Thanks for the input. I hooked it back up to compressor and filled back to 4000 psi, my Huben gauge on the input (fill) side reads exactly 4000 psi as does my compressor gauge. The 1250 psi is on the regulated side. I bled it all down to about 1k psi, hooked compressor back up and ran it until pressurized and all 3 gauges read 1k psi.

I might try another gauge on the regulated side just to triple check, but it appears all 3 are in sync at varying pressures. Going to fill all way back up today and see how many total shots I get before it equalizes @ 1250 on both sides of the regulator. My math says it should get around 140 full shots before it goes below the regulator @ 1250 psi but we will see.

So that is a technical question. Although I am not a professional tuner but I do tuning for pleasure.

Accuracy is a combination of projectile, barrel, rpm of the projectile and fps.

Now if we keep the projectile and barrel constant, the rest of accuracy depends on fps and effective rpm.

Effective rpm are different from twist rate of barrel.

When a projectile is shot from a barrel, we need to achieve the best combination of fps and rpm of the projectile for extreme accuracy.

The actual phenomenon is the as the projectile moves forward, the rpm do not reduces as rapidly as the fps is reduced.

In order to keep the best combination of fps and rpm of the projectile, we need to maintain the best combination between the both.

If the accuracy is fine at 50 yards it means that rpm and fps combination is fine for that distance. But if you stretch to 100 yards, the rpm does not get slow down with same ratio as the fps slows down. This disturbs the effective combination of rpm and fps as well as accuracy.

That is why in order to achieve the best possible accuracy at any distance, the rpm and fps needs to be maintained for that distance.

One adjustment to achieve this combination is HST.

Adding a regulator to a non regulated rifle normally implies loose of power because there's no calculation of plenum needed.

Buy a FX DRS, an FX Panthera, a Vulcan 7 700 or a Uragan 3.

A big and expensive mistake is to spend to much money in trying making a rifle to give a performance a to which it was not designed for.
