Be cool to look at. Another interesting thought is this:
You can get a quick idea with scotch tape on the back of the case. If a factory shell will close with no resistance with the tape the chamber may be over. Conversely if the bolt wont close at all it may be an indication its under size. I wouldnt start grinding on anything without real measurements but it would be neat to see what it does.
Not totally scientific but Ive screwed together a few that way.
