.673 is quite common around here...
I don't run an insert kit most of the time and don't find I have consistency issues. I can't agree that that's your problem unless your using them as a detent (sorry Bassdude.) More often its simple things like:
-partial rollouts (these can be solved with detent rings, detent mod and to some degree freak, ifit inserts)
-variation in ambient temperature
-all or some of the above
An hpa tank is a massive upgrade in the consistency area but really only solves the temperature variation issue (that can be a big one though, it is here in the Pacific northwest)
