I have owned a pile of bolt action rifles chambered for .300 WSM and i did notice that due to the 35 degree shoulder My Winchester mod 70 and Kimber Montana's fed these cartridges MUCH better than the push feed models like Remington 700's and Christensen Ridgelines...I dont own a .300 WSM at the moment as they are powder hawgs and powder has been mighty hard to come by these last few years....My 308's allow me a bunch more shooting out of a pound of powder 👍....Hb
