My cz550 9.3x62.
Good story how I came about this rifle.
A gun show was in town close to my parents home. I went down for the weekend and my father and I went to the gun show Saturday afternoon and I seen this rifle on a table and was very interested in it. After my father and I return my mother hands me a $1000 for my wedding the fallowing month. So here im 5 miles away from a beautiful rifle with a $1000 more then I had when I was at the show.
When I left for home I made a quick stop back at the gun show and bought the rifle not telling no one besides my dad. I looked at it as a wedding gift to myself.

My hero!!!

I don't know if this has been discussed in this thread, but the measurements of the 9.3x62 match (very closely) P.O. Ackley measurements for an improved case except for the shoulder angle. .454" shoulder and base measurement which is greater on the 9.3 by a couple thousandths.
I measured the capacity of fired cases from a client's Sauer rifle with Norma ammo, as well as from my Oberndorf Mauser. The water capacity was 78gr. for each.
Factory 9.3x62 ammo is under loaded and inferior to modern standard .35 Whelen loads using modern powders, with it's capacity of 72 or 73gr. of water. That difference, as well as the larger bore size and case shape should have the 9.3x62 out distancing the "modern" .35 Whelen.
But then, John Taylor wrote that the increase from it's original ballistics of soft and solid 286gr. @ 2,175fps didn't need to boost to 2,340fps in the 1920's.
My 9.3x57 (57gr. capacity) did 2,170fps with a re-sized 300gr. Hornady and had only .0002" expansion at the web over a FL sized ctg.

You won’t regret it. I love mine!

Can any of the "custom" reloaders load a 60,000+ psi load, I dont have time right now to take up hand loading. My rifle is a ruger alaskan, obviously those pressures would be safe?

You guys are killing me!

Searching daily for a Rigby/Heym in 9.3

I would say anything up to a standard pressure of 65,000PSI is fine. That is the SAAMI standard for .270 Win. .338/06 and 6MM Rem. All those are tapered cases. The straighter the case, the less back or in other words, bolt pressure. Now, would a custom loader do that - maybe not. As with Ackley and Arch, case life is the final test on safe, usable loads. My 9.3x62 brass from the 1980's were converted to .375/06 IMP. and that was after running 285gr. Speers to 2,519fps and 270gr. Speer to 2,675fps. That Speer would be a bomb at those speeds. I also used that brass for 30 years, maybe 15 loads each one. It also is part of the brass supply for my new .375/06IMP. I've only had that one for 20 years.
CIP max (European law) is 57,000psi. AI says the SAAMI max. is 57,500PSI.
Standard .30/06 is 60,000psi, so is the .308 Win., .260 Rem. and a host of other ctgs.

Now, I should qualify that as there are a bunch of 9.3x62's on the Husqvarna model 94 action(96 in disguise). With those, 57,000 sounds resonable for max. loads.

 

[Mizzou100]

Understood, mine is a new Ruger alaskan, built like a tank

 

[Daryl S]

Yes, it is.

Steve at "Buffalo Bore" just did a video on their 9.3x62 ammo, etc. This outfit runs a 300gr. at about 2,380fps and 286's at 2,450fps and 250gr. at 2,650fps.

286 grain at 2400 FPS is sweet spot for my Rigby HS

What’s your load?

 

[Mizzou100]

250 grain is what the Buffalo Bore folks say performs the best and out penetrates the 286. My Ruger Alaskan delivers 1 inch groups at 200 yards with them!!

 

[Rare Breed]

What’s your load?

60 grains of Big Game powder

60 grains of Big Game powder

I am using the Buffalo Barnes loads from Buffalo Bore, most accurate rifle i have.

Congratulations! That weapon is so beautiful—isn't it a shame to drag it through the bush? In the rain, frost, and snow?

The easy answer is no it is not a shame to use a rifle it was purpose built for.
