I am also a big fan of the 300 Wby. Mine is a custom rifle
I built several years ago; but it is the most accurate hunting weight rifle I have ever seen. This summer I took it to my range in Idaho and shot (over an open hay field with no wind flags) 2, 3 shot groups at 600, 1000 and 1212 yards. The groups measured 1.5 and 3.5 inches at 600, a little over 3 and 5 inches at 1000 and 1212 yards both. I also shot 1, 13 inch group at 1212 when I did not hold the rifle tight enough. 210 Bergers at 2980-3000 fps depending on the weather.
I also think the double raduis shoulder has more advantages than disadvantages.
Until the 300 RUM matches the success of the 300 WBY at 1000 yard matches the 300 Wby is the best 300 caliber magnum ever mas produced, and maybe the best ever period.
