RE: 340 wby mag, too much recoil?
I would NOT be afraid to hunt and take any of the big bears with a 300 Win. Mag if it was loaded with 200 NP's. I tramped all over Alaska with one in my hands (includeing hunting brown bears) and never felt under gunned!
I've hunted with 338's and also the 340 Wby., and the 340 is expensive to shoot and does have a lot of recoil. Personally, i like the 338 Win. Mag better as it has plenty of power.
The 300 will have no problem getting the job done, if you do your part.
