At the start of the 20th century the famous German gun and ammunition designer Wilhelm Brenneke (1865–1951) was experimenting with the engineering concept of lengthening and other dimensional changes regarding standard cartridge cases like the M/88 cartridge case, then used by the German military in their Mauser Gewehr 98 rifles, to obtain ...
The twist rate for the 7x64 is 1 in 8.66 inch against 1 in 10 inch for the 280 Remington. Nearly every European rifle producer offers the 7x64 as a standard caliber. The .280 Remington does, however, have a larger than expected number of European users in imported self-loading rifles such as those by Remington.

The general penalties for using bigger, more powerful rifle ammunition compared to smaller cartridges are increases in recoil, jump, flash, and barrel wear. If you want to use very long for the bullet diameter bullets the relatively fast standard twist of the 7x64mm can be a bonus compared to the slower standard twist of the 7mm-08 Remington.
In many instances, the ammunition was packaged in boxes that read "For Borchardt and Mauser Automatic Pistols". The Borchardt case was also the basis for the 1896/1903 Mannlicher 7.65×25mm self-loading pistol round and the 1902 self-loading carbine models which used a lighter charge.
