I have shot 185, 190, and 210's out of my 300 wsm and they all shoot extremely well. All shoot a 3/8 in group or tighter out of my gun at 100 yards. the only reason I do not shoot the 210's now are the availability of them. I can get 190's or 185's easier where I live than I can get the 210's. after months of waiting for 210's I finally decided to make the change and the difference in performance in my opinion was little or none. hope this helps
