I know I can reduce the stream by using the adjustment screw, BUT, if the wrong nozzle is being used to begin with, and you rely too much on the adjustment screw you just wind up with a ridiculous amount of water depositing right at the sprinkler head. It is better to have the appropriate nozzle for the distance you want to shoot, and make minor adjustments with the screw.
So, here's my problem: Most of my distances are in the 16-18 foot range, but when I look at the Hunter Nozzle Selection Chart, the minimum I can find is 22', using the low angle (gray) #4 nozzle, and the chart assumes a PSI of 30...of course, variations in PSI create variations in the distance of the throw.

I am hoping others out there who like to figure this stuff out for themselves, rather than "call the guy", can help me based upon their experiences with TV irrigation, and Hunter equipment.
I'm OK with trial and error, but would like a suggestion for where to start.

thanks in advance.

Rainbird nozzles will fit the hunter popups. There is a larger variety of choices and much cheaper. I changed several on our system due to the issues you are describing.
