Hi there,
I load 200 grain Nosler partitions to 2,350 fps, and they have worked very well for me for all my big game hunting. I've loaded them faster, but 2,350 is enough and easier on the action.
I have combination bbls in 9.3x74R and also double rifle sets for my Valmet. I also designed an "improved" 9.3x74R too. Of course the case holds more power, so that = higher velocity,
I use to swage a pretty good bonded core bullet in 9.3 out of type L copper tubeing, but quit that long ago. I sold a lot of them, and guys really liked them on big game.
As for slugs, as i remember, it's pretty good out to about 40 yards or so, but i never use slugs. I had choke tubes put in the shot bbls, so i can probable change chokes and get it tuned in with slugs if i tried...
Remington slugs go 1570 fps, while Winchesters go 1494 fps, so i always bought and carry Rem., if i carry any of them at all. I don't see in my notes how fast Breneke's go?

I do have some of them around, i should chronograph them :>)))
