Yep, that's pretty common. You'll find they're loose and need readjusted. You may need to do this 1 or 2 times before the shoes take their new shape. What's happening is the high spots are being removed from the shoes surfaces and reshaping them to the arc of the drum. The shape of new shoes is just an approximation of what arc they will encounter on new drums(or old drums for that matter). It's important to keep retightening them while they reshape themselves. Doing so improves the surface contact, which provides better braking and allows the shoes to wear correctly.
