I downloaded one from IMR and it lists 66gr with a 175gr. @2910. That is so radically different it must be a misprint

I haven't been in the right place at the.right time to get retumbo or H1000 yet. Though a lot of people suggest them.

Imr don't meter well but seems to have a predictable temp sensitivity and fairly wide accuracy node.
