I've been looking for information on these calibers as well as looking for rifles that chamber them, does anyone know what the 9.3x62 compares to? and I'm also curious if a K98 or M48 can be converted to it. There's a CZ550 chambered in 9.3x62 but I can't find anything chambered in 9.3x64 Brenneke. I've read it compares to the .375 H&H. Thanks ahead of time for any info.

Here's some info on both:

9.3x62 Mauser:

250grn SP 63grns IMR4350 2606fps 3754ft/lbs

The .375H&H falls in between these 2 calibers.

Energy wise, the 9.3x62 Mauser is similar to the .338-06 Ackley Improved, with the .338-06AI having a very slight edge in velocity/energy (on the average) and a better selection of bullet weights (from 160grn to 300grn).

Off the top of my head, the CZ550 is the only production US available rifle I can think of.

I did a search on gunsamerica.com by typing in "9.3". Most of the rifles I found were 9.3x74, but did find some 9.3x62's. None of the 9.3x64's. All the 9.3x62's I found were 4 digits and up in cost! Found one for $795 on a Husqvarna action (that would be nice) but it was marked as sold.

Didn't find any on gunbroker.com.

The Sauer S202, S90 and S92 rifles are all chambered in 9.3x62.

The Mauser M98 and M03 are both available in 9.3x62.

Looking at the velocity and ft/lbs they look like some serious big game hunting cartridges. I'm going to look into having a 8mm Mauser converted to a 9.3x62, maybe with a heavy sporter barrel.

It sounds like these loads hit harder than the .338LM, perfect for Elk. Probably not as ballistically effecient but they kick some serious booty.

It's my goal to build a Mauser that will drop anything that walks on four feet. As long as I don't have to sporterize it, I like original Mauser configurations.

When I was looking at having a .35 Whelen AI or .338-06AI built, I read a bit on the 2 calibers you're looking at.

The x62 works for any North American game, including the big bears. At one time, it was one of the most widely used, general purpose medium bores in Africa.

The x64 will do anything the .375H&H will do.

A friend of mine uses .35 Whelen, but only on Pennsylvania Deer, I never figured that one out, I told him to use .308 or 30-06 as it's cheaper. Then on wild boar he'll use a 44 magnum carbine, I asked him why he didn't use the .35 on boar and his response was it was too expensive.

I saw Saddams 9.3 breneke in the National Infantry Museum Fort Benning Ga.

it was a double gun made in germany.,

Bet he uses a Remington 7600 in .35 Whelen!

Isn't the 7600 semi auto? I don't believe they can use those, not anymore..

He has the CDL I believe

7600 is a pump action. I didn't know that you could use bolt actions in PA, I though it was strictly levers and pumps. Must have my Yankee states mixed up, y'all look/sound alike to me!

How is the availability of bullets for reloading the 9.3's? That's a .366 caliber ain't it?

There a plenty of .366 cal bullets available. The best weight, 286 grains, is available in solid and soft point for very potent versatility.

A K98, VZ-24, K.Kale Turk, 1903 Turk, Gew98, Argie 1909, and any other standard length Mauser action (commercial FN and Zastava actions aka Charles Daly) are quite suitable to the 9.3x62. They are also suitable to the 9.3x64 Brenneke, but the bolt face must be opened up and feed rails significantly altered. The Turk mausers mentioned are "large ring small shank" actions, and a commercial large ring Mauser barrel will not screw into them. They are perfectly strong enough to handle modern ammunition, but for liability reasons you will probably have to have a gunsmith install the barrel if you choose to use a Turk action. But the good side is you can generally pick up a K.Kale Turk (sometimes called an m38) for really cheap.

The Yugo M24, M24/47, and M48 are "intermediate" length mauser actions and while they can be opened up to accomidate a 30-06 length cartrige, I don't recommend it as safe. If you want a safari caliber out of an intermediate length mauser, the 376 Steyr is the way to go, in metric terms the Steyr is 9.5x60, but the bolt must be opened up. The parent cartrige to the 376 Steyr is the 9.3x64 Brenneke.

The 9.3x62 is an excellent choice for the "one rifle hunter" since it developes such wonderful energy levels with much less pressure than modern cartriges. Husqvarna even chambered m96 mausers in 9.3x62 and I've never heard anyone complain, or any stories of exploding rifles. The m96 is almost the m98 action, minus the third safety lug, the lip on the bolt sleeve for gas handling, and the enlarged gas ports in the bolt.

If you want to rebarrel a bent bolt k98 into 9.3x62 then I recommend that you contact Lothar Walter about a custom barrel. However, I think that if you are going to make a classic hunting Mauser, that you might consider a nice wooden stock with schnabel forend or clean classic lines found on "grade b" mausers of the early 1900's.

Anyways, I hope this helps.

Bolt actions are the most widely used that I've seen, and some lever guns.

Barnes Bullets just announced 2 new Triple-Shock X-bullets in 9.3mm; a 250 and a 286grn.

These are the Barnes solid copper expanding hollowpoints. I've read that they are very accurate and offer excellent terminal ballistics.

That's cool, a regular supplier of brass would be nice too!

I guess brass would probably come from RWS, A-Square or Norma.

You can resize 30-06 based brass to 9.3x62.

9.3X62 is the third most common Elk cartridge in Finland. The others are .308 (a bit light for elk but works) and 30-06 (a bit better). Nowdays every second Elk rifle sold is in 9.3X62 but there are so many 308s and 30-906 that it will not become the "king" anytime soon.

Sako 75 and Tikka T3 are manufactured in 9.3X62 but might not be imported to the USA as a regular item. I do not know whether this is so. Here they are sold every day.

Lapua (and Norma) makes brass for 9.3X62 so you can buy match grade quality brass for it.

9.3X64 is common in Germany and not much elsewhere.

Sako offers also 9.3X66 Sako that is even heavier hitting than 9.3X64 but it is not sold in the USA´.

My sggestion is to choose 9.3X62 because of ammo supply which is the easiest of these three. If one needs .375 H&H power I suggest the buyer to buy one in .375 H&H.

In Africa ammo for .375 H&H and 9.3X62 is easy to get. For 9.3X64 not so.

Thanks for the info!
