I was looking at shooting a .300 win mag. I now have access to a .300 wsm. I am not familiar with this caliber. The gun is a Winchester m70 for $450 out of the box with base and rings. Does this caliber shoot the same as the win mag but with less recoil? Does it have the same knock down power. The literature that I have read, says that it is very similar, but, I'd rather hear from the shooters though.
