My youngest son gave me a $100 gift card for use at one of the local big chain sporting goods stores as a Christmas gift. I picked up a bag of .338 WM brass but was most excited about buying the latest version of the Speer and Sierra loading manuals. Most of my other manuals are fairly updated but these two are old and tattered. Of course, both manuals were covered in cellophane wrapping so I was unable to check the contents of the Speer book - the Sierra book had the contents listed on the back cover. When I got home I was really surprised that the new Speer manual didn't have data for the AI loads. What's with that and do any of you have comments on where to get good data for the Ackley Improved loads?

I thought the AIs were no longer considered wildcats.
