I've shot both the 300 winmag and 7 mm, I would describe the difference like this, the 150's feel about like a factory 180 or even a stout 165 gr bullet/load out of an 06. If you have no problem with the recoil of the 06 you shouldn't have a problem with either of the magnums. The 06 will do the same thing that the magnums can but just a around 200-300 fps slower.
