It's pretty easy to get 2500 fps with 286s in the 9,3x62 at "safe" pressures with several powders. I know this because have had such loads actually pressure-tested, and they were right around .30-06 pressures of 60,000 PSI--which are considerably lower than the 65,000 PSI SAAMI max pressure of a number of other cartridges.
And actual pressure-tested data beats pressure-guessing: anytime, whether with "pressure signs" or QuickLoad.

I bet your friend hasn’t experienced issues with a 9.3 w reloder 17 A 338wm for example will go from 64k to 93k with a small adjustment w R17 It is hard to get to 70k misloading and doing everything wrong in a 9.3 w R17 and 250acubond Take that with a grain of salt,
If you need or want all out velocity in a 9.3, this is the powder I have a 20” barrel, and want 2700fps w 250’s so that is why I use it, When I go to Africa I need 2510fps w 286 from a 20” barrel sends me to R17 I have a couple hundred rounds or more thru my CZ550 w R17 w no problems, It seems to work well w my set up and goals Some guys say they keep a dope chart for temp, some say they adjust 0.2g for temp, Some don’t like that, some won’t use the powder
I sighted it in for Elk today w 250’s pushed by r17. Off a bipod, w a rolled up sweatshirt at the butt, first group was 3” at 375yards, the ave of the 4 groups was 1moa, I got a little flinchy at the end or it would have been better
There are other powders that are very accurate and temp stable, but the velocity is just a little slower
I was told by a top gunmaker with a lot of actual handloading and regular almost daily shooting experience at the range that RL17 is temperature sensitive and has experienced issues. Don’t know myself, haven’t used it that extensively. Yes or no. Would like your comments please. Just trying to learn.
Not too sure about that. I have shot these loads between 17°c to 28°c and haven't noticed a difference.
I shot my A-Frame loads today. Turns out the A-Frame's basically have the same point of impact as the Hydros. The A-Frame's run a bit faster than the Hydros. Speeds where around 2540fps.

Thanks Mule Deer,
I have read that some of the users on the forum make use of your loads. I have settled on a load that is around 2539fps with a 286gr Swift A-Frame and 286gr Woodleigh Hydros at 2515fps. I did some brief penetration tests with the A-Frame and Hydro with wet newspapers. Interestingly the A-Frame expanded slightly more that a expanded .375 A-Frame.
There is a 9.3x62 shooting day close to Pretoria this weekend. I have prepared desent newspaper wetpacks and we will be putting my 9.3x62 going at 2539fps with 286gr A-Frame's up against a .375H&H shooting 300gr A-Frame's at 2530fps to see which penetrates the most. Should be interesting, I dont expect to see any clear winner though.
Talus I see 2625 with RL 15 and 250 gr bullets I use Nosler AB or Nosler B Tip With 286 Gr Bullets Nosler Partition I use Ram Shot Big game. 2520 FPS 22" barrel.
