G'Day Fella's,

Thanks for sharing Daryl.

I read about this new cartridge, else where.
As always, us powder burners, find a place and use for these new cartridges.

Not sure how correct Ripp's prediction will be, as popular cartridge's, that has been around for almost 100 years, don't disapear without a fight ..........

D'oh!

Well, I believe most realize this is more marketing and, as Ron S. states, there isn't much difference between the rounds he featured except for bragging rights as to whether you have the newest cartridge.

Seeing the 7x57 existed well before, did we even need a .270 Win? !

---

Most certainly we did. Sales figures and longevity show that. The 270 is closer to a true 7mm than any of the current bullets labeled as 7mm.

Hello,

The 7x57 in a Standard 30-06 lenght action, plus their original C.I.P. chamber design, with 20 mm distance from the chamber mouth to the rifling start. So, it can be loaded, at least, at the same cartridge OAL than the .270 Win and 30-06. This is what I use in mine, made in a 1935 Mauser-Werke action and a S.J.G. new military barrel made for the Chilean Mausers. A kind of a 7mm Creedmoor...The base of a Nosler Partition 175 grs at the shoulder-neck case line.
Loaded that way, the REAL diference with the 7x64 (I had one for 6 years) also in a standard 30-06 action lenght at similar presures and 60 cm barrel, is no more than 50 to 75 f/s with 160 to 175 grs bullets.
Long live to the 7mm Mauser!!!

Hello Rule303,

I didn´t touch my rifle´s chamber! The normal European 7mm Mauser chamber has this dimentions.

The C.I.P. chamber standard for the 7x57 is:

https://bobp.cip-bobp.org/uploads/tdcc/tab-i/tabical-en-page33.pdf

By the way, I do the same thing with my 9,3x62. Because the magazine lenght of my BRNO ZKK is almost 89 mm and because the veeery long Commencement of the rifling in the standard 9,3x62 (28 mm...!!), the cartridges can be loaded much longer than the factory ones without any trouble. And feeds very fine! This increases the volumen of the case notably. And permits the use of many of the bullets loaded with the base at the shoulder-neck junction.

The C.I.P. chamber for the 9,3x62 is:

https://bobp.cip-bobp.org/uploads/tdcc/tab-i/tabical-en-page69.pdf

Sorry for the deviation of the original post theme about the new 6,8 mm cartridge. Anyway, I thought that data are somewhat related.

Best!

Hi PatagonHunter,

Thank you and the following posts answers questions I had. The European manufactures must go for long throats and that makes sense as they often loaded long heavy for calibre rounds. I can comfortably drive a 140 grain .270 bullet at 3200fps in my Steyr. That is up there with the 270 Weatherby. I run it at 3100fps as a very slightly more accurate. As you may have gathered I like throats long enough so I can use the full magazine length.

We are now back on track talking 6.8mm rounds
