Edit: ah maybe my poor explination, it raises the fps by about 22 so it had to be chrono'd down again.mike from brum said:Sorry to be pedantic but
DEZign bolt (drops fps by 20 so more efficient.)
This would infact make it less efficient so you might want to change it
Ahh if you put it that way, then yes it is more efficient. Maybe word it a bit better and I can delete my postBob said:Realy? If you set it up with the stock bolt then put the DEZign in it shoots hot so just chrono it down. I thought lowering the pressure made it more efficent or have i missed something (has been known to happen )
