HI
Are these two rounds based on the same basic case??

How does the 9.3x64 compare to the 9.3x62 in performance ??

Can these cartridges be chambered in standard length actions or do they need magnum length ones??

thanks

later

No, they are not based on the same case. The 7mm is based on a .30-06 size/ type case, so is the 9.3x62. the 9.3x64 has a unique case design, slightly thicker from the head, all the way to the shoulders, than the "standard case. expect about 300ft/sec more MV from the x64 case. (also loaded to higher pressures I presume.) I wrote an article on the 9.3x64 a while back, I will try an post it.

Thanks Karl S- that would be great if you could post the article.

The 9.3x64 Brenneke: the head diameter is .495, the base is .507, the shoulder is .474 and the shoulder angle is 17o30', with a neck length of .343.
