Rattler 357 reg increasing on it's own?

[JumpnJak]

I've had my Rattler 357 for about 2 wks now. I've been generally very pleased with the consistency and accuracy. When I received it the reg was at 140 and has stayed there until today. I noticed it was at 150 this am, took 2 shots, noticed a big jump in recoil and subsequent increase in fpe. Now it's at 165. Any of you guys dealt with this?

A gradual upward migration is usually caused by wear on the regulator’s valve seat (the small end of the piston).

A more sudden increase may be the result of a small bit of debris pinched into the valve seat.

If it were to continue climbing and reach reservoir pressure, it’s probably the seal on the pressure adjustment screw.

Holding at 160 which is what AOA said is the recommended setting.
