Who can do it?

Holy crap.........reread the thread and some of my grammer:} sucks. Oh well.

But wait here it is. For realz???

FPS on EVERY ball UP to 15BPS.

http://www.virtuepaintball.com/index.cfm?fuseaction=catalog.prodInfo&productID=652&categoryID=192

So I used my 3.5Grams[no wimpy 3G balls here] 68cal nylon BALLS with my 68cal barrel and my Mag.

Two strings of fifteen BPS [auto] Plus minus 1 chronoed at 300FPS. Avg 299FPS.

So the question is...........what is the most consistent gun at ROF. Or should I up THAT thread I started too.

[BigEvil]

I would bet good money it would not be a mag, at least not the most consistent. I would bet that the FPS and consistency would actually IMPROVE the faster it fired though...

Alright Beemer - now all you have to do is start testing every gun out there, and post the results. if you don't have a particular gun, have someone send one to you. Might I suggest you start with something SP...?

Didnt TK do this with an R/T and the WDP Angel????

RT is probably not the most consistent. The AIR/classic valve is more consistent than the RT.

Most of the time when we measure the consistency of the gun, we are in fact measuring the consistency of the regulator feeding it.

There are flow chart diagrams Tom made that would prove otherwise.

Im looking for them now.

In reality, no one cares about the consistency of the gun past the shots per tank by shots leaving the barrel.

Asking a player "how efficient is your guns internal regulator" at the field is going to give you an "i have no clue" answer back.

Ask the same player "how many shots per tank, per hopper do you get" question will give you an either opinionated or factual answer back.

This has nothing to do with consistency though. What you are quoting has to do with efficiency which is a different topic.

Velocity consistency is directly related to the consistency of the pressure in the firing chamber. This is directly related to how well the last regulator in the line maintains a consistent shot to shot pressure.

I don't see why an RT valve, in reactive trigger mode, wouldn't be as consistent as anything else. It's practically oscillating with small end-collisions. You would be looking a variations in temperatures, finger pressure, and oil usage. The first few shots may be off a little as it gets up to speed, but if you need 15 balls, you don't need them all in the same spot.

With a RT valve, there is built-in delay from where the air enters to where the regulation takes place through air passages from the chamber to the piston. In an AIR valve, the air enters through the regulator directly at the point of feedback. The retro valve will never be as good as the AIR valve because of this, although it can come close, and it can forgive other manual issues that some users may have with AIR valves.

Even though the retro valve is very fast at recharging, any variation in any parameters, would cause an amplified effect on the pressure regulation. Theoretically, if the valve is controlled by a computer operated device, then this should not be an issue and it should be just as consistent as any other mag valve once the valve has reached its equilibrium for heat dissipation due to rapid air charging. But, for normal shot to shot consistency, I consider the heating/velocity increase as an inconsistency because the velocity varies depending on the rate of fire. Does that affect my choice of valves? Nope, I use my manual retro mag more than my AIR valved mag, because it is pretty darned close to perfect even with the inconsistency.

[Spider-TW]

I wouldn't consider any transport delays as a source of inconsistency necessarily, just an opportunity for it.

Sometimes I think we focus a little too much on the temperature effects in the RT valves just because TK documented it well. Other designs are not immune to temperature effects, they just don't show up visibly and haven't been documented.

I admit that the more efficient the design, the less temperature variations it should have. I know my Rainmaker gets pretty cold as I dump a bottle of air through it, as an extreme example.

I guess I'm thinking that if you recorded a really good (or bad) string of 15 bps velocities in one second, will that prove anything more about a marker? I can probably get a good one second out of the Rainmaker at some point. I know I can get about four minutes out of an RT mag with at least fair consistency.

Closest thing to get your reading I would say, with out a high tech recording device.

Missed post #31 I was kinda wondering why no one had said it already, np.

That's a neat machine.

Pricey but I think totally worth it..

EBAY...

There is some irrelevancy to what guns can be consistent at high bps cause of the bolt cycle frequency. We all know that hoppers which claim 20bps feed rate wont ever feed that fast, well this is a symptom of what I mean:

The bolt cycle frequency is important because the time the bolt is loitering blocking the breach which pushing the ball down the barrel, it is taking up valuable feeding time. WARPIG did a feed rate test of many guns several years ago, and the automag X valve came up the fastest bolt frequency (despite the lvl10 bolt not going full speed at the start!)

Unfortunately this has always been the other half to having a fast feeding hopper, but no one has every caught on to this fact.

Anyway sure some guns out there might be consistent at 20+ bps but good luck feeding some of those guns consistently. With all the hype of worthless features such as gun weight, im sure bolt cycle frequencies between high end markers will vary from good to poor.
