hey guys - I posted up a little article here
WGP SNIPER 2 PIECY PART FAQS

that has a bit of info on Sniper II's - comments and suggestions welcome.

Also: a few guys ask me from time to time for the Cocker Dating article I posted a while back -- I moved it to Section8's website here:

Autococker Dating

comments, suggestions and contributions welcome.

pretty cool, and btw there is an evolution a\c body on ebay atm

yup - vert feed = yuckypoopoo..

WGP SNIPER 2 PIECY PART FAQS

updated 4.20.07 to include more pump kit info and bolt stuff.

Thump,

Just in case anyone is interested, WGP has a limited amount of Outkast Sniper II's like the one I got available. If anyone is interested and wants one, get their dealer to call WGP. If you don't have a dealer, PM me. I am not sure if they still have a big selection, but if someone is really interested, let me know.

BTW, GREAT FAQ!

Outstanding piecy parts faq! I do have one comment...

DO NOT PURCHASE ANYTHING FROM WHITEWOLF!!!!!

They have a $100 of my money from September of 2005 (purchased premium sniper kit) and have yet to receive the item so they have made it to my PEACE OF SHIT category...

I have done everything to contact and get it resolved. I even send him a yearly reminder..

I have all email / paypal complaints to back it up!

Woody had same problem. FLAKE ALERT!

I found this quote from Bud Orr in 1987

"In fact, boosting the power to unsafe velocities guarantees that your balls are going to fly crooked. I've found that the key to precision performance is to slow the down the ball and lengthen the barrel until you reach the point where the paintball is decellerating as it leaves the bore. This way, it will have a chance to reshape itself into a sphere after the initial burst of C02 deforms it, but before it exits the barrel. And if the ball is round when it leaves the barrel, it will fly much straighter."

-----------

Adding my 2 cents to this, there is a destinct correlation between pressure (e.g. acceleration) , barrel length and performance.

---------

experimenting some Ive found:

the higher the pressure, use a shorter barrel
the lower the pressure, the longer the barrel

---------

Im my mind, the following relationship max out performance (assuming quality bore-sized paint)

pressure ---- barrel length
350psi = 12" heavily ported
< 350psi = 14" moderately ported
>400psi = 10" heavily ported

16" : a waste, except for pushing around bunkers and lowering sound signature.

---------

In the hold the pump handle .vs. dont hold the pump handle discussion,
I know "dont hold" means less deformation earlier - but Bud's comments make me wonder if adding an inch of barrel and "HOLDING" would have a similar effect.

--------

I've looked really close that the hold-no hold issue. My gun, or I should say, my "bolt train", for lack of a better term, definitely kicks back when I fire a ball. It appears that the air burst when the valve releases is enough to kick the bolt and block back a bit. This, in turn, pulls the pump arm and the handle. It's not much, but enough to rock the gun.

This is probably elementary, but thoughts?

Also, I've really had great results from my 16" Freak/AA combo. I noticed a definite and positive difference in accuracy. A little less improvement in distance...

I'll experiment with your pressure/length factors. Thanks!

Dont hold the pump handle for a shot or two and you will see a the most peculiar behavior out around 120 ft - the ball goes a bit straighter than expected - and it stays on track until all momentum is lost.


Grendel Adds:
...there is something that happens when you do not hold the pump handle when firing a Sniper that causes velocity to be higher.

I've verified this rise in velocity many, many times and pretty much anyone who uses a Sniper regularly already knows this. I'll typically get 3-5fps higher readings at the chrono when not holding the pump vs holding the pump forward. I do not know what causes this but do have a theory:

My Theory
When you hold the pump forward all the air used to propel the paint ball is forced against the paintball causing is to be slightly deformed [pushed in] making the ball larger in diameter. This then causes more contact area and pressure to the inner surface of barrel and consequently more friction as the ball travels down the barrel until it relaxes. This increase in friction wastes some of the energy imparted to the ball causing a decrease in velocity as it departs barrel.

When you do not hold the pump forward and fire the gun some of the force of the air pushes the bolt and block back [recoil] decreasing the force being placed on ball decreasing how much the ball is deformed therefore decreasing contact area and pressure between the ball and the inner surface of the barrel and consequently less friction between the ball and barrel. This decrease in friction, in relationship to not holding the pump handle forward, causes an increase to the velocity of the ball leaving the barrel.

Given if this theory is true does the ball leaving the barrel of a sniper where you do not hold the pump forward not only leave the barrel slightly faster but also more round [less deformed]. If that is the case then the ball should fly a little further and be more stable in it's flight path.

Now as everyone knows increased velocity is not necessarily increased accuracy but does allow the ball to travel further and a more round ball travels truer then a mishapened ball.

btw: It was Claydirt that demonstrated this to me off the back of his porch at his apartment off Broad River Rd.. In Columbia in 1994 -- Ive been playing a Sniper II ever since.
