The AI type chamber is added in order to increase powder capacity and velocity.
The main advantage to the AI shoulder is Brass life. The fact that they seem to be more accurate
is probably because they are custom chambers done by a Gun Smith instead of the factory has more to do with with the accuracy.
There is one issue that sometimes is a problem and that is feeding. The use of center feeding
normally solves this as it does in the WSMs and SAUMs.
I for one like the AIs, but do you need it for an already accurate and very fast cartrige like the
22-250 your guess is as good as mine.
