of moisture, by controlling the moisture in the paint shell you can adjust the bounce level but only to a certain extent. If your paint is too fragile you can generally move it up one category by setting the bag on a table, opening it up and placing a standing glass of water inside the bag and closing it back up. Let it sit overnight and your paint should move up one bounce category. If it's too bouncy (not likely lately) then you can leave the bag open over night and unless your in a humid area the paint should get a little more fragile. All of this is true for standard gelatin paintballs, we have NOT tested the new dry paints so we are not sure if the same thing applies. Test it yourself and let us know.

    My opinion is that the pendulum has swung too far the other way right now and paint is too fragile. This fragility is masking poorly stored paint and millions of rec players are dealing with broken paint when they shouldn't have too. When doing the bounce test note the variation in how many bounces it takes to break the ball. If it ranges from 1-8 then it's inconsistent and will give you problems. Good fresh paint consistently breaks between 4-6 bounces and is worth what you pay for it. As with many things in paintball this test is under utilized to diagnose problems. Take it to heart and show your friends, a little knowledge goes a long way. I want to hear about you guys putting this info to use!

    you should mention the fact that the paint inside the paintball is a liquid (obviously), so after it has been sitting for a while the paint can settle and cause the balls to not fly straight. This can be avoided by shaking the bag a bit before opening it.


    Also you have to consider the safety implications of extremely hard paint (spec ops style). Im sure you are aware of the fuss that was made after some spec ops was being shot and cracked a hopper. Markers shoot 15 bps easily now, unlike back in the nelspot days. So instead of getting shot by one paintball you can easily get shot by at least 5 from closer range in the case of sup air style 'ball.


    Also I disagree with the fact that if paint is slightly old so it becomes more fragile then it is "bad paint". This is subjective, as to a woodsballer it may be "bad paint" but if its guaranteed to break on impact of even padding then to a sup air tournament player it may be good paint. Wine ferments gets better as it ferments because that is how we prefer it, so if we let paint sit for a while and become more suited to our needs, it is not "bad paint"

    Hmm personally, i feel the way guns are today, paint should break when dropped from waist height, first time. Anything less and your chucking games away.

    http://en.wikipedia.org/wiki/How_It's_Made

    Hosts
    Lynne Adams - Season 6 - present (2006 - present)
    June Wallack - Season 5 (2005)
    Lynn Herzeg - Seasons 2 - 4 (2002 - 2004)
    Mark Tewksbury - Season 1 (2001)
    Additionally, a different voice-over track is recorded for U.S. audiences by Brooks T. Moore (Seasons 1-8, 2001-2007) or Zac Fine (Season 9 - 2007-present). The main difference in the versions is that the U.S. host gives units of measurement in United States customary units instead of metric units. At one point in the U.S. run, a subtitled conversion was shown on-screen over the original narration instead.

    In April 2007, all episodes run in the United States (on the Discovery Channel and Science Channel) had the individual season openings replaced with a new opening used for every episode. Additionally, similar to most other Discovery Channel shows, the credits now run during the last segment, with only a blue screen and the request for feedback (and the website) at the end.

    In September 2007, the 9th season began airing on Science Channel, along with new openings, graphics, shot in high definition, soundtracks and a voiceover track provided by Zac Fine replacing Moore.

    In the UK, rest of Europe and S.E. Asia, the series is narrated by Tony Hirst. All episodes have been shown in the UK on the UK Discovery Channel.

    I have been playing for over ten years now so i have been shot a fair few times.

    I got rather annoyed at a big game i attended where i got a bounce of the goggle lens and two bouncers to the head. I have been mugged in the head enough times, used to play the snake, to know that i should not have felt dazed from a ranged shot.

    I found out that some guys were using some seriously hard paint as it was the only stuff that would go through there markers without smashing.

    I know lenses are tested to 600 fps but how do they react to a solid round. Anyone care to blast a lens with a 600 fps reball!!
