More about that. I use and load for it a 375 H&H since 1992. It was my main rifle for wild cattle, Big Red Deer and wild boar.
The standard loads I used with 300 gr bullets were 80/81 gr of any of the 4350, or the same charge of W760, for around 2550 f/s. These are also published loads.
So, 67/68 grs in the 9,3x62 is exactly in line with the relative case's volumetric capacities.
All of this would be only speculative if I hadn't checked in reality.

Best!

Some of the loads I am showing can be found in one of the most compleate load data for the 9,3x62, the GREAT BOOK: African Dangerous Game Cartridges, by Pierre van der Walt.
And in the Big Book of Gun Gack by John Barsness.

I agree, and I shoot my Husky and past 9.3x62s at 58 grs of RL-15 mostly and 60,000 PSI is IMO top max..

Most of my years in Africa I used a 9.3x62 with the original 27 inch Jefferys barrel and another with 26 inch barrel..Contrary to common belief I never had any trouble with them in the thick stuff, guess I just didn't know where the interfering branches were, or mayhaps I did!! Only as I aged and weakened did I go to 22 and 24 inch barrels..The long barrels work so much better off hand and still do as a matter of fact, at least for me, but weight and other age related proplems has barrel lenght played into the problem. I consider chopping brarrels on most of my guns from time to time, but usually back out.

One thing Im sure of the 9.3x62 with that 320 gr. woodleigh needs a 24 inch barrel and a 26 inch barrel is oh so much better.

There was a test in Sweden, sponsored by Sako, where they chopped barrels from new Tikka and Sako rifles, shooting Sako Hammerhead and Powerhead in 9,3x62.

They tested calibers,
6,5x55, 308, 30-06, 8x57, 9,3x62, 300WM

They tested factory length barrel, then 51cm and finally 45cm.

Factory ammunition Box said from 58cm barrel it should reach:
Powerhead 16,2gram: 730m/s
Hammerhead 18,5gram: 710m/s

Test rifle was a Sako 85 Bavarian rifle
Powerhead 16,2 gram reached 734 m/s in 45cm barrel.
Hammerhead 18.5 gram reached 709m/s in 51cm barrel

I agree, my hunting loads are 250 barnes with 60 grs of H414 (ww760) for 2650 and up t0 2700 plus some change, I shoot it at 2700.

286 Nosler and Accubond with 58 grs of 414 for near 2600.

56 grs of RL15 with the woodleigh 320 gr solid for 2380 fps (this in a 26" barrel on loan) This load surprisingly killed well on Texas whitetail does with shoulder shots, culling and got me 2377 in my 24" Husky..Hmmm!

So results wise we're darn close, I am going to jump on some of your RL-17 loads, and Im having good luck with CFE-223 amd BAlC (2) ...No big game avilable locally or anywhere else.

The long range ability of the 9.3x62 on my 400 and 500 yard range is pretty amazing with warm loads, the only weakness is me, and in a hunting situation it damn hard to do at estimated ranges, much different than on a known range target therefore my post wherein I call it and others 300 yard guns for the most part, and yes there is luck and exceptions...

A half inch group cannot be two flinches and a bullseye, it just does not work that way!

I've seen similar results with the 338WM and the 444 Marlin. There is so much total bore volume with the 338 and bigger cartridges, they seem to not be affected as much at the 17/204/223 class of cartridges that the reduction from 26" down to 18-22" does not affect the velocity as much as the smaller bores.

On a 338WM I took down from 26" to 22" I only lost twenty fps.
A 444Marlin cut down from 22" to 18.5" only lost ten fps.

Hey Gary, I forgot...I also had a Steyr Scout in 376 Steyr. That was a little brute of a carbine! As I said; hard to go wrong with a Steyr.

Thanks Patagonhunter, I will try and find some Big Game//I have been using CFE-223, its our latest and it sure is working well in the 9,3x62 and my 308 win, burn rate is very close to 748..other than that Ive been hunting with RL-15, 17 and H414 (760 same) No problems but hav not used the 9,3x62 in Idaho cold except with 4350 so far.

If I feel the need for a short tube it will be with my Win. 94 30-30 carbine, and its never failed me on deer or elk but I keep the range under 300 yards, mostly under 200 best I recall. Otherwise I shoot 22 inch fwts, or 24" for a std. Never been able to define the advantage of a carbine short of a saddle scabbard on my horses the short gun is much handier..
