Difference between 375 H&H and 9.3x74R
      #151214 - 20/01/10 12:58 PM

In looking into the 9.3x74R, I noticed most say it's pretty close to the 375H&H. So is there any practical differences or advantages of one over the other? Just one of those "Inquiring minds want to know..." questions!

Is there a big difference in typical weight of guns and felt recoil?

A small difference in velocity and a .375 is the legal minimum for DG in some countries.

Remember the .375 is already considered acceptable but marginal by many, so going lower is more marginal. However the 9.3x74R will still kill everything with the proper bullets and shot placement.

The 9.3 can be purchased in lower priced DRs however, as it is often available in medium calibre models while the .375 is usually in the big bore models.

A great driven game and brush calibre which is capable of taking DG as well.

So when you say .375 is usually in big bore models, do you mean larger framed and heavier?

I know felt recoil is subjective, but are they also similar in that regard?

The .375 H&H Belted Rimless can achieve at least 200fps more than the 9.3x74 with similar bullet weights and barrel lengths.
The 375 has far greater case capacity, and it also runs at much higher pressure.
In similar weight rifles, the recoil of the .375 will be more by a noticable amount.

I see the 9.3x74 factory ammo as running 2,300+ change with a 286gr. bullet, while the .375H&H runs 2,500fps and change with a 300gr. Loaded with the same weight as the 9.3, ie: 285gr. bullets, the .375 will usually run well over 2,600fps quite easily, maybe more, afterall, my 9.3x62 does 2,519fps with a 286gr. Norma.

Minimum Legal caliber! Remember this if you plan on taking yourself and gun to Africa. Believe me if you go to Africa you will want to take your double. You might get to use a 9.3 on dangerous game but if thats all you have and you are hunting the big 5 some eyebrows may be raised when filing out permits.

Daryl notes the fatory specs, but we need here a discussion of the actual performance of factory loads in both;

Seems .375 loads generally meet or at least get very close to factory spec. But 9,3x74R? Have heard reported that some 9,3x74R factory loads fall very short of the standard velocity spec and more approach performance of the 9,3x57 {286 @ 2150 fps +-}.

Hopefully some comment here by those who have chrono'd a multitude??

Also, a 200 fps velocity spread between the two might not show in many cases on game at 50 yards, but does represent about +- 100 yard difference in useful field trajectory.

This discussion is a little like the enjoyable .300 Savage or .308 Win vs. .30-06 discussion that never ends, which is to say that the '06 will ALWAYS beat the smaller-bottled rounds for all-round field use just plain due to the amount of velocity it can generate and the flatness of trajectory thereby created.

Of course if deer at 100 yards is on your plate the diference between 9,3x74R and .375 H&H is non-existent. The critter will never know what sent him to the deepfreeze. Hitting at longer range, especially unknown ranges in the wind might very well be noticeable.

IF, did I say that...yes, IF a guy can shoot well enough at the farther ranges to realize the difference.

Factory loads chrono'd from Merkel 140 23.6" barrel:

286gr CDP (Blaser): 2257 fps - factory stated 2295 fps
286gr Oryx (Norma): 2319 fps - factory stated 2362 fps
293gr TUG (RWS): 2288 fps - factory stated 2278 fps

P.S. Factory stated V0 for TUG 293 in 9.3x74R is 2278fps and for 300gr TUG in .375 H&H is 2590fps - therefore difference of 312 fps. However on 300m 9.3 TUG is suppose to do 1740 fps while .375 TUG is suppose to do 1800 - only 60fps difference remains.

Thanks 93.

Your last comment is interesting, since I assume {???} both the 9,3 and.375 TUG's have similar form {ballistic coefficient} and of course similar but not the same sectional density. Strange the nearly identical speed at 300.

Do you have drop tables for the two?

I guess it depends on what you want to shoot/hunt with it.

I have no experience in Africa with them but an old friend of mine who lived and hunted in Africa for many years had. He once told me (I think it was him) "the only difference on game between the 375 and the 9.3, is that at 20 yards and with a good solid, the 375 exits the other side of an elephants head about 150 fps faster than the 9.3"

Both are magnificent cartridges and, with the right bullet and proper shot placement, either will kill anything you are likely to point it at. But take note of what srose said too,

Do check the minimum caliber requirements of the country, should you ever decide to take the 9.3 to Africa on big game. For some things, bigger is definately better.

Both are excellent shells though, I own and use rifles in both calibres. Great sambar and pig calibres, my double 9.3x74 is great to chase fallow deer with, very emphatic killer there with little meat damage, and either cartridge will do the job on our buffalo here too.

You will have little if no problems with a 9.3x62, x64 or 74R in Countries that stipulate 375 minimum.
The authority's have no clue and the majority of PHs accept and admire the 9.3s ability to kill any game.

The difference between the .375H&H and 9.3x74R is analogous with the difference between the .270 and the .280. To some people the difference is significant, to others it is not. I prefer the .375 but I have both. Both are great all-around cartridges.

Two years ago a buddy and I were dropped off in the wilderness of Alaska for a week of Caribou hunting. He took a .300WinMag and I took a .375H&H. Every time we got into a place where there was potential to be ambushed by a bear, my friend wanted me to go first. In such an environment I would regularly choose the .375H&H over the 9.3x74R but I still wouldn't have felt under gunned if I had taken a 9.3x74R instead.

NitroX makes a good point about the guns. If you want a lighter double then I don't think the .375H&H is going to be a choice unless you go with the flanged version. On paper, the 375 flanged loads are closer to 9.3x74R loads. But you will find many more double rifles to choose from in 9.3x74R than in 375H&H. Consider that the makers offering 375 doubles will build you a 9.3 but some makers of 9.3 doubles won't build a 375.

Some one wrote that the 375HH have a tendancy to break up the bullets a bit easyer then a 9.3mm, but with modern premium i doubt that would be a problem. But the old germans in africa swore by there 9,3mm, it killed much better then the 375.

9.3 drop at 300m is 22"
.375 drop at 300m is 17"

No doubt .375 is balistically superior - that 300fps difference is there - and those do drop less, make bigger wound chanell and penetrate deeper as long as bullet is up to its job - speed difference and atributes described come at price - recoil or weight and price of a rifle.

.375 has a jump start of app. 100yds - 9.3 does at point blank what .375 is doing at 100yds. Is there a difference? Sure is. Do you need it? Your call (I don't). At what cost? - Bigger recoil or heavier rifle that costs twice as much...
