The 9.3x62 and 30-06 share the same case so the wildcat you are asking about is pretty close to the 8mm-06 which has been around for years.

From which basis case has the 8 x 65 Skip been derived ?

I believe you will find difference in case capacity between the 8mmx06 and your 8mmx62 to be very small.

The fact cases for the 9.3x62 can be formed from the 30-06 and the 30-06 can be formed from the 9.3x62 should be proof enough that they do in fact share the same case. Keep in mind the 0.003" difference in base and rim diameter is about the thickness of a piece of printer paper.

Look, you're wrong and proven wrong. Just admit it .
As to dimensional specs and tolerances, one "can" also form 7,7x58 Arisaka from .30-06 bras. It even works in a number of cases (pun intended). It is still not recommended. Same here. I certainly do not want an undersized case bottom in a full-power 9,3 x 62 load.

Can you tell me where it is published that this practice is "not recommended"?

Yes. You are welcome.

a) Read the CIP data.

b) Exempli gratia RWS-DNAG handbook, 8th ed., page 350 (in translation: "One shall only use original cases, because the 9,3 in wider in P-1 cross section than e.g. 7x64 or .30-06.")

c)Much louder and RRRRINGINGGGGG in your ears : Vihtavuori Reloading Manual 3rd ed., page 246, last sentence expressis verbis.

Case settled ?

Yes, 9.3x62 cases are regularly made from '06 cases. I would think the 9.3x62 case was originally based on an altered '06 case and was an endeaver to give the German colonists in africa a suitable all-around medium cartridge for all game encountered.

a) It is true that they do state it.

b) It is also true that it is not recommendable and advised against, by those who know better (for two independent reasons, both having been brought to your consideration).

c) It is foremost true that a lot of crap is found in books, and that knowledge is required to separate the chaff from the wheat. We call this process "learning", and learning something new inadventantly is indeed one of the risks of this board. I feel this very risk has hit you; but hey, that's a Good Thing (tm) .

PS Because Mauserkid is looking for an 8mm that: uses the most out of the Mauser magazine as well
I think he should take a look at the 8x68s. What do you think?

Sounds like alottafun, Dan . But isn't it much of work to lathe turn the case bottom, as to dispense with the silly belt ?

I can understand the idea. At first, one would be tempted to assume that it was just one more project "let's make a worse 8 mm", but at a closer look, there is more to it, as I have to admit.

1. It serves to gain more case capacity while retaining an easy-handling overall length, suitable for a standard M 98 action. However - the disadvantage follows on the spot - the bolt face must be opened up. The 8x59 RB Breda uses a standard size case head.

2. One needs no 8x64 factory brass (cheap from Sellier & Bellot, but not *very* cheap), but can use commonly found cases. In the past, that was one very frequent concern and motive for necking up and down existing rounds. In return, you get the extra work of necking up or down.

3. Some people just think they need a belt to underline their gracefully protuding belly . Same goes for cartridges...

4. And lastly, you have a conversation piece .

Mejores saludos,
Carcano
