Sprinkler nozzle not spraying to listed distances

Thanks for the vote of confidence there wet_boots, could you please elaborate for the amateur did wrong with this calculations? I did the bucket test for GPM at the valve, and also hooked a gauge up to get the PSI from the same valve, which the numbers are stated above. I was also worried that I had run into a flow problem but I turned the system down to 2 spray heads being active with no visible change between that and 6 heads (a flow change from 10.06gpm to 4.74gpm) I don't mean to sound overl...

Sprinkler nozzle not spraying to listed distances

There is a slight slope, maybe 2" drop per 10' but even the one on higher ground going downhill I'm still only seeing just above 9'.

They are not misting or fogging, I can shoot a video if it will help.

Sprinkler nozzle not spraying to listed distances

I am using the Rainbird 1804 SAM series.

Sprinkler nozzle not spraying to listed distances

Hi All, I recently purchased and installed a system, or at least finished one zone so far, I purchased the Rainbird HE-VAN12 nozzles and I seem to be only getting ~9ft not 12ft radius. I checked each of the heads for contaminates, shut off all but 2 heads, and I'm still sitting with only about 9ft of distance. Some more info on the system: At the valves I am getting (Rainbird 100-ASVF): 42psi 15gpm Measured from an adjacent valve. I am using 3/4" sch40 PVC for the laterals, at a maximum distance...
