I sitll get depressed thinking about the three boxes of 5mm Remington I left on the top of my car at the end of a squirrel hunt. Buy 5.000 rounds of the poison of your choice. If it becomes a collectors item, you will make a mint, and, if not, you're set for a whole lot of shooting. As I recall, the 5mm was only chambered for a couple of Remingtons and TC had a Contender barrel. Also, there was only one loading and it was a pure varmint round. The situation is totally different with the HMR, at least.
