barrel length

[crakonpr]

how much does the length of the barrel effect the accuracy of the ball?.... im debating between a 12 and a 14....would 2" make any diff.? what would u get?

[Cliffio]

accuacy is within the first few inches of the barrel
the next half or so determins how the ball will shoot, shorter barrels and longer barrels will shoot basically the same accuarcy wise

[Trunnion]

it's not the length of the barrel that affects accuracy, it's the match of the paint to the barrel's bore size. there are a bunch of threads about this. if you want more info, you can use the search feature

[crakonpr]

so length does nothign?

[Cliffio]

well length determins how the ball will shoot, for example if your playing a hyperball field and you putting your barrel in a groove, and its 12 inches, your shots are going to go funny because the porting is affected, and a lionger barrel will not because the porting is past the bunker

but length is more of a preference i believe, i dont notice any difference in a 16 in than a 12

[Cliffio]

also longer barrels are quiter than shorter ones

[crakonpr]

word im gonna go with the 12 then thanks

I think it really depends on where you play. When I play speedball, I like a good short barrel, like the 10" Dye Stainless I have. When I play in the woods, I like a 12 or 14". It's not that big of difference. I think a 16 or 18" inch barrel is both ridiculous and a burden. If you only buy one barrel for wherever you play, I'd go with a 12". The accuracy is nearly the same on the 6" venturi to the 14" carbon fiber I have when the paint matches bores equally. The noise and effiency is another thing.

There is your difference.

[FooTemps]

Longer barrels are also less efficient.

[epterry]

foo I think your wrong. in longer barrels the air has more time to push the ball so you wouldnt need to put as much air behind the ball. I know longer barrles dont use as much air as short barrels cause i did a test.:D

I'm guessin you haven't read the tech tips yet huh?

[epterry]

he says best efficient leingth from brech to porting is 8 to 10 in. the 12in. barrel i have is only efftive for 6 1/2 in do to porting so i need a longer than 12 inch barrel to reach maximun efficience so but at some point your right. if useing a crown point you dont need a long barrel.:D

[epterry]

my test was that i took a rely short barrel 3in before porting gased up the marker fired 5 balls over a crono all around 255fps next with out degasing the gun i put on a same sized bore same paint 12in barrel fired 5 balls all came out at about 305fps notice same amount of gas behind each ball :D

[nutz]

epterry did u try a 12" barrel vs a 18" barrel???

i would be interested in those results more than 3" vs 12"

[Jordan-APL]

I like anything between 10-12" that about it,anything longer looks goofy.I saw this kid with a spyder,he had a 21" barrel it was freaking crazy.He said "I am sniper".Needless to say,he was a coward and i bunkered him.

[epterry]

cant find a 18 inch barrel (before porting) and enyways the longest barrel I have is a 12in see im 4ft 10in and 12in is pushen long :D think about it this way ever tried a short blowgun vs a long blowgun?:D

[epterry]

dont forget that 12in was only 6 1/2 be fore porting.:D

[Trunnion]

i have an 18" boomstick which, while goofy, is far quieter than any of my other barrels. i prefer this barrel in the woods. if i can find a concealed position, i can usually score a kill before my position is pinpointed. though i only use this barrel if i have a good paint fit. for most situations i use my 12" freak, which is a great barrel

[epterry]

how much porting on that 18in Trunnion ??
:D

[nutz]

around 12" is my guess cause boomy backs are around 6 inches i believe

i dont under stand what ur saying epterry... why not take a 12" boomy and 18" boomy and chrono them with the same setting then see what happens

[epterry]

sorry thought you were talking about a 18in before porting. that be one long barrel.:D

would if I had the barrels but i dont:D

[Trunnion]

my guess would be 12", like nutz said. i don't have it here at school with me, but 12" is probably about right. i know it's inefficient, but if i can get a kill before being located, i think it's worth it. however, i'd never use the gun in an arena. that'd just be silly :)

[Cliffio]

i have a 20 inch barrel, its very good for sniping and i get soo much extra range with it, i can long ball people from almost all the way down the field, its quite amazing, and im dead accurate many people just stare in aw(sp)

you dont need a barrel thats longer than 12", you can just find a 12" thats got less porting.

Now now don't tease the animals...

I used to know a guy with a yard long barrel, It got extra range... about 24" worth over a 12" barrel when measured from the grip frame... :)

darn, i was hoping some one would get all upset and make comments, but that didnt happen:(

ah well
i thought it was funny:)

Well if you tell us where you put these 'genius works' then we will tell you what we think of them...

I actually tend to beleive that Barrel length has little to do with how many shots per tank you get to a certain degree. From just my own personal testing, ie a 16" All American that I unscrewed the porting on to get around 7" of solid barrel, I notice NO difference in velocity. And from general use no difference in SPT(Shots per tank). What I do notice is the difference in sound and the ability to hide behind a bunker.


I believe that once the ball reaches max velocity in the barrel as long as it does not touch the 2nd stage of the barrel then no SPT are lost and velocity remains the same.

Most 2nd parts or 2 stage barrels are at least .690 or better. So the Ball never touches the outer portion.

Of course this is all armchair calculations although the velocity does not change between the two.

[soilent green]

if you use a two piece length has relativly no affect because effective length is always about the same

[epterry]

so you said without the porting the ball gos at the same fps as with the porting? that would make since so i guess thats what your trying to say?:)

[AzrealDarkmoonZ]

Yes I am saying Ported Barrels and 2 stage barrels are irrelavent in terms of FPS, of course extremely large paint may rub the 2nd stage but we will ignore that arguement.

I am also saying, against common thought, that a 2 stage barrel is no less ineffecient than its 1st stage. That in fact maximum velocity has been achieved before the porting. Thus the porting would just evenly disperse the pressure and making the marker quieter.

It would reason to think that if the 2nd stage made the marker less effecient then the FPS would change, and I would have to adjust the velocity settings, when in fact I do not.
