BY that yardstick all "hunting cartidges" are inherently accurate.
And do you really think that reloading cost or barrel life play a role? There are plenty of 30 cal magnums used in 1000yard benchrest for instance, but I don't know if I have ever seen a weatherby on a equipment list. Further, everyone I have ever dealt with has been pretty finicky and the accuracy has never been outstanding with any of them. Coincidence? Maybe..
