I'd get the .300 WSM over the 7mmWSM.

The reason is, I think the .30s are more versatile on a wider variety of game and just-plain kill stuff better. I also think the .30s are more inherently accurate, and less fussy to work with than 7mms. That's been my experience anyway.

Once I started using the .300 Win. Mag. in earnest more than a decade ago, I haven't revisted the 7mm Rem. Mag. I've had no practical reason to.

I'd look at these two WSM cartridges in pretty much the same way.........
