I think that's the best of the WSM's and it's all but gone from any production rifle chambering line-up. Tough to find brass for them too.
Agreed, too bad they came out a little later than the .270 & .300 WSM's. The slow start along with Winchester's plant closing and quality control (feeding from magazines) which gave all of the short fats a bad rap.
I'm thinking the arms mfg. industry wants it to die because they would lose so much money from sales of calibers that it would hurt.
