ok after visiting a few local ranges I now know what is going on with the range balls vs normal balls.
My local range has a net wall about 200-225 yards away, and unless you make solid contact will you come close to touching the wall....
Reason, pratice balls... or limited flight balls at this range. (found out they use to have a sign banning drivers)
I've been to two other longer ranges with fences of about 250 at one and 300 at another.
those to places use super range balls which fly better then the limited flight balls.
I did notice that at either places the short irons are almost the same distance.... within 5-10 yards
but when the big clubs come out of the bag the ball really does matter.
at the 250 yard range i had the pleasure of finding two normal balls in the basket.... I am assuming a fellow golfer who wanted to test out the balls left them behind. Needless to say, for now those balls are lost in the woods at the 250 yard range. I did happen to hit a super range ball that hit a tree solid so those type of pratice balls do fly well (same 250 yard location).
Summary:
Balls market with practice my be limited flight balls. and balls market as super range balls are very close to normal golf balls, but they are still a range ball and even though i didn't get to hit a normal ball at the 300 yard range, i did have a few balls roll up a hill towards the 300 mark.
Club used was R580 XD 9.5 stiff.
Disclaimer: I don't have a range finder and even though the distances where laser marked at the ranges I couldn't verify it. Besides anyone can be a range superstar right
