Which M5 are you using? For distance you need the 7-12. If you want a little more pressure,go down one, but you’ll get a little less distance and more mist at full open, but great for doing steps or anywhere you need a little more pressure.
I don’t think I’m getting anywhere near 1800 psi with mine at end of hose, probably few hundred. Will try to remember to check it tomorrow.
Something may be wrong with your gauge. At 1800 psi doubt you would even pull soap. They’re low pressure nozzles.
I think I have it figured out, maybe. AFTER opening my throttle all the way on my Kohler 26.5 with General TFSF 2021 pump, spraying horizontally across a parking lot with the M5 rated for 8gpm getting about 35’ @ 300 psi
With the Assassin Nozzle rated a 4 gpm getting about 45’@ 1800 psi but its a misty pattern. Thoughts and suggestions please.

Thank you so much that video was a big help. I’m new here if you don’t mind me asking what is the red tape that you’re using?
That sounds about right now. Either do like William suggested or go on Fb and look for Guy Blackmon shooter tip and order his. What most of us use.
