Fx impact 600mm vs 700mm barrel

Not sure if the Crown makes the same gains but I think most are seeing 35-40 fps per 100mm. My .25 Crown when stock went up 143fps when going from 380mm to 700mm shooting 25.4gr Kings.

Roughly and generally around 10 fps per inch is the expected norm.
100mm = 3.9 inches. This would be in alignment with srtmat's experiences of 35-40.

That 10% is likely with a stock gun so if one can feed it a bit more air it will probly do a bit better than that.
