American Rifleman ran an article about the chambering many years ago. Being young and gullible I had an 06 rechambered to the improved version. Some time later I concluded that it was a definite mistake. Little increase in velocity without an increase in pressure, inconvenience, no noticable benefit in accuracy or in killing animals. The only upside I can see is that it provides shooters a chance to experiment and discuss the chambering with other loonies, and, of course, that is not a small benefit.
