This will ensure you are using your delts, but not putting excess strain on your supraspinatus (a muscle of the rotator cuff).
Secondly, you should lower the dumbells until your hand is level to your shoulder. The most common shoulder injuries arise out of imbalances in strength between the supraspinatus and the deltoid. If you aren't using a full rom your deltoid will hypertrophy and get stronger while your supraspinatus atrophies and grows weaker. This is a recipe for a rotator cuff injury later on in your lifting career.

i agree with the most of this post. but not using full range of motion isnt the cause for muscle imbalance. neglecting the posterior delt, and rotator cuff muscles are the main contributors. however you can do seperate exercises to strengthen them and keep them up to par.
heres my thing. the shoulder is such an unstable joint, why do so many people want to over load it with heavy weight on an over head presses?
also... from a personal training perspective, i would never advise my clients to take the movement as low as possible. when the shoulders are in that position. it leaves them very voulnerable to injury ( it pulls the head of the humerous away from the shoulder complex in an unnatural position). 90 degrees is the the safest bet.
nobody has ever asked my how much i can military press? its not important
