It is permitted to borrow someone’s shofar on Rosh Hashanah without asking the owner and say over it the berachos for blowing the shofar. It may well be asked whether under such circumstances, one is limited to the 30 obligatory notes, or may one also blow a further 70 notes which are customarily blown in order to reach the number 100. The answer is 100 – but no more than that! (Mate Efraim 586:5)
