9.3x62mm vs. .375 H&H Mag

[Tam Dl]

Hey guys, please take a moment to contribute to my thread:

.375 H&H Mag Vs 378 Weatherby Magnum.​

 

[hoytcanon]

You’ve lost me. All I did was provide data that the 375 has a small edge ballistically on the 9.3. And then I pointed out that the 9.3 seems to have a fit and functional edge. So there’s probably a trade off to be made one way or the other. There’s no right or wrong answer

In a nutshell... there is no tradeoff to more performance other than recoil, so let's just say that... we don't like recoil.

Or we could say we don't like inefficiency. I couldn't dig up my chart, but it states there, and I have seen it elsewhere, that the recoil of the 9.3 is the same as a 300 win mag, which sounds at least 2 noticeable levels below the 375.

And then there is muzzle blast. Probably could be a slight difference in barrel length, if one is into that.

Heath hunted with the 9.3 as a boy when he went after buffalo, in an area with terrorist activity. Maybe that was something that formed his impression that one should be able to fire, carry, and afford 30 rounds of ammo. I don't fancy having to shoot 30 rounds out of a 375.

It is also pretty easy to set up standard actions for 30-06 category ammo. Easier to fit boxes where those are indicated.

Right or wrong the current prejudice is against belts.

Ammo weight.

In cars and rifles, performance isn't just power, it is also handling.

 

[Rule 303]

Once again you are arguing that the .375 is more powerful. I don’t think anyone disagrees with you.

But they do. Some are saying, in essence, the difference in power is inconsequential. I am saying there is a difference and it is not inconsequential in all cases and some of the points put forward are, I believe, floored. Hence my reference to the 35 Whelen. Nowadays with better powders and, mainly, better bullet design, I believe there is less difference than years ago.

As somebody said it is more about where you place the bullet than the calibre.

If we talk about what is the better cartridge, I would say the one you are most comfortable with and the one you shoot the best.

 

[Tam Dl]

There is a difference in some cases and not in others, I would agree. So if one is after controlled expansion and a big energy dump, then the 375 is going to have an advantage. But if one is shooting solids not so much.

May I interject here, that this thread has never been, or will it ever be that the 9.3x62 is better than the .375 H&H. With the capability of the new powders, and the efficiency of the case, the 9.3x62, can equal the old, 20th century loads of the .375 H&H, if loaded to 64k psi.
Now, to also say, that factory loads seldom reach published velocities. The factory loads on average, run 150-200fps slower than advertised. They usually use 24 to 26 inch tight dimension test barrels that run minimum specs in order to get such claimed performance.
So, if a person were to use a magnum cartridge, the cartridge is also loaded more to potential, and running 62k - 64k psi. If hand loaded, it can improve performance a slight amount, compared to, let’s say, a cartridge that is loaded at 56.5k psi.
As shown, the 9.3x62, usually have a 22 inch barrel. That barrel length is about perfect for powder burn rate and getting optimal velocities.
So, the official statement is, and always has been, that the 9.3x62 hand loader can achieve “EQUAL” velocities of same bullet weights as the old, 20th century, advertised factory velocities, as the .375 H&H.
Not better, or outdoing the .375 H&H!

try getting 2700 fps out of a 9.3x62 with a 270 gr bullet or 2500 fps with a 300 gr bullet. i own and reload for both of them and have shot a buffalo cow with a 9.3x62. there is a reason your need at least a 375 H&H for dangerous game in most countries in africa.

So... the 9.3X62 can potentially be as good as the .375 H&H was pre-WW1. Where have I seen this brilliant marketing before??? Oh, yeah! "BUD LIGHT."

 

[grand veneur]

In Europe we tend to compare the cartridges 9,3x64 Brenneke and 375 H&H Magnum.

The cartridge 9,3x62 is equivalent to the cartridge 9,3x74R and is therefore behind the cartridge 375 H&H Magnum in terms of performance. Cartridges are to be loaded to the maximum allowable pressure and not above, what can be a very uncertain matter. Don't forget that we are talking about hunting in Africa where temperature also plays a role in terms of pressure.The British developed tropical loads for this reason, but sure, they remained on the very safe side with their loads.

 

[John Wasmuth]

One can easily argue that modern powders make the 9,3x62 the equal to the 9,3x64. The problem arises that it is harder to find quality bullets that don’t come apart at the increased velocities.

You really should give it a rest.

That is interesting. Most of my experience is with the Prvi bullets, where my mental process is that even if the bullet breaks up it is like a double tap from most other cartridges. Reasonable thinking on a moose.

For the nasties I have the TSX and those hydro mono solids. What says the consensus on those ones?

Historically Heath/Ganyana, said he had traditionally preferred the 9.3x62 to the 375 because of better bullets for the 9.3. Not sure when that was the case. Funny how things change around.

It’s been my experience that if you drive the PPU 285 faster than 2450 they tend to shed their jackets, they still kill big stuff very dead. Note that I don’t use fail, if an animal dies as the result of getting shot by our cartridge/bullet combo it’s not a failure. Hornady interlock bullets are not much thicker and at 2500 fps and faster they tend to also shed their jackets. They do kill large game well enough. They are fine for most any game we’d be after save DG. The better bullets like A Frames NF, Barnes, tend to hold together a little better in my experience.

Good choices for the nasties.

I've been on forums for a couple decades... only new here, so I know how ignore works... and it works on both sides of the coin... done.

We try to operate with a little more decorum here than what is typical on other forums. It’s a good bunch and we really all try to get along.

I don't really have a problem with him. He is a bit like I can be, very direct, saves on the typing and all fuffle. The longer I am on Forums with Americans and Canadians on them, the more I try to take care not to be so direct and use a bit of cushioning speech. Not knocking the culture as this method is very cultured and polite. Just pointing out there are other method out there and often no offence is meant.
Anyhow that is just me.

I am not, not "getting along." Expressing opinions when opinions are asked for should be expected and anticipated, this is after all an opinion forum, whether based on first hand experience, or as is so often the case on the internet, "armchair experience." Nobody is asking you to agree, feel free to counter anything you disapprove of, as will I, but telling someone to "pipe down" is fighting words where I come from. After 35 years in the career I come from, I don't take kindly to that. I am fine with the ignore function in both directions, if that brings you peace.
