Couldn't you use a ball micrometer?

It's hard to answer questions until the person asking can understand the answers.
I don't think you're talking about bullet jackets, and a measuring tool is a 'caliper' not a 'caliber'.

IF you are measuring only jackets without a bullet core in them, then a ball micrometer is the tool.

IF you are trying to measure the completed bullet diameter (which is what it sounds like), a blade micrometer is a better tool than a caliper. If you are truely finding a .001 to .002 variance, my bet it is more the variance in the tools ability to measure vs actual diameters.

IF you are trying to measure the jacket thickness AFTER a core has been seated, then forget it. Not going to happen with any degree of accuracy.

Thanks everyone,

Just need to know if there's a tool that can measure a complete bullet thickness more accurately than a calipers.. something like a Lee wislon no go gauge

If I read you correctly, you need a base to ogive comparator, these are available from RCBS, Hornady, Wilson and Sinclair. There are also comparators that measure the above and also have attachments to measure bullet length, meplat length and headspace.

If it's bullet diameter you're talking about, then a micrometer that reads to ten thousandths (.0001") is what you need.

Cheers.
