I would go win mag, just based on ammo price.not 100%
sure but I believe the wsm and the win mag are pretty comparable ballisticly, with the wsm being a little bit
more efficiant. But the wsm is harder to reload for. and
I dont think the 200 fps dif between the win and wby is
going to make much difference unless your shooting at extremes.
Maybe someone with more knowledge will chime in.
hope this helps
