Just thought it worth posting that I got an email back from Woody at Lothar-Walther today saying that the 10.75x68 reamer was on their list of "new" reamers and is in-house now He also earlier told me that they can do either of the groove diameters and can also turn Ray's classic H&H barrel profile too. I would think the .423" groove diameter is the proper one for these??? I suppose I need to check Howe's "Modern Gunsmith" Vol-2 again for twist and barrel configuration.

.423 groove diameter is the only diameter for a 10.75 Mauser of whatever millimeter length brass. This is true.

RIP,
Lother-walther has both .418 and .423, as some Europeans request the .418 bore for the 404s, `10.75s and some Arms companies produced 404s in that bore diameter, so I think what he is saying you need to specify when ordering, and I recall someone on the forum got a .418 bore rifle and was haveing all kinds of fun!!

but, of course, you are correct in your post, all 10.75s and 404 should be .423....

I just checked my copy of "The Modern Gunsmith" by James Howe and in his cartridge drawings in Vol-2, he has both the 10.75x68 Mauser and the .404 Rimless Magnum shown with .423 bores. A good reference / sanity check from years ago.

Cogswell and Harrison had .418 bores in .404 Jefferys and so did another company but I can't recall the name..Some of the small shop English firms used .418 barrels I am told, I have only seen one and it was a C&H....

Pfeifer,
Are the Lothar barrels ready to go at this point in time? After a horrendous search I've finally located a reamer in Australia, but the chambered Lothar barrel would be much simpler... except now I need a smith with headspace guages...??
Cheers...

I believe this is what I would infer from Woody Woodall's (works at LW) email as he said that the reamer was "in house". So I belive that they take a .423" groove diam barrel and "long chamber" with the reamer so all your g'smith has to do is set the headspace like you said - with gauges. The part I also like about going with an LW barrel is that it can be had with the very classy vintage H&H barrel profile...know which one I mean? I can post a pict of an orig I keep around.
Hope this helps,
Jeff P

Pfeifer,
Kindly psot a picture of the H&H contour to which you are referring.

Tahnks,

I had a chance to shoot fla3006 10.75.... with a steel buttplate and might have weighed 8.25#...

You're more than welcome Jeff! This is a nice round, lots of power in a relatively small package and as you say low recoil (at least compared to the other stuff being passed around that day!).

Here's a picture of a vintage H&H in ".30 Super Mauser". Also note the cocking piece sight

Ray, Vickers were originally made with the .418 barrel.
