On my own site I always open a PDF in a new window/tab but always have a note beside the link saying what will happen.

I overused _blank in my less experienced days and still come across annoying little things as a result, such as the page that didn't have any navigation as my original, and forgotten, intention had been to display it as a stand alone item in a new window.
