Nelson P150 3" fast reverse big guns .97" ring nozzle and repaired brake and reverse arm

finally decided to get my setup out today. a bit windy but still 65F today nice and decently warm. gun worked well and reverse was slower than usual.
According to Nelson's performance charts of the SR150 (pretty much the same gun but slow reverse). With a .97" ring nozzle at 50PSI you get 130GPM and a distance of 265feet. I believe the specs are all the same on the P/F/SR series guns. The only difference is the P is part circle (fast reverse), the F is full circle (pretty much the P series with no reverse or stops) and the SR is slow reverse.
