Thank you Jeff, I really appreciate that. It probably doesn't need saying, but this has obviously been a lifelong passion of mine. It's one of those perfect "engineering geek" hobbies from the purely mechanical and physical perspective. Add to that my love of hunting, and my inherently competitive nature, and I have two ready outlets that provide all the excuses I need to continue to pursue this. It's been a lot of fun for me.

Thanks for the clarification, Joe. The classifications do make sense, regardless whether they are "officially" adopted. The .45 Colt is unique in that it is chambered in such a broad variety of firearms with such widely differing safe limits. About the only cartridge I can think of that has a similarly broad range of firearms in which it is chambered is the old .45-70. Interestingly, they hail from the same year, being adopted by the Army all but simultaneously. And both remain, 150 years later, eminently useful in all of their guises, and remain shooters' favorites as well.
