Was first case Wilhelm Brenneke designed on 64 , then necked down to 7mm

There is a 8x65RS and R also for break actions and such .

Yes, I'm trying to work out if there's any advantage in the 8x64 over my 8-06 Imp. or do I use the 9.3x64 case and neck it down....

I just found an identical thread by Sestoppelman...

If you use the 9,3x64 case and neck down you get 8mm Màzon , a Spanish wildcat .

Not to derail the thread …

Beautiful gun! I remember that one actually, thanks for posting it. If you ever get tired of it..

The 8x64 would be your most simplistic option if you are wanting to convert an existing rifle, otherwise you are looking at magazine and stock work for the larger cartridges with their larger case heads. I think it would be a great choice personally.

My mate has a 8x64 and 9.3x64 in zastava i think. He uses the Tugs . Id say performance is as better than the 220gr woodleigh out of my 3006 but not much difference in killing power.

The 9.3x64 though is on a different level.

Here is CIP’s cartridge dimensions for both the 8X64s and the 9.3X64. I also added SAAMI’s for the 30-06. These should help you figure things out.

8x68S in a std action would be a squeeze. I have a Brno 602 square bridge in 8x68S the oal would require serious modifications in a standard 98

I’ve attached an article by Jack Lott on William Brenneke. It’s fascinating reading if you’ve interested.

Most of the originals were built on standard actions, though you are right, it’s quite the squeeze.

8x68S has OAL of 3.425" while 404 Jeffery is 5.35" long. 404 fits into a standard 98 Mauser after opening the bolt face, changing the extractor claw, moving the loading ramp forward, widening and lengthening the bottom metal, and of course modifying feeding rails. No need to move the ejector or carve away locking ring (e.g. fitting 375 or 416 Rigby in standard 98 action). I guess it depends on what one defines as "significant". As I understand it, bolt face on 8x68S would not require opening, the extractor would also be unchanged, and I doubt the loading ramp would need to be moved much if at all. Would not need to touch locking ring or ejector. Some modification would obviously be needed to bottom metal to handle the wider shoulder. Not a big deal.
Edit: Probably little if no modification needed for bottom metal. The 8x68S has a narrower shoulder than 30-06 which is easily fitted into standard 98 Mauser. The 30-06 has a slightly shorter OAL, just 0.08". And 8mm Mauser is slightly shorter than 30-06: 3.228" vs 3.34" 30-06 vs 3.425" OAL for 8x68S. I would not hesitate to build one of these on a standard 98 Mauser. It would be a fun project for a beginner. The cartridge does have a rebated rim but so slight that I suspect little probability of encountering the usual feeding issues.
