I've had a year to play with this 300 wsm.
What I have discoveres is,
It is extremely accurate.
Shoots a variety of bullet well. Mine doesn't like the Hot Core in any weight.
With greater than 180gr the perfomance drops substantially. It will shoot the larger bullets but, with little or no improvement over the 30-06.
With 150 gr and 165 gr it stays up with the larger capacity 300 wm. 10% difference in powder charge.
With 180 gr it's an improvment over the 30-06 but, falls a little bit shy of the 300 wm
The felt recoil is the same as the felt recoil from the 30-06 or 308 win. Much more comfortable than the 300 wm.
I used it last year on my Elk hunts. It was easy to carry around thru the trees and brush we have up here in Washington. Sporting a 22" barrel the rifle is still very light and easily handled. I had the stock fitted to my pull and mounted a 2x7 32 scope on it. It comes right up, with authority.
My opinion only. The 300 wsm is one of the better developments in cartridges to date.
