You may want to avoid this. You're doing a barbell front raise, but adding in a ballistic motion with your "explosive" aspect.
The front raise is basically a body builder isolation exercise, and with all shoulder activities you want to adhere to strict form given the ease of injury.
If you want to get a bar over your head, learn the (quite complicated) snatch. With the snatch, the force to get the bar overhead is via the legs and hips, the arms are simply there to act as ropes at the bottom and support struts at the top. Any "lifting" with your arms is bad, as you'll never be able to lift with your arms what you can explode with your hips and legs.
If you want to exercise your shoulders, I highly recommend the seems-easy-but-it's-not barbell overhead press. This is a very difficult lift which humbles even the strongest people. It's also terrific for shoulder development.
