My 300 WSM started life as a 6.5 SAUM then grew up. For me, the 6.5 was just not enough especially at extended ranges for large game like bull elk. I am sure some will disagree, but it's my experience.Got 6.5 saum and 264 win mag. I prefer 30 cal and 30 cal is just a little meaner
Do you see good accuracy and barrel life at that weight and speed?19" WSM 135PH 3505FPS absolutely devastating every hog it's met.
