    Hi All,

    Just got an Uragan in .25, does anyone have a suggestion for 25.4 jsb velocity? I found my grub screw that secures the power adjuster loose on delivery so when I chrony this bad boy I’d like to set it at an acceptable speed.

    Thanks in advance!



    I don’t like any grub screw going into another threaded Part, do you really think it needs securing? It is not FX :rofl:

    To put it differently, what will happen to the tread of the adjuster when you overtightern that set screw?



    I haven’t posted in years but I did just adjust my Uragan .25 a little.

    It came shooting the 25gr JSB’s very well ay 940 fps. My targets are generally at 50-75-100y and there is usually wind. I was hopping to shoot the 33.95 MKII’s. They tested okay at about 860 fps. I wanted to see what a little more speed would do. Half turn in on the adjuster got me to 890-900. The Kings (25gr) “only” jumped to 960-970. But that was too much for the kings, at least in my gun, groups at 75 went nuts. With the MKII’s, If I miss at75y its my fault. Haven’t done much at 100 yet.

    And if mine had a grub screw… I never even noticed.




    Hi All,

    First off, this gun is definitely not an FX! It’s bananas good…

    The grub screw secures the power adjuster as it’s quite loose.

    I detuned it to 905fps from 940, shooting starlings at 115 metres is lots of fun!



    You can’t go wrong with a Vulcan, I have two and both are awesome shooters.
