Getting 30-06 to feed from a VZ24 is a small task compared to welding the bolt and drilling and tapping the receiver, provided one buys an after market magazine box.
i have milled out magazine boxes, and I have bought them, and buying is better.
To me, Mauser sporterizing is clear in the Walsh book with specific dimensions to change the magazine box and feed lips, it is scatter brained in the Kuhnhausen book. I have been sporterizing Mausers for 47 years and will do another one in a week.
The word 'forum" does not mean "not criticizing books."
"Ad hominem fallacy" is not the same as point by point criticism of books. If you bought the book, and believe it all, it may FEEL like an ad hominem attack, but you might strive to accept other points of view may exist.
Are we a nation of competing ideas, or a nation of forced conformity of thought?
