No, but since these are high quality match grade bullets, it’s highly unlikely they are a source any measurable runout. I don’t think the gage can be configured to check the bullet by itself.

I did notice that bullet runout is typically 2x the runout of the case neck. But I think that can be explained by where the runout is measured: at the mid point of the neck along its length and on the bullet approx 1/8 inch forward of the neck. If the axis of the neck is slightly off at an angle relative to the case body axis, then the runout increases the further forward you measure on the cartridge.
