Here is a 338x300WSM that I found on gunbroker. Sounds like a need little package.

Interesting opinion about the 325 wsm and why it won out over the 338 version.

Was at the range today with my .338/.300WSM and shot three sub-one-inch groups with three different loads. I think the rifle (Rem 700 lefthand short-action) is ready for elk season.

What bullets do you use in yours?
