9.3x62mm vs. .375 H&H Mag

[metricman]

The 320 gr Woodleigh load at 2465 fps gets 4316 ft-lbs at the muzzle.

Also, look for the late author John Barsness’ books about him hand loading his CZ550 and hunting Africa with it.

Quite eye opening stuff!

as far as i am aware, john barsness is not late

That post actually made me look that up too. Nothing on my end

 

[hawkeyesatx]

were those loads pressure tested or predicted?

metricman

Tested, and found by piezo to be 60k psi.

9.3 does NOT make the minimum 5,300 joules (3909 ft-lbs) for buffalo and tuskless in Zim, falls short by almost 700 ft-lbs. I'd also submit that if one is going to an Elephant hunt the firearm effectiveness and quality is not something one should skimp on. Maybe scratch for 11 years instead of 10 and get an effective gun. Remember trophy fees are paid the moment one wounds an animal whether it is recovered or not.

Beg to differ.

9.3x62mm 286AF 2480fps 24"Bbl. (Handload = 2480) (66.0 gr. Ramshot Big Game)

Range - Velocity - Energy
. . 0 . . . . . 2480 . . . 3906.0

As mentioned in an earlier post, the authorities, if inclined to enforce the rule, are not going to chrono your handloads. They will go by factory loading which fall short of the limit.

That being said I doubt the issue will come up.

I was able to make a trip to Africa in 2012 where I used my .35 Whelen on 4 of the 8 animals I took. The PH I was with toted a Husqvarna 9.3x62. We compared the merits of the 2 cartridges and at the time a .35 made more sense for me due to the availability of bullets. The 9.3 seems to have taken off a bit since then and sometimes I think about grabbing one.

A few years before that I was able to talk to Chub Eastman, who wrote for some magazines on hunting cartridges. When my .35 Whelen came up, he immediately asked if I’d ever thought about the 9.3x62. At the time I had never heard of it but he had apparently seen how capable it was over in Africa.

I have all the guns I’ll ever need but you guys keep talking about the 9.3 and I may dip into my daughters inheritance!!!

Only reason I can come up with is a Zimbabwean example. 9,3 x 62 is simply not legal for elephant, hippo and buffalo. It doesn't quite make the energy requirement (3909 ft lbs) So with a little increase of velocity, it becomes legal. I don't think any current factory ammo will do it but I believe handloading can achieve sufficient velocity. This is no comment on the efficacy of the 9,3, it has proved sufficient for many elephant.

Please could you sight your source. Don Heath worked for National Parks in Research/Ecology Dept. He may have advised the lawmakers and campaigned for the 9,3 to be recognized but he definitely did not re-write the game laws. I know he was a great supporter of the 9,3 and many hunters have used it in Zimbabwe but it is illegal even if capable.

The following is copied from National Parks Regulations Statutory Instrument 362 of 1990. I have added the brackets for clarification.

Any person who hunts any animal specified in Part A (Elephant,Buffalo and Hippo)
of the Third Schedule shall use a weapon having a rifled barrel
and propelling a projectile of not less than nine comma two
millimetres in diameter with not less than five comma three
kilojoules of energy at the muzzle. ( 0.362 " and 3982 ft/lbs)

I like Craig Boddington but everyone gets it wrong sometimes !

Nhoro, you seem to be right, however nobody cares whether legal or not legal. Three years ago I hunted buffalo in Zim, using my 9.3x74R, this May I gonna hunt in Zimbabwe again. Both very well known outfitters said "You are very welcome using your 9.3x74R.

with due respect to Doktari, that's not how terminal ballistics work.

an 1800 lb cape buffalo has about 45000 times more mass than a 286 gr bullet; and more than 31000 times the mass of a 400 grain bullet.

In thinking about this, something tickled my brain from an Anatomy and Physiology class when I was in college.

The heart runs on electricity. The start of every heartbeat is an electrical impulse from a spot on the top of the heart called the sino-atrial node. If the SA node is destroyed, heart stops beating immediately. Heavy bleeding not even required. If heart stops beating, it doesn't really matter how much O2 is in the blood, because it isn't getting pumped along. Gas exchange (O2 for CO2) occurs in capillaries, and if the blood isn't moving, no more gas is going to get exchanged.

My suspicion about bang-flops on heart shots is the hunter got lucky and hit the SA node. On a human heart, the SA node is about 10-30mm long and 5-7 mm wide, probably much bigger on a cape buffalo, but still not likely measured in anything bigger than a couple centimeters, I expect.

 

[sgt_zim]

The more I think about it, there are 2 other spots on the heart that would likely produce instant death if destroyed by a bullet, all to do with the circuitry and distribution of electricity across the heart. They're both just as small as the SA node, so there's no real way to aim for it. Just gotta get lucky.

I would like to see more factory support for both the 9.3x62 and the 35 whelen however the long range and tactical type is what is influencing the major rifle manufacturers these days it seems with their new models and available chamberings and factory loaded ammo. 35 whelen, 9.3x62, and the 375hh are all great cartridges. If given more support or at least equal to what the 375 already receives I bet we would see significantly more users in the field with them.

 

[Rocco490]

Who currently offers a 9.3x62 chambered rifle in factory configuration that you all would recommend? I wish Winchester did in the Model 70 but wont hold my breath waiting for that to happen.....

 

[John Wasmuth]

These days it’s easier to just rebarrel a 98 Mauser than it is to find 9.3x62 factory rifles anywhere.

Sauer has their 100 series rifles chambered in 9.3x62!
CZ has their 550 in 9.3x62.
There are a few others as well.
One can have a 9.3x62 if they have a shot out .30-06, and have it rechambered and rebored.

I would say any standard 30/06 based caliber Model 70 could easily be re-barreled to 9.3x62.

 

[reineke]

I can only repeat-just take the 9,3x64 and forget about the 9,3x62 or its equivalent the 9,3x74 R
