I'm having a rifle built this fall and have really been torn between the 7stw and the 300 wm. ballistically, it seems like you can make them almost identical - but there are clearly a lot more ammo choices for the 300wm. I will be using the rifle for 30% hunting (elk,deer,wolf) and 70% long range target. Give me your reasons why the 7stw would be your clear choice - given my purposes. Thanks in advance.
