twist rate 1910 c96

Can anyone tell me the twist rate of a c96 Mauser made in 1910 (4 grooves).

Made a mistake. Can a moderator move this thread to "off topic and other firearms" please.

Lyman's 45th Edition Reloading Handbook reads "Mauser Military; 5 1/2" barrel; 1 in 8" Twist"...That's the 7.63/30 cal barrel...

What I still don't know if that twist rate is for C96s made after 1912 or for the earlier ones.

Pistols Of the World by Ian Hogg details the changes in the "C96" including the pitch of the rifling, but it uses a standard that I'm not familiar with...

Quote - "About 1903...the pitch of rifling was changed from the earlier 1/26 calibres to 1/18 in an endeavor to assure better stability"...And - "...Next major change...came in 1912...barrel...was now rifled with six grooves instead of four and with a twist of 1/25"...

I don't know the context of twist being measured in 'calibres'...Hogg was English, it may be an English rifling/twist measurement...

Hmmmm...From the Encyclopedia Britannica -

"The number of calibres is determined by dividing the length of the bore (from muzzle to breech face) by the bore diameter." I'll leave it to you to figure that out...

Great! now I now that the 1 in 8" is the twist rate between 1896 and 1903.

26 calibers x .308 = 8

And my 1910 C96 should be 1 in 5,5.

Caliber is always the bore diameter. The encyclopedia definition is correct but backwards from common usage. Example: my old ship had a 5" 38 caliber gun meaning the bore was 5" and the barrel length was 5" x 38. As I understand the information from Hogg, the fraction 1/26 means that the length of twist was 26 times the bore diameter.
