Got some time at the range Saturday.
Same gun, brass, COL, primer as above.

Just for fun, and to get a HEAVIER Bullet:
357 Magnum Lead Semi Wadcutter 158 grain
Seated to 1.240" because the design of the bullet required it for my barrel
158 PBSWC:

10.0 1195 1234 39 1212 19

I need to revisit 800X and 147 grain bullets. I shot some 147 Gold Dots at 11.0 of 800X. I got good velocities (1449 Average), but the head expansions were more than any of the above loadings.
I have also backed down on my 115 FMJ & AA#2I from 9.0 to 8.8 because 10 rounds of 9.0 yielded one round slightly greater head expansion than I want. (9.0 = 1453 FPS average)
Stay Safe!
