Tm pistol fps issue

[Mrjackyoung]

Recently installed a nine ball 6.00 barrel in my fn 5-7 and a a-plus hop rubber and im getting around 260 fps with a 0.25 the gun is about two years old what could be giving me low fps ?

Thats about right. ~300fps on a .2, remember if you up the weight of the BB the FPS will drop but Joules (energy) stays the same.

Hows it feel to be given the all clear? It was ok all along, what a relief.

Also, 6.00 may well decrease it!
