The 300 rum isn't any more overbore than the 7stw is Muddy.
I've got hundreds of runds down my 300rum lh bdl and the bore looks new and shoots as well as when I got it. The 300rum is spendier to load but you can
load it down to 300win ballistics easily. You can't load up a 300win to 300rum levels. It is more of a can you take the recoil thing here but a good muzzle brake kills that problem. I like the 300win and shoot the heck out of it, but the rum is
a bit better performer than the 300win.
