I purchased an old single shot bolt action German stalking rifle. I has markings under the barrel that read 6.2mm and a mfg date that I believe to be July 1910. There is no caliber designation markings. I have ordered some cerrosafe to make a chamber cast in the meantime what are the likely candidates for that era......Thanks.....Hutt

There isn't a big number of 6 mm European hunting cartridges. It could be chambered for the 6 x 58 Mauser or Forster, although the Forster was first listed in 1934 DWM catalogs

You should measure the bore diameter with calipers and we could get alot closer to what you are seeking for an answer.

A 6mm .243 bullet will drop thru to the other end a .257 will not.......still don't know. Tried two lubed chamber casts and non would release. Had to heat back out. Will try wax next

Actually there are a more than a few 6mm calibres for European sporting guns. But you do really need to do a chamber cast to get an accurate identification.

Do that , get the measurements and you will likely get an identification quick-smart like .

NOT an expert on early markings, but is the 6.2 the bore diameter? Could that make it one of the 6.5mm's?

6.2mm = .244"
6.5mm = .256" (actual, VS todays "standard" 6.5 bullet of .264)

The actual 6.5 (.256 ) would be a likely guess

I have a Collath drilling from the late 1920's that is marked on the flats as being a "6x58R". I had this gun slugged and it turned out to have bore of .261 which would correspond to a 6.5x58R Sauer and indeed an empty case drops in snugly. I doubt the gun was rebored so I have to wonder whether it was mismarked or if guns of this caliber were so marked. Going to Germany in two weeks and will pick up some bullets (Degol)in .261....but it is a mystery which I intend to talk about with a friend that works at Frankonia.

Since 1906 the only thing spectacular that has happened was in 1925 when God created the .270 Winchester.

Cal, Love your byline!!!

I would think there is a good chance that the 6,2 proof mark might refer to the 25-35 win.
Both the 25-35 and the 30-30 had a following in pre war Germany. I have seen several drillings chambered for the 30-30 and at least two bbf's chambered for the 25-35.

I did a third cast and the results were measured and compared to the charts in the cartridges of the world...............turns out it is a 6.5X27Rmm
There was a gouge in the chamber keeping the cast from extracting. The bore is fair at best so The rifle at a smith being relined and chambered to 25-20. It is a very close match to the original as far as ballistics are concerned. The rear barrel express sights should be closely regulated to the 25-20. A closer match dimentially to the original chambering was the .256 win magnum.
