Dangerous Game with 9.3x62?

[K95]

There is no replacement for displacement.
The 9.3x62 is 80-95% (depending on the load) of the 375H&H in terms of energy.
But it is not a 375...

Reality - no one will most likely ask as long as it's OK with your PH/outfitter.

Best plan - Step up to a MA bolt head and order a 375H&H barrel along with a 300WM.
Face it, your mate is nearly hooked.
Might as well jump in the deep end at this point.

Yes it only takes a minute without any tools to change the bolt face over. He can then ponder over a 416 or a 458 Lott if he needs the extra punch. I have a 9.3 x 62 barrel rechambered to the 9.3 x64 Breneke which has the same power as the 375

9,3 x 64 is a way more powerful option if you are in love with this diameter. Not sure it fits a standard Mauser action though.

Cartridge OAL: Yes, bolt face, No.

You only have to open the face up slightly and I found all standard rounds like the 270 , 3006 will work fine with it

I own two CZ550 9.3x62 rifles and the idea of rechambering one of them to 9.3x64 never occurred to me until I reread this thread. Can I simply have it reamed to 9.3x64 or does the bolt face also need to be opened up? Either way it should be very simple work for a competent gunsmith.

I already own 7x57 and 7x64 rifles so having a 9.3x62 and 9.3x64 pair is very appealing. The only downside is it would make my 375H&H even more redundant.

I answered my own question with a little bit of research. Yes, the bolt face will need to be opened a little bit.

The 9.3x62mm Mauser is absolutely fine for hunting dangerous game (except for body shots on bull elephant) in the context of a visiting client hunter (where legal, of course). More Cape buffalo have been harvested in Portuguese Mozambique with this caliber than perhaps all other calibers combined (with the .375 Holland & Holland Magnum being a close second).

Just use good bullets like 286Gr Rhino Solid Shanks and 286Gr Rhino flat nosed brass monolithic solids. 286Gr Swift A Frames are excellent, as well.

Hi Bonk
Yes a good gun smith should be able to do it in no time . Just have to screw the barrel out of the action, cut the old chamber out with the 64 reamer on a lath. Open the bolt face up a few thou and re fit the barrel. He may have to do a little work to the magazine follower, then again he may not depending on the action. Well worth doing seeing you already have a 62 . I have a left handed Sako Barvarian with a 20” barrel in 9.3 x62 and a custom left handed 375 Ruger that hasn’t been used since the conversion. Good luck with it and let me know how you go . Btw your not in Aus are you as I have a reamer.

@K95, no, I'm not in Australia but thank you very much for the offer. I really appreciate it. I'll keep you posted. Not only do I have to decide whether I'll do it I have to decide which rifle to use.

Having a custom Mauser in 9.3X 62 and a pre-64 Model 70 Winchester in .375 Holland makes the choices easier. For irritated cats and bear, there is a pre-war Model 71 in 450 Alaskan. Fast cycling and 400 gr FP at 2K p-fps.
Then there are the pre-64s in 338WM,338-06, and 35 Whelen. Being a rifle looney has its advantages...

Hi Bonk,

The main thing about 9,3x62 vs. 9,3x64, as the one between 7x57 vs. 7x64, is:
Will be used factory or handloaded cartridges?
I have had both 7x57 and 7x64. In a Mauser 98 with a standard CIP barrel, and with its magazine lenght, the OAL of the 7x57 can be a lot longer. So, the velocity difference, loading both cartridges at similar pressures, being all other factors the same, is no more than 50-75 f/s.
The CZ, and my BRNO ZKK as well, have a much longer magazine lenght than a std M98, about 88 mm. This, plus the looong standard frebore of all 9,3 European cartridges allows to load the 9,3x62 at 87 mm OAL. Again, the difference is no more than 50-75 f/s vs. 9,3x64. Loading both at similar pressures with same barrel lenght.
Using factory ammo, then, the differences are a lot bigger, of course!

Best regards!

Here is a thought. If you look around, you will see articles saying you can reload 30-06 brass to 9.3x62. But then others say one should not do that because the head of the 30-06/308 family is a few thou smaller than the 9.3x62 standard, which is true. Then someone else mentioned, sure, but have you measured your actual brass, because the stuff he had was the same rim size as the '06. So I whipped out my caliper, measured some Prvi brass, and it was truly the same diameter, so you would not need to change the 308 out to shoot 9.3.

That was as far as I got, however if a reason for owning a 9.3 was to be able to replace ammo in far off places, it doesn't make any sense to handicap your gun so it might not run some ammo made to original specs, that you pick up at the end of the road somewhere...

Apologies if this has already been covered.
