If you have the pressure and flow there is mo reason you can't get 40' out of a # 6 nozzle with funny pipe and saddle tees, I do it all the time.

What he said, if you've got 50PSI static, you do not have anywhere near that dynamic. I'd bet your dynamic reading is more like 35PSI or less (just a rough guess). You need to run the math on the hydraulics and figure out what your supply really is or how much you need to increase your pipe sizes.
The funny pipe swing joint isn't the problem.
