I have the book. I would say this:.. If you have all the others like Taylors, Mckintosh, Keiths or Boddingtons(1+2) Wielands book is just a waist of money. You can ofcouse do what I have done..add a book to your library, and have another author represent his views.
Everybody likes to write about " DG rifles", but really it all summes up around a Mauser M98 anyway so if you do not have Jon Speeds books, get them instead
