Wolfe Publishing put out a huge book on wildcats, one of which was the 30-30 AI. He got 2500 fps in a 20" barrel, but complained of problems with sizing and bullet seating because the 30-30 case was so thin that it frequently buckled in the bullet seating procedure. If you want to give me an address I'll copy and mail you a copy if you can't find one yourself.
Also Fin Agaard tested a Clifton modified Marlin 336 30-30 AIin the American Rifleman some years ago, commented on the loading problems with the thin 30-30 case and opined that the AI was not worth all the trouble for the modest gain in velocity
You should visit the Wolfe publishing web site. Wolf publishes Handloader adn Rifle Magazines, among other things. If you sign up, you can obtain access to all of their past articles on handloading data. I suspect you could obtain the foregoing article on line that way and probably a great deal of other useful information.
Good Luck with your 30-30 AI.
