Looking at the Quick Turbo Nozzles that have the adapter to go to the richway type body.  Smallest nozzle is the VS15 and I'm running on 40" spacing.  I'm trying to run 15gal acre for burndown but looks like to be at this point you have to be at about 10psi.  Not sure that is enough for doing burndown or is it?

I wondered if they made a cap that you could put a smaller nozzle in or if you did this before with the 15 size just go?

Also like to find a used set of VS20 and 30 nozzles if anybody has any different sizes around they want to get rid of.  Need 22 for 30 gal per acre.
