I've had them both and to answer your questions:
1) Yes, Recoil is much stronger in the 300WSM but, it is a much lighter Short Action Rifle which is the main reason for this.
2)In Theory, the better efficiency and lower SD of the 300WSM allows for better accuracy but, we all know that accuracy has too many variables for one cart. to have an Appreciable advantage over another. In my case, the 300 WSM
is more accurate but, that has nothing to do w/ the what cart. it is.
3)Can't help ya too much on this one. I haven't put enough rounds through the 300 WSM to know if there will be a difference but, I strongly believe that there will be very little if any difference in Barrel life between the two mentioned carts.
If every variable was the same between two custom rifles
the 300WSM would probably be a better choice w/ bullets of 180 grains and less.
