I'm not buying that the wsm will outperform the 300 winny, its just not possible. the win mag has alot more capacity, so you could get more from the larger case. cubic inches always makes the most horsepower.
But ammo manufacturers are bad about hypeing stuff, in 1997 remington legitimized the 7mm stw, rated at 3430 fps with a 140, in 1998 or 99 they brought out the 7mm RUM, the new catalog showed the STW rated at 3300 and the RUM at 3470. My personal 7mm STW runs a 140 at 3550 fps.
If you can load up the wsm and the winny to max loads in a model 70 action, the larger case will burn more powder and achieve more velocity
