Would any of you know if the moon clip ready shells are equivalent of standard of powered down shells? Or maybe something in between. What is their FPS output?
I am replying to my own question hoping that someone else will find this information useful.
According to my conversation with guys from PatrolBase the MoonClip ready shells are "full bore" - the gas inlet hole at the bottom of the shell is much bigger then the pinhole at the bottom of powered down shells.
This seems to be true also watching this video (this guy is using moonclips):
As an add-on tip I have been given was: if you drill powered shell bottom with 0.8mm drill bit you should imcrease FPS to 320-340 fps. Haven't try it yet but may give it a go later.
