Dirty Dan's "The Different Diameter Conspiracy"

Efficency aside, isn't the ball detent supposed to keep the balls from rolling out?

Not all paintball markers have ball detents.

[MarkM]

Ball detents were originally only on 'cockers who have a huge varience in breech size to stop the balls from double feeding...the closed bolt operation of the 'cocker actually makes this worse as the balls can and do roll out of the barrel...the mag didn't have this problem since it was open bolt plus it had the spring in the barrel (although without getting into the closed v open debate all paintball markers fire the gas through the bolt to finally propell the ball in the closed postion even if the gas burst began when the bolt was in the open position)...if ball detents were such a perfect development then why do you not see them on pumps (not 'cockers as I covered that above) Now things are different with the force feed loaders so the detent has taken on a new role for which is is actually better suited to than the reasons it was first used, plus the rates of fire could make things get ugly down the barrel without them.

Want to see just how much matching paint to the barrel has on accuracy? Use your barrel kit WITHOUT the insert! Ask cphilip what happened.

Well, would that tell you how much paint to barrel matching matters, or how using your barrel KIT properly/improperly matters? I would say it is the latter.

Well..... In most cases I would say that using ones equipment properly is important. However, this case happened to be different. It shot just as accurately without the insert. Just had to turn up the velocity a tad.

It just doesn't make the difference everyone thinks it does.

On an autococker the ball detent does not prevent roll out. The ball is pushed past the detent before it is fired. So if you shoot and the next round loads. And then you go to run or move and point your barrel down.. you have a good chance of a roll out.

As far as not using your insert I agree with Shartley. I think it just proves you don't know how to use your equipment. A better test would be get a good match. Say using your .684 insert. Then take out the .692 insert and use it. You will not see much of a difference.

AGD has done enough tests about this to make all of Dans thoughts moot. The Ball does NOT conform to the barrel interior, rather it only touches at two points all the way out. You can prove this yourself with some baby powder dusted inside a barrel, and shoot a ball. Look for the two lines etched in the powder, that's the only place the ball touched. That's also why rifled barrels don't work in paintball.

and if you read the whole post, you will see that with a small ball and large bore, the ball bounces back and forth down the barrel. thus having a mismatched ball to bore size will affect accuracy... by how much i dont know. probably not much.

It will affect accuracy only in increments that are measurable with perfectly sized and consistent paintball fired in a vacuum.

In other words: real world difference >> all but negligible.

[Destructo6]

I base this theory on the fact that several experienced airsmiths have told me this happens. So therefore there's no real need to match the paint and barrel diameters.

After criticizing the scientific basis for the pro-barrel matching camp, he commits this sort of error in nearly the same breath? Lets see the science.

[1ofkind]

I agree with the fact bore siezeing doesn't effect accuracy, but only for certain markers. I noticed if you get a tight bore when useing a spyder the shots are defiently straighter, almost until they hit the ground in the distance.

[Lohman446]

Let me say this.. I think in the extremes he is wrong. But I doubt anyoen will notice a difference that matters between .683 and .689 if they use the larger size, jsut barrel breaks with the smaller

[Bad_Dog]

you also must take in account the range that Dan did his tests at... if you're close to your target, its pretty much point and shoot. The margin of diference at close range is miniscule compared to that of a larger distance. Remember if the path of the paintballs vary, it wont be as noticeable at 10ft compared to 20ft...

example..

if you conducted your tests standing 3 feet away from a wall... no duh the balls are all going to hit on top of one or another...



I think that some of your information takes a step in the right direction, but the fact that your methods of prooving your ideas are so vague makes everything seem false.

[Bad_Dog]

Here are a few things that I dont agree with:

Simple. When the ball is fired, it gets compressed and it fits the barrel perfectly.

yet you state later that you buy a large bore barrel so that all paint fits it. I dont think that a paintball would get compressed if the barrel is larger?? and what if the barrel is too small for the paint? I dont recall barrel breaks helping my game anyhow...

I got one of those aftermarket extensions that attaches to the marker where the barrel goes and the barrel is inserted into the extension. These little extensions have a smaller inner diameter to hold the ball in the barrel and prevent roll out when the bolt chambers a ball.

so if your little extension has a smaller diemeter and you use your large bore paint what do you end up with? barrel break, barrel break, barrel break ect....

It just seems to me that Durty Dan is looking for some popularity, allthough the "Durty Dan Fix" is cute, it probably only appeals to those who want to believe in it because they have nothing else to do with their time...

[Bad_Dog]

It seems to me that the two major factors you havent realized is that when you use your little fix tip thingey, your efficiency must go waaaaayy down...

One of the reasons why people use the multibore kits is for efficiency and consistancy...

another major factor is the quality of the paint and its tolerances..... like if your using paintball seconds, theres no way any barrel will match the paint.

I do think that its a good thing to think about and to question something like this is a task none the less. But the way that you introduce this idea with little to no evidence but to trust you and input from airsmiths... is pretty harsh. Then you come to a conclusion without proper testing....

kinda seems cheesy to me...

just my feelings though... $.02
