I thought the point was that other mass-manufactured ammunition would be more likely to contain equally consistent loads that could be 'dialed in' and adjusted for. That said, I don't have a problem with the 'proprietary' ammunition, but gun owners tend to be informed on that kind of purchase. It should be easy to match the load profile and come up with a "Surgeon-compatible" ammunition, should the tech ever catch on to that degree.
