I won't get to shoot them until Wednesday, but I have a little 9.3x62 velocity ladder (2 rounds per charge) with 60, 61, and 62 grains RL-15.5 with the 250 NAB, and 58, 59, and 60 grains with an unknown 285 grain that appears identical to the Lapua Mega or PPU 285s. I have a ton of the 250 NABs I got for dirt cheap a couple years ago from SPS so I can afford to play with them for basic testing, but I am really short on the 286 Partitions so I plan to learn as much as I can with these cheap 285s before shifting to the $$$ bullets.
The loads above fit pretty well in once-fired Lapua 9.3x62 cases. The 62 gr / 250 NAB was a little compressed, but I can get just a little more under the 285. We will see, and I'll report back after firing.
Cheers,

If you use a 1 to 2 foot drop tube you will be amazed how much extra powder you can get in.
I use a 2 foot drop tube and can get 63gn of H4350 in my wheken with minimal compression. Without it 59gn of H4350 is very compressed. Might be worth a try if it gives you an extra 4 or 5 grains. A pia yes, worth it definitely.
