I just read about the 9.3 X 62. It appears to be essentially a .375-06. Ballistics I saw was awesome...within 50 FPS of the venerable .375 H&H.

Is that confirmable?

Also, has anyone tested a .375 built on a .358 Norma Mag case (or a .338 Win Mag case)?

I posted a similar question within a month or so. I've been doing quite a bit of searching for data and info on the 375 Hawk, which is basically a 375-06 AI. As to approaching the 375, probably, but it depends on how it's loaded(the H+H). The Hawk figures are quoting 2550 fps with 270's. Good enough for me. One fellow that posts here, has used the Hawk extensively. He's pretty pleased.

I've been shooting a 375 Whelen (375/06) for over ten years. I've never fired a jacketed bullet thru this rifle in all the time I've had it, since I had it made as a cast bullet gun to begin with. I use full charge 35 Whelen loads as my loading guide with equal bullet weights.
I don't own a chronigraph so I can't give you any velocities, but I can say that this one powerful cartridge. I have bullet molds that range in weight from 250 to 300 grains and all are accurate and powerful. I used babbit metal cast bullet, quinched at casting, weighing 235 grains, to punch thru a 1/4 inch cold rolled steel plate at 100 yards. I had no idea that this was possible, I had guessed I'd put a good sized dent in the plate but not punch thru.

.375-358 Norma = 375 Chetfield-Taylor.
Folks apparently are able to handload = to H&H handloads (as opposed to factory loads), which is pretty impressive.

Ijust had made this summer a 375-338 WinMag, aka 375 Taylor. Only had time to work up one load, just to get it rippin' for hunting season. Should do better than this with a little tinkering.....
270 grain Hornady, 72 grains of 4064, 2740 fps. This load shoots fairly good groups, not too much recoil, and is packing around 4500 foot pounds of energy at the muzzle. I am really liking it so far, and once I play a little more at the bench I should find a load that really shines.

Vapogog:

The 375 Hawk is a great cartridge as is the 9.3x62. You will notice the 375 Hawk is the 9.3 case necked up. It has a shorter neck than the 375 Whelen and is wider at the shoulder.

It is a lot of fun to shoot and takes only 59 grains of powder to push a 250 grain bullet to 2700 fps. Similar to a 338 win mag.

I've never recovered a bullet so I'm not to worried about penatration at this point. I'm looking into 270 grain Northforks as well.

Build it, they will come!

200 feet a second, same as in town!!!


seriously.. in a hypo situation, these are guestimates

a x308 based round gives X (call it 2300) velocity
a x06 based round would give about x+200, call it 2500
and
a short mag based round (x338 or x458) would give another 200, so 2700.

just a rule of thumb for guessing

I have a 375 Taylor built on a Mauser with a take off ruger #1 375 barrel.Makes for a great bush gun, will be taking it to moose camp Wed. loaded with 300gr. partitions @ 2500fs.Mark

There's a 9.3X62, and a 9.3X64. I think the 9.3X64 is the one that is about equivalent to the .375 H&H, and that the 9.3X62 fires a 286-grain bullet at around 2300 FPS, whereas the .375 H&H can break over 2600 with a 300 grain bullet. The Hornady "Heavy Magnum" 300 grain .375 H&H is rated at 2700, the same as the .375 Weatherby. I am not sure if it really gives that much velocity, as I have never chronographed the .375 H&H "heavy magnum" loads.
