What is the problem with using the regulator to chrono our snipers?

First off before I get flamed. I know how to use the IVG and I know about sweet spotting the reg. But I have been thinking about just backing my IVG all the way out and using just my regulator to get to proper velocity. My thinking is that's the MQs do it. DMs, Egos and all the 'others' do it that way. The only difference is they have electronic dwells and our is manual. When Bud Orr designed the Sniper, there was just unregulated co2, the IVG was way to manipulate the spring to get proper velocity instead of swapping springs out.

Let the discussion begin.

Who said there was a problem?
I put my IVG all the way out for a light pump stroke so I have to adjust the FPS with reg.

It's not necessarily terrible, but the reg sweetspot is exactly that. Your valve will usually work best at that setting. I think the most obvious symptom of a person taking their reg way out of line with the sweetspot is valve farting.

The difference between everything you listed and your current gun is the fact that the valve isnt electronic. The air pressure helps the valve spring close the valve. This is why when people never touch the ivg and they keep trying to get the velocity down their gun starts venting after every shot. OR you get the pressure to high and it farts really bad.

Think of adjusting the springs and IVG as adjusting dwell sorta. the further in the ivg goes the longer the valve stays open before the pressure and spring close it. not enough pressure or too light of a valve spring and the valve wont shut or shut very slowly and the gun vents. Too much pressure and then the hammer doesnt open the valve very much and is slammed shut causing the hammer to bounce off of the valve stem.

The problem, if you can call it that, is that the pressure affects the dwell. This causes the gun to have a velocity "bell curve" where there is a peak velocity and above and below that pressure, the velocity is lower. This means that if you are not at the peak of that curve, you are running at less than maximum efficiency. And if you are setting the velocity on the high side of the curve, then as pressure drops (e.g. at the end of the tank), you will see a velocity spike, which could be dangerous.

DrGonzo is right about the High velocity at low air in tank.
I tried to use my Ninja SLP tank sweet spotted reg . can't get under 312 psi.

without changing anything put a tank on 500psi output drop velocity to 247

So, if I am using the regulator to adjust my velocity, I should be starting at the lowest psi settings?

I usually start a 240 PSI ,If you don't have a gauge YES start a low setting .
At the lowest setting the valve will stay open ,Turn the pressure up till is stops
and start from there.
