Not sure how I've never heard of this book, but I saw a new version was recently released and heavily revised. I'm always interested in cartridge reference material and wondering if this would be a good companion piece to something like Cartridges of the World. Does anyone have a copy, and, if so, what do you think?

That sounds like a very interesting addition to one's library. I have COTW, as well as Donnelly';s Cartridge conversion book, + too many to list manuals. This sounds like something that should go into a real reloaders library. I might be able to find it on Amazon, but do you have an ISBN #?

I looked on Amazon, + they have it at $39.95. From what I read on the synopsis for ME, is that it would be redundant for all the books I already have, however, if one does not have a gun/reloading library, +/or is getting into the reloading community, then I think that this book will be a great help.

My interest in it is primarily for the dimensions of some of these wildcat cartridges. COTW lists all the data, but doesn't give any sense of size or dimension with the descriptions. Plus, it's always handy to have a second reference for a cartridge. I might grab a copy when I can. If I do, I'll post here what my actual impressions are.

If that is your primary concern then I will recommend, again, John J. Donnelly's book, "The Hand loaders Manual of cartridge Conversions." That will give you everything you are asking for.
I bought mine 30 years ago for $39.95 + it was some of the best money ever spent. I know you can find it cheaper now. A couple of years ago, Edward Hamilton Booksellers had a new paperback version for $9.95.

I just checked Amazon. Their new copy is $29.95. The old one that I have is now priced at $375.00?! It is a good book, but that is an insane price. Buy the cheap version, but you might want to consider doing it soon.
