That being said...any reason to go with a 150 vs 165 vs 180 grains?
I have not tried the 180 Super X (White box) Just the Supremes with the Nosler ballistic silver tip
In the black box. It is Winchesters premium ammo and has performed well on game as well as accuracy.
I have not had good luck with the Super X ammo ether. I think it is there bullet selection.
The reason I recommend the 150 is velocity, performance and recoil. there is no need for higher BCs at 5 to 600 yard shots. So why pay for the high end bullets and ammo when its not needed. also the poster does not reload so some of these bullets are not available to him.
One other thing most of the factory barrels are poor at best and are lightly contoured and it has been my experience that most Light barrels preform best with light bullets.(Less harmonic problems).
Nothing wrong with using heaver bullets I just think they are needed for what he wants to do and pay for.
I used 165s and 168s for 600 and 100 yard matches in a 308, So I know they will work in the WSMs
Just my opinion
