You might want to try some different primers and play around with the COL. As for the cases, have you trimmed. Also suare up the primer pockets.
I have never known of a M700 that wouldn't shoot under 1 inch with the right load. The factory trigger set is terrible but can easily be adjusted to the 2-3 pound range which is where a hunting rifle should be.
Keep at it, your effort up front will be well worth the reward when you find the right load.
