have long felt that the order should be .300WSM, .308 Norma mag, and then the .300 WBY mag. They all are pretty good with sub 200 grain bullets, but when you start talking 220 grain and bigger bullets the Weatherby moves up to another level. The .300 Ackley, .300 Jarrett, and even the Baer are all WBY mag clones in the end. Accuracey wise, the .300WSM is very good, but so are the Ackley, Jarrett, and WBY mags. Barrel wise the Weatherby and it's clones are by far the best. If the Ultra mag was a great round we'd see it in use at the 1000 yard meets. Instead it's the WSM, Ackley and the WBY mags
