One for the Gurus

I currently have an FX Impact with a 600mm barrel shooting 25.3G pellets.
If I was to swap it out for a 700mm and use a dual flow transfer port set on the slug port, would there be much of an increase in power. Can always PM if you think it might infringe upon any rules

Cheers

Usually get about 40 FPS gain per 100mm of Extra barrel length and the dual transfer port on the slug side will probably give the same, dependent on tune IE reg pressure and the like, hope this helps.
