As a matter of fact, when the 286 Partition was new I got involved with a new bullet-testing medium my friend and fellow gun writer Richard Mann developed, made out of soft wax. Its big advantage was retaining the wound channel, so you could actually see how various bullets expanded (and sometimes didn't), but it also provided a valid comparison of how deeply each penetrated.
Was that the Bullet Test Tube, and, if so, what happened to it? I take it it's not available anymore. It seemed like a great idea.
