I have been looking for 8mm bore and thoat erosion gauges everywhere and can not find anything. Do they exist?
I have been using 8mm rounds as a guide to the muzzle wear but I would like something more precise.

A throat gage is only useful between barrels if they were made to the same bore and groove dimensions and.... the barrels were throated to the same spec. The tool may not "tell" you much of anything at all when used on a variety of 8mm rifles.
what it can tell you quite well is how much wear is on the barrel since the last time you gaged it.
