suggested using a wooden dowel down the bore to gently work the bullet back and forth

Wooden dowels that small in diameter tend to "not be straight" (that's an understatement)
I use a cleaning rod with a
flat tipped jag (or whatever closes the thread hole) to
work the bullet back and forth
very gently so it
juuuust kisses the lands, and
then take a reading. (If you actually press into the lands to any degree, readings can
vary wildly). The right feel is an art, but you pick it up quickly.
I do 5 bullets 3-5 times each and take an average across the lot. Usually that gives me
a number ± 2-thou or so -- more than accurate enough. (Don't get too anal.)
