Who can do it?

Excellent and a good post. But if you do that you dont have a good control. You would have to weigh and measure every ball.

That is why you would need a separate target for the slow speed shooting and one for the fast shooting and compare the groupings on each. This way you get the averages on each, slow and fast without them overlapping.

When done draw a circle around the groupings and find its center, on both the shoot up targets. Find the amount of change form the slow target to the fast one.


Then using the control balls find the difference in fps (with a crono) to get said drop and there is the drop in velocity.( close enough to put up some numbers or get a ruff idea)

I would actually like to know the results of a test like this - Shooting my Invert mini, I always feel like it looses some range when i rapid fire. Assuming it is not the recharge rate of my tank reg ( Ninja ) I would like to know if its really shooting lower FPS or if it is just my imagination.

The fact of the matter of this issue comes down to this:

If your shooting fast enough to out-run the recharge rate of your gun or tank, your shooting too much paint...... Let me know where you play so I can go somewhere else.

O no it will be a surprise. When i gave up my mechanical and begrudgingly joined the electro ranks, i decided to add my accuracy to a three fingered pull. Now i will make everyone pay for resting my beloved mini-mag from my grip and switching me to the wagner power painters.

My smoothest and fastest electro(in my opinion) and the one i use on ramping fields.

If you ask why then you need only remember the urge to strangel the bastard ramping on you and your mechanical marker.

If you cant beat them, join them.

Edit:I dont think this one looses velocity when i rip it unless the lpr is turned down.

When I had a Viking it was pretty consistent chrono-wise when shooting slow, but I never did a high speed chrono check. I did notice if I was hammering on the Viking, that there was some slight reduction in range, so I am guessing even it had some shootdown, while in hose mode. On the other hand I have had good consistency out of Mags and Cockers too, but the thought of doing a control with 68 caliber nylon bearings did not occur to me. It is an interesting idea never the less.

Hmmm. Where are they?

Yup high speed camera with a distance chart for backdrop. Frames per second and elapsed time or built in timer and bingo we got FPS on evey ball.

The only problem i see with this is placement. You would have to ensure that the markers are chronoed to ~300 fps and that they were in the same position when chronoed (i.e. 1 inch overhang if using one of the red type of chronographs) then that the end of the barrels are at teh same distance from the start of the meter. That entails that the mount for the markers needs to be adjustable for back and forth movement. It's doable, but it's something that needs to be considered if you want the test to be worth anything.

Styg also brings up a good point, each and every marker should be used with multiple tanks to see if that is what is causing the inconsistency, or if it is the reg on the marker. It would really just come down (mostly) to the recharge rate of the reg, so that way we could also see what the most consistent regs are.

Give me the FPS on EVERY ball AT ANY BPS.

The red chrono is easy at one BPS.

BPS really dont mean a thing if you dont know the FPS on EVERY ball in that second.

I say there is a drop.[cant prove it yet] If you chrono at 300FPS at one[BPS] I would bet that at ten BPS, FPS would drop and then level off.

I am even tempted to bet that if I chroned an X-Valve at 285 at one BPS then at ten or more BPS FULL AUTO I would be at about 295 CONSISTENTLY for EVERY ball.

I have vid of the EMag at twenty BPS Full auto but no clue at the FPS on every one of those twenty balls

This leads to the question, what is the MOST consistent gun and at what FPS.

I always see the adds.........This gun is so consistent OR extreme consistency. I call shens till someone posts or tells the REAL numbers.

I have or can get everything I need EXCEPT the chrono to read the FPS on anything more then eight BPS.

68 cal. Barrel Bore. Check.
68 cal. Three Gram round nylon balls. Check
Ability to make most guns on the market shoot full auto at a set BPS[not pumps] Check
Device, Chrono or super high speed camera to measure FPS on EVERY ball at high BPS.

I know for a fact that on HPA at one BPS the Classic Valve will shoot plus or minus one FPS

Just as a thought. The PACT timer won't give you every ball on the display, but does give you the high FPS for a string. So, if you were to shoot your mag across one, you would be able to tell if it is, in fact, shooting up like the legend says.....

The PACT timer is not a chronograph at all. It is an acoustic listening device that measures the time between shots. This device is only used to tell how many balls per second a marker is shooting. PACT timers do have the means of recalling an entire shot string, shot for shot, and giving the interval between each shot.
The newest handheld paintball radar chronies can give you the average FPS in a string, but not the FPS of each ball within the string.

Perhaps, then, I am misquoting the device being used. Small handheld that will run FPS, BPS, and show highest and lowest shot in string as well as the last 3 velocity. CFOA has been using it for years, and the GFOA may even have a couple of them, but I have not seen it first hand.

At a calibrated distance you have a sensor at the end of the barrel and one on a target board sensing impact. That way a computer can use the time distance equation for each ball that leaves the barrel. But that is only a measure.

Think we're talking about the same unit. http://www.paintballradar.com This unit does tell you FPS & BPS, is fairly economical and readily available through Kee Action Sports.

After looking into the PACT Timer a little deeper, it seems that the folks at PACT have indeed added a full function chronograph to their Mark IV line. The timers that I bought in 2005 & 2006 for CFOA use did not have the chronograph function. So, you were right.

Beemer, you might take a hard look at the new PACT Timer, the Mark IV XP, it might just be what you're looking for. PACT Timer.

Just make something. It can be a device that fits onto the end of the barrel. Use two pairs of break-beam eyes with a known spacing. Measure the time between each beam for the velocity of the shot. Record each instance triggered by the activation at the first set of eyes. The time between each activation can be recorded as well and will give you the bps.
