The 358W has about reached the end of it's life and I doubt that the 338F wiill even last as long . That , as I see it is the reality of it.
There seems to be more interest in smaller calibers. I used a 6.5x55 for 25 years as my deer rifle Now look at the number of 6.5 cartridges !! The 7mm-08 has become very popular as it should. Performance of all cartridges has improved with the many fine premium bullets and newer powders.
And Watson , bring your revolver !
