I say that because of the drive I hit on the range yesterday, with a used range ball, that went 332 yards if it went an inch, because I was able to actually laser measure it when it stopped.
I mention all the time that there are mounds at the back of the range guarding the Par 3 course beyond it and, depending on how close you are to the back limits of the range tee deck, can be up to 350 yards distant.
