Western Airguns Rattler .357

You really run things to their max . Have you managed to break the 270 fpe specified upper end? If I recall you ran your plenum pressure really high as well…

Probably, I set the reg to 225bar and it was getting about 6 shots before falling off the reg. It seemed really hard on it and I want a full mag so I didnt chrono before switching back. Kinda regret it out of curiousity but on about 170 bar i get 240fpe with 174g high arcs at about 790fps. Thats plenty and accurate!

Hi,

I received my new rattler today, the regulator was factory set at 140 bar and I could send 125-grain slugs at a maximum of 850 fps.
i wanted to increase the regulator a bit, but when I turn clockwise the regulator pressure drops.

Have you ever had this problem?

EDIT: Problem solved, I turned the wrong way, the instructions are really poorly explained.

Do you know if there have been any changes/update since the rattler came out ? (except the silencer, which now makes too much noise)

I've listed the batch i've seen on youtube
