I'd like to use 2208 but currently don't have enough to run another calibre with it , should have more coming before long hopefully.
I'm using Lapua brass

I am using Graf's brass, which is PPU made. SO you could buy some factory from Gunworks, and it would be the same brass.

I can get 67 grains of 2209 in if I trickle it in, it comes up to halfway up the case neck. Bit more than that maybe. I am not afraid of standing on a load compression-wise, the only thing is if the bullet stays put overnight. (Some people think theres something "wrong" with heavily compressed loads, but often compressed loads will be more accurate. Sometimes anyway.)

I have tried two different bullets with the 2209 load, the Norma Oryx 285g and the Prvi PArtisan 286 grain. The difference between them is the PPU bullet is a proper round nose, so it has a bit shorter over all length compared to the Oryx which is more pointed.
Because the Hornady 286 grain is a proper spitzer, so will be a longer bullet, so you're doing more compressing than me, and I think I am loading them seated out more than you too.

I can seat round nose bullets out to 3.360 and still get them in the magazine of the rifle (Cant find the lands in this rifle, and still fit into the magazine.) With spitzer bullets like the 250 Accubond, I can seat them out to 3.380 and still feed - the sharper point doesn't hang up in the mag. I would expect your rifle will be the same?

Anyway, with the 286 g PPU bullet, I crushed the powder down and seat them to 3.360 all in one go, no need to be delicate about it, and the bullet stays where I put it. I measured it a few times at night and then in the morning and all good. I did the same thing and the Oryx bullets (which had a bit more compression remember because they are a little bit longer) they all grew overnight by .008 at least. I still shot them for a test, but will not use them with that load.

I have tried 2208 with 57.5g and a 286 grain bullet and also 60.5 grains with the 250 Accubond and it shot particularly well with the last, but I ran out of 2208 before I could chronograph anything, and have none left.

Out of interest, for extra brass I have run the experiment of turning .30/06 LC69 military into 9.3x62, loading it with AP70N and some Semolina and tissue paper to fire form them (have to shoot them straight up mind) Then I full length size the cases as normal.
They seem to be the same size internally as PPU (at least the 2209 load comes up to the same place in the neck) and the thickness of the brass at the case mouth is exactly the same as the Graf/PPU brass as well. (I thought it might get thicker. It does not.)
.30/06 military is supposedly thicker and less capacity than normal factory .30/06, so may be different if I used some of the commercial .30/06 brass I have here. I used the military because it doesnt say .30/06 on the headstamp, which I thought would be, well, better.) At least I know I can make 9.3x62 very easily if I want to.

I am turning in to a 9.3 junkie. Havn't had this much fun reloading a cartridge for ages.
