Depends on how thick your gear is !?!?!?!
For me....shooting 1.5 cc's of anything will take a little under 3 minutes of actual injecting time. The slower....the better (within reason).
I hear you Bro, I guess because its the first time I used a 25-1 needle
and that its the first time injecting other then the glut and it's the first of many in about 4 years it also seemed longer
