FX FX Impact M3 - I Can't Tune It to Higher Velocities - Strange ???

[greenbeans]

It's a 700mm Superior slug liner.

I'd have thought that most / all FX M3s were the same / similar out of the box. Unless there are lower power ones sold in the UK where I am ? But mine's on a Firearms Certificate, so I assume it's the same as all the other .25 cal M3s out there ?

Just reading the license part… you’re in the UK? Wouldn’t be the first that comes with sub12 mods even though you get it on your ticket. If you’re hammer is maxed and you don’t get to 880 with 130b or more, chances are are you got a sub12 version or some parts/modifications thereof.

There it is. I bet hes got a sub12.

One last think to make sure we’re not missing the obvious here: you did increase the hammer when increasing the pressure, right? Not the macro wheel, the micro adjuster. If not this is the very first thing for you to do. Micro to 5. 170b is probably way to much at this point but you’ll see substantially higher fps than what you get right now.
