The 350 rem mag can be loaded down to 358 win levels, the reverse isn't possible.

I'm pretty happy with my ruger 350 rem mag, recoil is as much as I want in a reasonable weight rifle, and the accuracy is steller. With 225's @ 2700 fps its an honest 300 yd rifle.

Then again the 358 win with 225's @ 2500 fps and a 200 yd zero is an honest 250 yd gun.

Can't go wrong with either. As far as follow up shots, practice.
