Problem with going with WSM is none of the TRG M10 mags are setup for a short magnum. There are basically 3 mag sizes and all of them will all fit in the action.
One for .308 cal which allows for 74.5mm COAL
one for .300wm which allows for 89mm COAL
and one for .338lm which allows about 102mm COAL.

So ideally, I want to use something that would fit and feed from mags designed for those calibers and that I can fit within those dimensions if I want to mag feed.
The WSM might feed from the WM magazine but I don't really want to find out the hard way.

Technically I could easily run the Nosler cartridges or almost anything else up to a .338LM bolt face size, but I really want to balance performance with barrel life and the cost/availability of brass which is why most of the more exotic stuff is off the table.
I could gain a little with a fancier cartridge, but I think what ill end up with will be cost effective and still very capable. Especially with the long barrel.

Plan is to have it throated so a 180ELDM is close to the lands when seated to the 89mm that the 300WM M10 mag allows. That allows about an inch of the projectile to be sticking out in front of the case and still fit in the mag.
