Unless bore diameter is really off, you'd need a specialty ID micrometer with knife-edge blades to measure the bore dia accurately from the muzzle. The OD of a lead slug, on the other hand can be measured accurately with your standard caliper you use for reloading. I have some 115gr .311 diameter cast bullets. I'd be willing to send you a couple...
I've thought that shooting a fairly long jacketed bullet with a reduced load into a series of water jugs would allow someone to evaluate the engraving on the recovered bullet to see how well it matches the bore. I haven't done this.
