Don't get too carried away with the velocity with 235gn Speers!
The reason being that they come apart big time when driven fast and penetration is terrible!
I used these bullets over 20 years back in an early 602 Brno 375 mag for shooting pigs in outback Queensland and was never happy with them.

Had similar bullet break up and lack of penetration with 400gn Speers in 458 Win mag.
