I haven't owned a 338 -06 AI, just played with the numbers trying to determine what kind of performance I can squeeze out of a carry gun.
What I like about the 338-06 in general is that it gives excellent accuracy and power in a standard long action and you don't have to go belted to get it like you do with the 338 Winny. It gives about 85% of the performance of the win mag with much less recoil. That caliber is about the perfect North American carry gun IMO. You can shoot ligher 160-185gr class bullets and have a very flat shooting deer and pronghorn gun. With the 225 grainers you can have a great dangerous game or LR big game load.
The AI will add 75-100 fps of velocity to the standard version but still be much lower in recoil when compared to the 338 win mag. Maybe more importantly the AI's are great for giving better case life and barrel life. Admittedly barrel life in a 38 caliber gun like the 338-06 isn't going to be a big issue but I will take every advantage I can get.
If you already have 338-06 cases they are easily formed to AI by simply shooting them in your AI chamber.
