Actually, I have not seen the exact article that you are describing, but there have been a number of articles in Handloader and Rifle within the past year with considerable discussion of the new rifles, and of the older ones. Some have been to contrast one to the other, and other to clarify specific issues or loading data.
In addition there have been several threads here that have provided considerable insight into several aspects of the new rifles, and the old ones at times. You might review those to see if you can find specifics.
