Gentlemen,
Thank you very much for your responses. Is there a preference for any particular bullet weight? I read in my Nosler No.5 manual that the fella reckons it has a range of 180 yards...the trajectory of a 250 sure doesn't look like that.
Any thoughts?

Would anyone have a .338 WM and a 9.3X62? Overlap? I like both,but need room in the safe... I have both. Not sure that I need both, but I seem to find uses for each. My 9.3x62 has a 20 inch barrel while the 338WM has a 24. My 9.3 is also a bit lighter by about 3/4 pound. The 9.3 is built on a Charles Daily CRF action while the 338 is on a 700. Distinctly different guns with similar ballistic capabilities, at least out to 300 yards, after 300 yards the 338 shines.

I also have both a .338 Winchester Magnum and a 9.3x62.
The .338 has a 22" barrel, the 9.3x62 a 23.6". They're both fairly light rifles, the .338 7-3/4 pounds scoped, the 9.3x62 8 pounds. In recent years I've used the .338 mostly with bullets of around 200 grains at 2900-3000 fps, and find that it works great, killing more quickly than with heavier bullets, and recoiling less.
With heavier bullets I tend to use the 9.3x62, since it just about matches the .338's muzzle velocity with 250's (around 2650 fps), with noticeably less recoil. With 286's it's a great killer at the moderate ranges typical of African thornbush or American timber hunting.

Mule Deer - Since this is a 9.3 thread and we are also discussing the 338, I have a question and would value your opinion.
I have an upcoming spring grizz hunt scheduled for mid May. This will be my first large bear hunt, I have taken blackies which of course are not in the same class. The 2 rifles I have in mind are the 338 and 9.3. For the 338 I have 210 and 250 NP slugs, for the 9.3 250 Barnes TSX, 270 Speer hotcor and 286 NP. I would not use the 232 Norma for grizz.
I can shoot both just fine and I suspect ranges should be 200 yards or less on this class game. What is your rec?
Thanks for your input!
Regards
TT

Either round, and any of the bullets except the 270 Speer. It's a good deer bullet and would probably work, but a grizzly hunt is too important for probably.

JB or others,
If you couldn't get Big Game powder to use with the 286grain projectile, what would be your next favourite powder, assuming it hasn't changed from the data listed above.
Thanks

It's also hard to beat Varget--or as you know it in Oz, AR2208.

I couldn't squeeze you for an idea on what you would run 2208/varget at with a 286 grain partition or the like if possible? Should it be close on replicating the Big Game performance?

If anyone's interested, Real Guns.com has a reloading page for the 9.3 X 62mm. It covers most available bullets and appropriate powders, including RL-15 and Big Game. All data was taken from a Ruger Hawkeye African with 23" barrel. I was particularly struck with their results from RL-17, both in velocity and accuracy. It appeared slightly better than Big Game. So that intrigued me, and I bought some. At first it appeared to be a total flop--way too slow. My max load from RL-15 was giving 2463 fps with sub-moa from the 22.4" barrel of my Tikka. That's from a 286 Hornady. The suggested top load from Real Guns (their data) was giving 2500+ fps from RL-17 and MOA from the 286 NP. With the same load, I was just under 2400 with erratic velocity. But after further discussion with a friend and more calculations, I decided to give it another try knowing it's burning rate was supposedly close to IMR 4350. I went 4 grs over their suggested max and was still less than 2500 fps, but matched my RL-15 load in both velocity and accuracy. In fact, it shoots to the exact POI as the RL-15 load! But there appears to be less stress on the brass, from measurements and observation. So, I'm going to try 1 to 1.5 more grains that may give 2500 fps without undo stress. We'll see. Just thought I'd mention it. And, BTW, it was JB's article in HANDLOADER (referred to above) that sparked my interest in the 9.3 X 62. Thanks John. I am a fan of mediums as well as real Big Bores.

LowBC,
I would work up toward 57-58 grains of Varget as a maximum with 286's. It should come pretty close to Big Game.

CZ550,
Glad I could be a bad influence!
That's interesting about RL-17. I would have thought it a little too slow myself.

Thanks JB and others. I will let you know how my load development progresses.

All I can say is that MD's 9,3x62 data has worked pretty well for me...... The 250gr X bullets have shot so well in this and 2 other rifles I haven't bothered with other bullets yet..................dj
Remember this is all supposed to be for fun.......................

Any thoughts? I would agree - there is no way in the world the 9.3x62 is limited to 180 yards. Clearly with an AB with a BC of .5, and starting at 2600 fps it is good for a long way out. The references to it as a short range cartridge are due to its original intent in Africa, throwing very heavy bullets at very moderate velocities. As Mule Deer suggests, the 9.3x62 now makes a very good alternative to a 338 Win Mag loaded with heavier bullets. The 338 Win Mag only has a significant ballistic advantage out beyond 300yards, and are you really going the be using your rifle at those ranges? For most applications of the 9.3x62 and .338 Win Mag, i'd suggest not. The 9.3x62 is the more efficient cartridge at the ranges most of us actually hunt at. The .338 though remains a more versatile cartridge.

Mine, with the 250 Accubond @ 2600 fps and the Leupold CDS elevation turret is a 600 yd rifle. I've already proven it to myself.

Having had a 338/06, I am very inclined to go w/a 9.3 on my next mid bore, as I think it kicks things up a notch, not that a 33 won't work well, they do also.
I think you are set Alan. Elmer Keith used his 44 that far w/250s IIRC, at less than half that mv....no doubt you are slinging a chunk at a good clip. He would surely endorse a 9.3x62.

Any of you gents have info for the Accubond in a x74R you could share? Shooting in No.1 and SSK Encore barrel.
57 grains N135, 250 Accubond. 9.3X74R. A moderate load, that is a tack driver in my BBF97 Blaser.
There are no fleas on the 9.3s.

I should pick the rifle up in the next week or two so will have all the components ready to rock and roll when it arrives. I am loving all these 9.3 stories, it is building the excitement greatly particularly as our roar is only a coupleof months away :-)
