The 9.3x62 was designed in 1905, the 30-06 in 1906...

The .30-06 was actually developed in 1901, with some tweaking to the rim and neck in 1903. The final version with a spitzer bullet was officially adopted in 1906.

I'm sure Otto Bock wasn't using the .30-03 as the basis for his 9.3x62. The cartridges are actually quite different in shoulder and neck length, having been developed for particular bullets. I would assume that the .30-06 came about from the 7x57 after the Spanish-American war, and the 9.3x62 was developed from the 8x57I.

The 9.3 x 62 is also of a larger diameter at the rim and web than the 30-06 or the 7 x 57 family of cartridges. It is unique in that regard. It has a measurable advantage in capacity over the 30-06. That's why it is the parent case for the Hawk and Scoville wildcats. The differences are slight enough that 30-06 brass will fireform to 9.3 and headspace.

Thanks for the info on the 9.3 -I just might use it sometime...

i have a husquarna fn 98 that i bought for 200 us, and a a semi inletted stock for 150, and i did the work on it myself , it has a couple of flaws, but i ,ade it after me and my shooting styles, and iam getting a laminated semi-inletted for it aswelll, and the caliber is 8mm mauser. its a great round, and u hope that other 8mm cartridges will make sure taht it has have it`s comeback . When that barrel is worn out, i thought about having tha 404 dakota trimmed down too ca 70mm and get that in the rifle.
