Example code (you will have to change the projectile id to the correct id for your bullet) 
@itemIsUsed
createProjectileAtPosition('hGZYvDoFxn', polarProjection(getEntityPosition(thisEntity), 64, entityFacingAngle(thisEntity) - 1.5708 ), 20, entityFacingAngle(thisEntity))
// (optional) sets the source unit of the bullet
setOwnerUnitOfProjectile(lastCreatedProjectile, thisEntity.owner)
// (optional) sets the source item of the bullet
setSourceItemOfProjectile(lastCreatedProjectile, thisEntity)
createProjectileAtPosition('hGZYvDoFxn', polarProjection(getEntityPosition(thisEntity), 64, entityFacingAngle(thisEntity) + 1.5708 ), 20, entityFacingAngle(thisEntity))
// (optional) sets the source unit of the bullet
setOwnerUnitOfProjectile(lastCreatedProjectile, thisEntity.owner)
// (optional) sets the source item of the bullet
setSourceItemOfProjectile(lastCreatedProjectile, thisEntity)
