T S T V Mauser?

[Patrick Chadwick]

8.15x46R The correct (CIP) designation is 8.15x46R (Nominal) bullet diameter 8.15 mm (Nominal) case length 46 mm R = Rand (German for rimmed) But the following designations have been used in the past 8.15x46.5 R Jagdgewehr Normal 8.15 Frohn 8.15x46 R Frohn 8.15 Harstang 8.15x46 R Normal it's all the same!

That should read (Nominal) BORE = 8.15 mm
NOT BULLET

However, these size designations are always a bit odd. If you really want to know what the actual groove diameter is, I suggest you slug it.

All the reloading info I can find here points to 0.321" lead bullets (grease-groove or copper-plated) as the right kind of projectile. So 32-40 bullets will be fine.

But NOT hard-jacketed bullets - they are too hard to deform enough to fill the grooves - the 8,15x46R was concieved at the end of the black-powder era, and the groove depth is a hefty 8 thou, if the CIP data is to be believed. Another reason to slug the bore and measure what it actually is!

Do you think this rifle would be suitable for insertion into Robert Balls book when the 5th edition comes out( I Hope a 5th) as it has a very interesting history from 1933-1945, is a variant of the Mauser and not something many know about?

Unfortunately, I do not think so. It is not a Mauser made for the military, but is really a civilian version. Hence the non-military chambering in the definitely target-shooter chambering of 8.15x46R. It is a bit of a "fringe" application. I think the man to ask is Jon Speed, who has probably done more work than any other on non-military "Mauserology". If anywhere, it would belong in his book on Sporting, Target and Training Rifles - maybe it is already, I do not have this book, it is VERY expensive over here.

The Speed book is apparently only about small-bore rifles, so that's not quite the right spot.

But the Wehrmannsgewehr is covered in the book by Ludwig Olson: "Mauser Bolt Rifles", which has a complete overview of Mausers of all shapes and sizes. I recommend that you get the Olson book!

Oddly, again, CotW specifies that the nominal bore was 0.316" and not the usual 0.318, 0.321", or 0.323" bores found on 8mm or 32 cal rifles. ???

Could you do a bore measurement for us, DaveN?
