Welcome.
Either twist is fine. The 1:9.5 will net a bit more velocity. The 1:8 will stabilize the heaviest you can go. Maybe look to an 1:8.5 or 1:9 instead, as those are closer margin and probably a better option for the widest spread of bullet weights. But hey, I use a 1:7.5 with .264” bullets, so what do I know? LOL!
