If this information is accurate it would disprove the claim that the Carcano was the only rifle with a .268 groove diameter.
Michael, I'm not sure if you're following the arguments.

Read the thread "Carcano Rifles". You will have a much better understanding of what is going on. The article I quoted is written by Dave Emary, who is the Chief Ballistic Scientist at Hornady Mfg. As the article reveals, Mr. Emary feels strongly that the accuracy of the Carcano rifles suffered shooting bullets that were .264" in diameter, such as those made by the Western Cartridge Company, and the situation was not rectified until Hornady began making .268" diameter bullets (.2675", to be precise) in 2002.
I know that everyone on these forums continually demands that our sources be qualified or certified or licenced. If the chief ballistic scientist of a major ammunition manufacturing company does not qualify in your eyes, I don't know what else I can do.
Hornady; the company to whom you referred only a few posts previously to as being 'disinfo' agents are now your preferred ballistic experts.
I would also raise a not insignifiant point; that being, do you actually have evidence that the WCC ammo used a .264" bullet? I'm not aware that you have produced any evidence to that effect. You do not own any of this ammunition so are not qualified to comment. In fact, the ONLY reference to it that I can recall on this thread is a link to an ammunition collectors discussion board where a chap who has actually measured some says that they have a .266" bullet.
