I do not have any specific data right off hand but I have built both of these for customers and can tell you that for anything lighter then a 107 gr SMK, the 6-06 AI is just to much of a good thing.
The standard 6-06 will be much better suited for the bullets you want to shoot but even then, for 75 gr pills, its alot of rifle but much more practical then the AI version.
The AI will certainly work but with the lighter bullets you will not see much of a velocity gain over the standard version.
If you wanted to shoot some of the new 115 or 117 gr bullets or some of the custom 120 gr Wildcats when they are available then I would say the 06 AI would be a more practical choice.
Problem with many of the current bullets we have in 6mm is that we are already pushing them past the design limits as far as velocity goes. Choosing barrel rifling design becomes critical as does twist rate to allow the use of the sull potential of these big 6mm rounds.
Now with bullets such as the 95 gr BT there really is no limit to worry about. Only problem with these is that they are pretty light to make these big capacity 6mm rounds perform consistantly. They will work but the heavier the better in these two rounds.
