Agree, but Woodleigh FMJ .577 750gr SD=.313
whereas Woodleigh FMJ .600 900gr SD=.334
So which should penetrate further...?

Easy to answer. Simple physics, at the same velocity, equal construction, the heavier SD will always penetrate more. So the .600.

The above difference in SD is not great however.

Bullet shape may have some influence: spitzer; pointed; semi pointed; round nose; flat point. Many argue variously over this, alleged "scientific" bubble arguments, alleged test results etc etc.

Showing a single test result from a non independent tester on a website is just advertising and PR.

Testing and proof is determined from independent sources and a significant number of equivalent tests.

Irrespective of this the higher SD in theory will penetrate more.
