The regular spring bore gauges that Caroline suggested is what I'd suggest too.

Yes, this is a standard method, usually measuring the bore gauge with a micrometer, which is extremely accurate. Machinists often use this for things that are far more critical than the bore of a clarinet.

>> Don't go for too much precision - one of my guages measures to 0.0001" - but then you start measuring the grain pattern in the bore <<

If I understand, inch vernier calipers are pretty accurate to 0.001"? Metric vernier calipers are usually only to 0.1mm (you can roughly estimate to closest 0.05mm sort of). So I prefer a digital or dial calipers. I have micrometers that measure accurately to 0.001mm (a micron) but I've never used that for clarinets and I'm wondering if it's even possible, if the material is not too soft for that.
