doublegunshop.com - home Forums General Discussion DoubleGun BBS @ doublegunshop.com (OT) 6,2mm/52 marked old German double

ejsxs,
Yes, I will have it registered as 6,5x52R, which it certainly is, despite a slightly peculiar marking. In fact it was currently registered as 6,5x52R in Germany where I bought it, but our registration office was uneasy due to 6,2mm marking, and demanded a written explanation. Hence, my question here.
With kind regards,
Jani

“The Rifle Book” – Jack O’Connor – 1964 from page 21:

“Now let us see how cartridges are named. The first method of naming cartridges was to give the bore diameter in hundredths of an inch, followed by the capacity of the case in grains of black powder – information that was worth something at the time because black-powder cartridges were filled to the base of the bullet with powder. Examples of this type of nomenclature are the .45/70, .38/55, .45/90, and .50/100. When the first smokeless-powder cartridges came along, the same system was followed for the earlier ones - .30/30, .30/40, .25/35, and others. Often in black-powder days the weight of the bullet was tacked on after the bore diameter and powder capacity, as in .45/70/405 and .38/72/275. Occasionally the length of the case was given as well, such as the .45 Sharps, 3 ¼ in.”

Jani:

I don't think the proofhouse could have gotten all the stamps correct as they had to make at least 1 mistake and you might well have it???

Raimey,

posted the initials. I wish I had a German proof house code of markings to be more helpful. This drilling has a patented self-opener system described in DGJ Vol. 4, Issue 3, pp.59-70.

ejsxs:

Thanks for the effort and I'll read the DGJ ref. I hope within my lifetime that some is able to compose such a list based on the work of Mr. Apel at GGCA( http://www.germanguns.com ), Jim Cate and whoever found the Sauer serial number lists and the Museum in Suhl.


For now I would assume that Jani's 6.5X52R may be a pre-standardization example if prior to 1920. If undated, it may date to pre-WWI and the 6.2mm would be akin to the previous bore stamp lower in diameter than the 172,28, 181,00 or 184,11. For now I don't know if 6.2/6.5mm had a decimal equiv. that was used.

Jani:

I've perused thru my info on target arms and sometime between 1921 & 1924, probably very near September, 1923 date for Suhl's beginning of date stamping, one starts to see a pre-rifling diameter like 7.6mm/46, 7.7mm/46 & 7.8mm/46 for the 8.15X46R. From 1912 on till the inclusion of the length, the diameter stamp only is usually seen. I assume most went thru the Zella-Mehlis facility but Suhl would have had just as high of a probablility. I do have a very tight chambered 8.15X46R target arm with the "181" bore stamp.

Jani,

I have a drilling that has been rebarreled for 25-35 cal. The markings on the barrel are 6.3X52R.

Sliver,

what make is your drilling? What was the previous caliber before rebarreling? These markings are in the new barrel or in the previous one? Regards.

EJSXS

It's a Fukert that had a 9.2X72 initially and then sleeved to this 6.3X52R.
Cartridges of the World mention that 25-35 Win and the 6.5X52R share same external dimensions. They also mention that they have been loaded to aprox same velocity/energy on both sides of the Atlantic.
My gun is proofed for a 8 gm bullet.

Sliver,

Congrats, enjoy your Fukert drilling. What will be your intended quarry for the new calibre?

Deer, even elk, maybe bear.
