I’ve been back and forth between 30-06’s and 300WSM’s for years in multiple platforms. There isn’t a lick of difference in how they kill. I’ve come full circle to the 30-06 and find it easy to shoot as much as I like. I use less powder and since I’ve gone to a scope that allows me to shoot as far as I want, the MPBR zero advantage of the WSM is a non issue. They are both great calibers! Built up a scary accurate load with 155 Scenars at 3150 and it will be my mule deer/Elk load for the coming years.
