LOL, you are a bit more advanced than me . Though, thanks to a new TP my JSAR M-Rod is right in there on the power and shot count now that it is not wasting a good bit of air out of a leaking TP!!!!!!
To mention something here, JSAR has the aluminum reservoir tubes which knock a lot of weight off of the rifle and improve balance greatly but at a very slight loss of volume. They are suitable for use with a regulator. The AGR can (possibly) custom build a hybrid steel/aluminum tube of greater capacity but the hybrid tubes cannot, repeat, cannot be used with a regulator as the ID is different from stock. My unregulated rifle with standard length hybrid tube gets as many shots at slightly more average power than my regulated JSAR M-Rod. Both need the JSB 34 grains pellets to be in their happy places. The addition of an aluminum tube caps the fill pressure at 3,000 psi, I know folks sneak some extra psi in on the standard steel tube . Best not do that with the aluminum tubes.
I ty to tune at around 5% below peak on the two regulated rifles. That results in a mini-Bell curve once off the reg and those are still useful shots off the reg.
Curious, what is your regulator pressure? I may need to toy with that again?
My regged gun is aluminum tube made before Jsar entered the game.
Fwiw, you've been mislead about the marauder aluminum tube max fill pressure. They can safely handle 3250 psi fills. The individual that tested these tubes to failure used the wrong calculation to determine the safe max fill pressure...and I can extensively prove this here, and have to him, he had no words...and he is more than welcome to enter this discussion or any with me civilly.
"The ASME Code provides maximum allowable stress values used in calculating a vessel’s wall thickness, which vary with temperature. In Division 1, governing design by Rules with a safety factor of 3.5, a 60,000 psi tensile strength material has a Maximum Allowable Stress Value of 17,142 psi. In Division 2, governing design by Analysis with a lower safety factor of 2.5, the same material’s maximum allowable stress becomes 24,000 psi.
Some companies insist on Division 2 standards for their pressure vessels due to more rigorous requirements, while others may opt for Division 1 or Division 2 based on cost considerations. Typically, manufacturers choose Division 1 for low-pressure vessels and Division 2 for high-pressure ones. The maximum allowable stress values for commonly used steel plates in pressure vessel fabrication are provided in the table for the normal temperature range."
I personally use a SF of 3, in between Div l and Div ll because airgun tanks are high pressure vessels.
