Waht is the best book on the AI cartridges that contains forming, loads, etc? Thanks.

Ackley's own manual, two volume set. Was reprinted a few years ago. Check around, maybe EBay. You won't believe how LITTLE is truly "new".

Ackley's "Handbook For Shooters and Reloaders". It is listed in the Sinclair catalog. It is a two volume set, and the most interesting discussion of ballistics I have read.

i just bought the SIERRA #5 manual. it has several of the ackley cartridges. it is the first that i have seen since the speer #3. interestingly , the loads that i developed for my 250AI are right in line.
GOOD LUCK and GOOD SHOOTING!!

There's a big book of article reprints from "Rifle" and "Handloader" magazines that is all about wildcats...some with multiple articles on the same cartridge. If you like wildcats it's a must have...can't think of the title right now but it's the size of a phone book.

It's from Wolfe Publishing Company, same ones who put out Rifle and Handloader. I got the combo edition: Wildcat Cartridges Volume I and II. Near as I can count it's 1,050 pages! Wonderful reading although a bit dated as it was published in 1992.

As stated. it doesn't get much better than the reprint of the book by the old master himself. I think he wrote it in the early sixties.Some very interesting observations, especially on his testing of the strength of various military rifles using duplex loads.
