I've been using the loading data, such that it is, from the Hodgdon manual. The one I'm shooting now is:

Case: Norma
Primer: CCI LRM
Bullet: Sierra 200gr GK
Powder: Hodgdon 4831SC, 72gr

This is a max load in their book. So far, I've only put a few rounds through my rifle (pre-64 M70) with it but it looks to be an accurate load. I'm waiting for the weather to warm up a little to chronograph it.
