Well, as a reloader, I'd stay away from the 8mm variety. Part of the problem is bullet selection, the other part is bullet seating depth in a wsm case. You run out of capacity in the wsm long before the 338. If you shoot factory ammo, I think the wsm's are the way to go.

I'm a big fan of the 300 wsm, and thought about the 325, but decided against it.

Good luck in your decision.
