No reg experience but hoping...

This Kral .30 I have gets a 24 ES at around 90 PFE (Then drops off considerably half way through mag #3.
I'm not sure if a reg can get me more shots or not.
I've been debating getting a 5L CF tank and a reg that Kral made for the gun, but I have no info on the reg other than they say it's "set" for 185 Bar (2683 psi).
Does anyone (Bob and other smart folks) think I should be even trying to reg this rifle?
I know the ES is pretty good for a larger caliber right not but shot count stinks.
Fill pressure on the standard tank it came with is 250 bar.
Also the reg that is sold for this rifle looks like it have a large plenum tank to block.

I'm getting a .5L cf tank in a few days and the Kral made regulator for this rifle..
I do plan on adding a few hundred lbs over the 250 bar.. maybe 3800 psi.. 262 bar
That should be fine with this setup.
If I can make a ssg for it I will.. The reg is supposed to be set for 185 bar from the factory.. 2683psi..
The plunum looks huge but I have no info yet on cc's.. I plan to do a water test with it prior to install and see exactly what the plunum volume is +the block volume combined..
Is 185 bar normal for a reg on a big bore? I have no idea..

Reg pressure needed will correspond to plenum volume, and barrel length also plays an issue in energy production. Look at FX as an example, their new rifles with larger plenums will produce the same energy or more with lower reg pressures. Barrel length increases available energy level.
