sweep valve and bolt?

[theymightbecool]

i was looking to buy a new gun when i came across the intercepter. the gun is dead sexy! i've seen vidoes, pics, and read a bunch about it. i really want one, but i wanna kno, whats this whole sweep valve and bolt system. how does it work.

[p8ntball226]

The valve has an oval opening on the top of it and the bolt has and oval opening where the air from the valve is going into instead of the regular circle openings. They claim it reduces turbulence and helps it shoot a flatter trajectory, though all that flatter trajectory is stuff is a myth and is false. The bolt also is closed off at the top half so the air hits the bottom of the ball which they say puts some backspin on the ball. Though if I do remember correctly some other company tried the same thing, well not sweep valve but air hitting the bottom of the ball and it was proved to have no affect.
I'd really recommend getting the gun, its very nice, fast and light, I love mine.

and is the stock trigger good?

[p8ntball226]

yes, the stock trigger is pretty good, I would have preferred it to be a blade or sycthe type triggers though.

"all that flatter trejectory is a myth and is false"
P8ntball 226 -Im glad you like your Interceptor, BUT -if you cut the insert inside your bolt back by say an inch, you would see your shot pattern open up to what everybody else has!!!!!
I am making some bolts that only change the shape of the insert so players can see the difference.
Automag spent a lot of time, effort and money to make everyone believe that it's all paint to barrel match. From now on I will be carrying bolts so players can shoot both ways. Believe what you're told or believe what you see and experience. I no longer believe, I know. :cool:

[p8ntball226]

I have a question though, how exactly does the shape of the air from the sweep valve affect the paintball at all? You're claiming since it's an oval shape of air it'll make it shoot better correct? Well air conforms to the shape that its contained in, so when the air is going down the barrel it's no longer only hitting the bottom or is in an oval shape, its the same shape as any other gun. So then how would the shape of the air from the valve have any affect on the ball?
Also, why is the opening on the face of the bolt not oval? If the valve opening and where the air enters the bolt is oval shouldn't the bolt face be oval too and not a half circle?

The "other company" is Cooper and they made the T-Bolt. Ande it does works. Note that when they tell you that only the paint to bore match is important they alway make it clear that "without any spin put into the ball".

backspin works if you have a slightly oversized barrel bore and good paint. without those two things, its the same or worse than other setups. There is also a company currently developing a paintball that will work very well with this. Its another one of those theories that AGD disproved, and yet, in other testing, seems to actually work.

Dimpled paintballs anyone?

Dimpled paintballs anyone?
aah, looking into the same thing a golf ball uses? this could work. look at bullets, they have grooves in them from the barrel, and they shoot much straighter than non rifled barrel guns. correct me here, but i think that the golf ball's dimples are meant to disrupt the even airflow that comes together behind the ball, adding an area of MINISCULELY lower pressure, adding to the straight trajectory of the ball. so, if you dimpled a paintball, it should, in theory, fly straighter. test. overstiff a pod, and let it sit for a few days. then, dump out all the paint, and put it in the pod again, adding paint as needed to keep the pod filled. do this a few times, then shoot it and see how much straighter your paint goes.

The dimple pattern has to be perfect for it to work. Ie.. manufactured like a golfball with very tiny dimples in geometric patterns. It does interupt the air flow around the ball reducing drag and letting it hold its velocity longer = slightly more distance.

The oval is the width of the opening and reduces turbulence, to have an exhaust that is smaller than the opening restricts airflow. The Half circle is bigger than the oval entrance. Air wants to tumble like a wave as it expands. Allowing the air to spread sideways reduces the tumbling of the air. The half circle is the "Sweep" the air is directed under and around the ball. If you sweep a pile of trash - odd shaped - it goes mostly in the same direction. If you poke through it then it goes off to the sides. A pool cue if hit dead in the middle will go straight, otherwise English.

Again you don't want a knuckle ball, one that will pick up spin randomly as it move through the air. You want a consistent shot – the above mentioned bullet having rifling – and as long as you want some spin then the best spin is a slight back spin, or as I like to say a gyroscopic back turn.

[p8ntball226]

Ok, now I understand it more. I'm going to do some testing comparing it to other guns to see if it really does help accuracy pretty soon.
