Trying the accuracy question one more time...

[hitech]

Now that there was been all the discussion about accuracy and not blindly accepting what is written I want to again ask WHY does a "good" paint to barrel match improve accuracy (I accept that more consistent is more accurate). Why isn't a "tighter" barrel just as accurate as a "properly" matched barrel? There would be increased friction, which would reduce efficiency, but what does efficiency have to do with accuracy?

Please don't post, "just get a freak". I'm questioning a popular theory because I don't understand WHY it works.

Thanks in advance.

Wouldn't you get more barrel breaks in a tighter barrel?
That's why we don't get tighter barrles...

If the barrel is too tight you're gonna bust balls.

I can understand that. What is tight enough to break balls? My stroker has what seems to me to be a "tight" barrel (tighter that a Dye something or other, SP Progressive and stock mini mag barrels) put it NEVER breaks balls in the barrel. The only breaks I get are "chops".

Also, do you think a tighter that optimum fit is less accurate?

Thanks.

Does anyone know the answer? Does anyone care?

The barrel would have to be perfect if it was a tighter than optimum fit. If the barrel inside was just a bit oblong it would throw the accuracy out the window but that's the same for any barrel. The only difference is that it would be more noticable.

there seems to be a general agreement that this is how you make sure the paint is the right size:

take off your barrel
place a paintball in the gun-side of the barrel
if you can blow it through with a light puff it is good

if it rols through it will decrease efficiency and maybe accuracy

if it wont blow through you'll get breaks, like everyone said.

Well the reason your Stroker doesn't brake balls down the barrel is because it is smaller in the breach than the middle of the barrel. I can't remember the exact numbers but they usually go from .689 to .700 and then back to .689 or so at the muzzle. It is just the way PPS hones their barrels. But for most of the barrel lenght the bore is larger than it is at the ends. I have no idea why the PPS barrels work so well, I just know what on all of the PPS markers I've had, they shoot pretty much all paint well.

Very interesting. I did not know that. Glenn never mentioned it. I'll have to ask him about that. Thanks.

probably wrong, but.......

if you have an optimum fit, when you shoot the ball, the air pressure behind it shoots the ball without any air going in front of the ball. that means it comes out straight without any air pushing to either side. if you have a barrel that has to large of a bore, air will get in front of the ball. when the paint catches up, it will get bobbled in the barrel so when it finall exits, it's not going to be going straight on target. if the bore is to small, well that is obvious. that what is what i've seen and does seem logical. correct me if i'm wrong anyone.


my question is that if the latter half of a barrel is a larger bore than the first half(IE:freak, 2 piece barrels), wouldn't the air escape around the ball before it hits the porting anyways? that would then, in theory cause the ball to bobble around before it exited the barrel.

They call it "elliptical honing". And I'm pretty damn sure they do it to Strokers, I know they do to Typhoons, and Blazer barrels.

I'll have to ask him about it. Mine is a VERY old conversion (1991) so MAYBE he didn't do it back then. You never know. Glenn likes to talk, esp. about his products. I'm sure he will be glad to discuss it with me. I'll post the results when I get a chance to talk to him.

part one of my message is off topic.. but i cam here about an hour ago, and footemps had 15 or 16 posts, now he has 31!! wow amazing...


now for the 2nd part..

im assuming, being the blunt reader i am, that the better the match, the less the ball will "wobble" on the barrel, so the air can push on the ball with a constant force. If the ball can move in the barrel, it can upset the flightpath.

Look, posting a lot doesn't mean I make useless posts. Don't assume I just post useless crap because I want to get my post count up. If I did I would have flooded the forum a lot earlier.
AND...

He isn't asking about bigger bore, he's asking about tigher bore. There would be no ball wobble if the ball was in a bore smaller than the ball. This is just for clarification...

hey foo, i wasnt flaming or anything.. its kinda funny, dont take it seriously!!



and i said that i suck at reading when im tired, so bear with it..
