The seat end for the bottle is a ball pressed into the spool and it does not appear damaged at all as in the pic above. I wonder if it's possible that I unsprung the belleville washers running them up to just under 2500psi on the Ninja spool?

DOUBTFUL ... Regulators and there correct function while simple in basic operation can be screwed up with simple oversight on the basics of what required getting from HP to controlled LP.

** See NO picture of the Spool ends seat ???

I guess it's not very clear in the first pic I put up but you can see there is no visible damage to the ball in this close up. I've replaced O-rings and lubed the washers anywhere from very lightly to more than I would consider enough with the same results on every test. I polished the washers cleaned with brake cleaner and a lens cloth then lubed and reinstalled. It's installed correctly and it's not working for me. I am down to using the hand pump only now so is there any chance I need to shock the reg with a faster pressure increase to get it to act right?

The bevel stack just creates a given SPRING RATE.  Pending how close or far away the actual seat is from end of spool dictates HOW FAR the given bevel springs must compress to get the seat to seal up.   Closer this gap LOWER will be the set point ... Further away HIGHER will be the set point.

Thus the WHY FOR a given spool and bevels in differing bodies have a different set point.

So to be clear, you are saying that if a bonnet applies more force on the piston towards the seat, it has no effect on the pressure output?

I keep running my 90ci Benjamin bottle out without ever shooting a single round. Running to the next town over to get it filled at Scheels is getting old....I think I need a compressor. 8)

I overhauled my hand pump and I've been pumping like mad with that but only up to about 2K. I'm still recovering from a broken elbow from a bicycle wreck on Dec 5.

I see you are sold out of regulators, Should I just see if I can get some better quality Belleville washers and experiment with them and if so where should I get them?

Yeah I am out of regular Ninja regulators and will only be stocking the Pro V2 style from now on. Less SKU's and it's a better reg to boot. Those (Pro V2) I have in stock. Another worthwhile addition to your tools is a test adapter for your regulators so you only wasting a few CC's of air rather than filling your PCP's tank every time.
