Barnes data lists 250gr TSX: https://barnesbullets.com/content/barnes-loaddata/rifle/366/9-3x62mmWeb.pdf
Data might be adaptable for 250gr TTSX it's a rather long projectile for my rifle takes up significant case capacity prefer 250gr TSX.

CFE223 is what I load 250 grain accubonds with and I get 2600+ fps. I think it would be viable with the TTSX, but you would have to work up a load right from scratch. With the longer bullet, etc., a ball powder is nice.
A friend speculates that the 250gr 9.3 projectiles should be designed to expand less with the higher velocities. His observations with Laupa however.
Anyone loading 9.3x62 for in a semi auto?
Yep. I have used S&B magnum primers the entire time with my load development. No pressure signs. I am using a CZ550 Lux with 23.8" barrel.
Velocity depends on distance. Will you shoot an animal at 50 yds, or 250 yds? Will your bullet work at both or do you need to think about it before you pull the trigger?
Just saying there are many variables and muzzle velocity is not the final consideration.
Not TTSX but ECX 250gn, I get 2570fps in a 24” barrel cz550 using 61gn of Varget and CCI LRMP. The bullets are seated at 0.052” from jam. The rifle/brass shows no signs of pressure(might be different in your rifle), at 61.5 and 62 the primer started to get flatish, but still bolt lift and extraction was smooth and easy.
And it is accurate.
