If it were me I would consider a 325 WSM or to get a better bullet selection, neck it up
The 300/338 is popular but you have to neck up .030 and you gain nothing in case capacity.
The 7mm WSM has a little more case capacity because of the shoulder being further forward
but necking would be very difficult and the necks would be very thin when finished sizing.
The WSM is about the most powerful cartrige in a short action and nothing has to be done
to it (Body has very little taper and the shoulder is already 35o (37 to 40 is about max).
Factory brass is available and if you decide on a 325 factory ammo is available and the bullet
selection has improved in the past few years with weights from 150 to 250 grains. there is a
200 grain Accubond that is ideal for long range hunting/shooting .
If you single load the WSMs you can seat the bullets out, giving you a little more case capacity.
