Pre-64 Winchester M70 - 9.3x64?

[sambarhunter]

my `64 has a 26" barrel as it should have.

Hello HWL,

Yes. I am talking about that. The velocity differences for this 4 cartridges, 7x57 vs 7x64 and 9,3x62 vs 9,3x64, in factory loads are clear, by a good margin, around 200 f/s for the common bullet weights. In hand loads with similar pressures and barrel lengths, the differences are notably smaller, also by a good margin, 100 f/s or less!
This is not theory but reality. Anticipated by theory, by the way!
Best!

I am guilty of the deviation of this thread original theme, fascinating one about the extremely rare, unknown until now, original Winchester 70 pre-64 9,3x64 Brenneke!
Would be very interesting to know more about this, and others, non-standard cartridges Win 70 pre-64 factory offerings!

Breath some life into this old thread with something interesting I found on Pre64.com.

Funny it doesn’t mention which 9M/M?

I always thought it was the 9x57 that was referred to concerning the pre 64

Edit: I realized where I read it at

9x57 is correct.

 

[deewayne2003]

9x57 is correct.

Agreed!…. However, notice the article mentions .300win as a catalogue caliber but not .300H&H?

.300win didn’t come out until 1963; I personally used to own a .300H&H Supergrade and the barrel stamping was “.300 Magnum”

The next time I’m in San Antonio; we are going to take the stock off the 9.3x64 rifle and see what the factory bore diameter stamping is on the barrel.

My 300 H&H is also marked 300 Magnum.

My 300 H&H is also marked 300 Magnum.

My 1948 Super Grade is marked 300 Magnum as well. The gun store it was at had it marked 300 Win Mag. That's why I got such a good deal. They thought it was a rebarrel. lol

Fantastic rifle and cartridge. I am caretaking one built on a Lefty Ruger M77.
