It is, yeah I'm currently experience a similar feedback loop myself.
Hypothesis - Destroy - Learn - Fix - Hypothesis 2.0 - Learn -
Hopefully I continue to hurdle the inevitable Destroy portion of DIY RnD.
The regs I purchased were 2 cheap-0 generics.
The adjustable one I found to be quite...
My buddy has a Jet-II and it's hella accurate and smooth as butter..
Maybe you got sand in it, since you had the sandpaper action problem with 2 different guns?
Could be user error.
The only problem I see with it after several years and tens of thousands of pellets slung through it is the hand...
You only get a single *Well placed* shot.
You can still get several follow up hits on a moving target with full and semi auto platforms.
Is it ethical?
If you don't intend on killing something you probably shouldn't shoot it to begin with, and more hits = more potential you will succeed if...
Me either, I actually already blew the internal seals on my Sig Virtus previously while ummm, tinkering.
Kinda like a chimp just pulling buttons and pushing levers..
Not trying to do that again TBH..
Now at least I got a method to test out PSI BEFORE I blow a new breathing hole somewhere...
In my case the stock regulator isn't intended for modding although it is possible..
It's good, I got a regulator check gauge so I'll just have to mess around with it I guess..
At least until my new regulator that is pre-set at 1,200 PSI arrives
So do you ADD or SUBTRACT Belleville washers to increase PSI?
Let's say hypothetically I thought the rifle could take an additional say, 150 PSI.
How many washers would I need to add or subtract?
I do have an on/off HPA Check gauge, so I will of course ensure that I haven't surpassed the max...
