Hello guys,
this is my second time starting this season that my revere after filling up is shwoing Strange gradual increase of power and then stays there for some time!!!
this revere was set around 850fps for 10.34gr,
and I m using 10.03 barra heavy domed…
but i never experienced this strange regulator behavior before???
anyone wanna shine in on this strange behavior of my revere .177
i was also thinking it could be the weather as we are entering summer slash spring temps here in north east…
here some latest chrono chart for understanding what’s going on With this rifle.

Just guessing, but could be that there’s not enough hammer. While bottle pressure gets lower and closer to reg pressure, reg might give a few bar less and speed increases until you fall of reg entirely and shoot lower. Should not give you such a slow increase over so many shots though… and that’s a loooot of shots, all of them from one fill?! no idea how much you should get out of a revere at that time though, are you shooting it below reg pressure? Most regs don’t like that…

Just questions for now
By 245BAR I assume you mean fill pressure
What is the reg set at?
As the tank pressure drops, does the reg pressure remain steady?
If not, does the reg gauge creep up, or follow the tank pressure down?
Suggestion
Run another full string noting not only fps but also note the reg gauge reading every 10 shots or so.
Maybe you will see a pattern
And of course, let us know the results

just my 2BAR

If another rifle is showing a similar pattern, I’d check the chrony and my setup. What make/model are you using?

Good idea.
i m using Orcair chronograph….
i compared it with my dlx pro chrono and it was only 5fps away from each other for like good amount of shots that i tried.

Yeah 245 bar means the rifle is full to this pressure at the tank,
the reg by factory is set at 150bar.
didn’t check it since I started this season but it was last time I remember. but I will check again…

When was the last time this gun received a rebuild? New orings and deep cleaning can really help with many issues

I bought this revere last May of 2024 From Aoa.
it was working fine before Storing it for the winter.
strange thing is
my drs is also behaving the same way…
gradual increase to the set regulator pressure and then floats there till I drop enough shots for the air tank to go down…
