HELP—UPDATE: FX Wildcat accuracy problems

It sounds like you’re on the right track. One thing I would suggest is to change no more than one variable at a time and write down any changes in a notebook. So if you change the speed and remove o-rings simultaneously, which caused the improvement? Anyway sounds like things are getting better so that’s good. Keep experimenting. And please post result. 

I’m getting very good results with the 600 mm .25 X barrel but I’m also getting some flyers so will be experimenting as well.
