Well the 300 WSM is a good cartrige,never heard of the gun.

The 300 WSM is a good cartige about the same as the 300 Win mag with 180 gr or less bullets.
The recoil is not as stiff as the 300 Win. IMHO.It is sutible for all NA game,they say they are not ment to hunt the Big bears due to some feeding problems due to the rebated rim.I have never had a failure,I've tried to jam it,but it's pretty hard to jam a bolt.

As for guns any of the one out today will server you just fine.
