9.3x62 with 325 Oryx or 320 Woodleigh PP

[sgt_zim]

I'm gonna try 250 grains ttsx in my 9,3x62 for flatter tradjectory on moose and wild bore.

You might also take a look at Nosler AB 250s. Slightly higher BC than Barnes, and at MV of 2500-2600, it's a duplicate of 338 WM in the same weight bullet. I'm working up loads for NAB right now, actually, going to go put them down range this weekend.

The 320gr Woodleigh was designed for use in the much larger cased 360 no2 round. Not sure what the idea is behind the Oryx.

As with all calibre/ bullet combinations there is a happy medium between weight and velocity. Out of the 62mm case the calibre reaches its maximum potential with a 286gr bullet at 2300fps, give and take some, ie 250-300gr at 2500-2200 fps. Trying to push a 325/320gr premium bullet at enough of a velocity to open reliably from the 9,3x63 is a bit of a tall order.

Rats. Also meant to ask...

Velocity for 416 Ruger and 404J are around the same as velocity for the two heavy 9.3 bullets. I wonder why 2200-2250 is considered a problem for a 9.3 and not for 416R or 404J, especially given the 9.3's higher sectional density. I would think the higher SD would force the 9.3 bullets to open even better than the 40 cal heavies.

I'm not trying to start anything or be snarky, I'm genuinely curious. Thoughts?

Not at all Snarky Sgt Zim. Of course it could work. I guess its sort of the same as the 350 or 380gr .375 bullets. It just takes away some versatility of the calibre.

We regard the .400 calibre cartridges as short range DG cartridges so velocity is not of that much concern. As long as the very heavy for calibre 9,3s are stabelizing in the rifle, not tumbling on impact and one doesn’t chase velocity pushing up pressure dangerously they’ll be good to go.

I’ve just invested in a 9.3 and, buffalo aside, I feel the extra velocity and bc of the 250grain really adds to the versatility of the cartridge. The problem here is SA is that the Accubonds are hard to find and very pricey...

 

[sgt_zim]

They're not inexpensive here - midway usually sells them for about 46 USD per box. I bought the 2 boxes I have on clearance for 26 USD each. And they're on clearance again for 28.60 right now. I may buy a couple more boxes today. That's cheap enough I don't mind shooting them as practice rounds.

Thank you

the woodleigh manual shows several loads around 2200fps for the 320 gr bullet in the 9.3x62 - same velocity, as far as i can determine, as the 360 no.2 .
so, i would think it ought to work similarly

Using the Miller Twist Rule, SG for the Woodleigh 320 PP is 1.89 in a 1:14. Anything above 1.5 in Miller-world is considered stable.

I can't find a published length on the Oryx 325 anywhere (not listed in my Norma book, either). It should stabilize in a 1:14 as well as the Woodleigh.

Just rustled up some 320 grain Weldcore's to go along with the stash of 325 grain Oryx's.
Going to use BigGame to work up to 5.3 kj ME and 1 MoB (minute of buffalo).

Got my winter planned out... should be fun.

Hi,

I am using the 9,3x62 since 2018 as my main big game rifle. The biggest "game" I shot with it is a wild cattle, big bull.
After trying some normal cup and core 285 grs bullets, I think the monometalics 250 grs work the same or much better! I have Hornady GMX, Barnes TSX and my favorite, the TTSX 250 grs. Also I have some boxes of 250 grs Accubonds and around 150 pieces of H-Mantel 258 grs. I am covered for my uses!
I have two and a half factory RWS 293 TUG, 50 rounds I have to try yet...
If I would need more weight, perhaps I would get some 285 grs Nosler Partition, 285 Norma Oryx, 285 Swift A-Frames and 285 grs Barnes TSX.
Anyway, I would like to try heavier ones like 300 grs A-Frames or the heavier 325 grs Norma Oryx, but feel I am done with any tough 285 grs ones.

The 325Gr Norma Oryx is excellent lion medicine out of a 9.3x62mm Mauser.

Hi H-H,

I have not hunted for african lion, and I almost sure will never do!
But from friend´s reports that did it, general african reports and talking with some Namibia PHs that works with clients from here, they said to prefer not to tough bullets that open quickly but penetrates as well. Perhaps something like the Nosler Partition 285 will do. What do you think?
Best Regards

I used a hand loaded 300 grain A-Frame on the last buffalo. It's my current favorite load in the 9.3.

Then again, I use A-Frames on everything....

Anyone ever load these? They sure seem like they'd be good medicine for feral hogs. The published data on them looks an awful lot like published loads for Hornady FTX 325 gr for 45-70, with about another 100-150 fps velocity out of the 9.3x62, and of course way higher SD in the 9.3 bullet.

@sgt_zim
I've been reading the very informative book called the 9.3x62 Mauser journal. Very informative on all things 9.3x62.
Those big big slow bullets sure do a number on big hogs. If hit in the chest it appears the blow big chuncks of internal out the other side of 300# hogs. Usually dead on the spot but if tracking is required it's only a short distance and Stevie Wonder could follow the blood trail.
They say 2,100 to 2,200fps is the best speed for these bullets.

The big heavy bullets in the 9,3x62 are indeed a punch full of power Bob. That book you are reading is the best ever on compiled data on the fantastic 9,3x62.
