Congrats on the moose tag! I'm new to the 7 SAUM so can't offer advice there. I recently rebarreled a Kimber Classic 325 WSM with a Lilja 1:8 in 7 Saum. All I've shot so far is 180 Scenars with RE26 and it's been sub-MOA throughout load development. I would think any of the load combos discussed above would work fine. Good luck on your hunt...
