The 1903 - 1905 built at Orberndorf Germany Turkish Mausers were made in 7.65x53mm, and converted to 8x57mm in ~1934 by cut and brazing the magazine box and putting a notch in large ring. The lug abutments have been undermined to shorten the feed ramp.
So they modified a gun built for a 2.992" cartridge to fit a 3.25" cartridge.
The K.Kale Turkish Masers were made ~ 1938 as 8x57mm to start.
These were built to fit a 3.25" cartridge.
A 6.5-06 is a 3.34" cartridge.
You may be able to stretch the K.Kale Turk to work, but the 1903 Turk has already been stretched.
In this pic there is a K.Kale Turk I have sporterized on top and a 1903 Turk I have sporterized on the bottom.
Can you see how the 1903 is shorter?
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?
