shot put regulations

[discus108]

ok so i have been doing shot put and discus since 6th grade(currently in 8th) and during shot put they have always counted it a scratch if the shot was not touching skin(meaning neck or cheek) the whole time untill release untill this year where it seems that nobody is touching skin.... Does anybody know the official ruling for it? ps if i could have the info by wednesday the 16 that would be very helpful being that the 16th is districts

thank you
