Re: 30-06 vs 300 WSM vs 300 Win Mag look at these numbers
The 300 WIN MAG is the cartridge that most all other cartridges choose to be compared to. There is a reason for this. And I think most of us know the reasonl
Compared to the Winny, most other cartridges are what I like to refer to as "niche" cartridges. That is to say, they seem to perform best within, usually, a narrow window of improvement, if that can be found, over the 300 WM.
When cartridges are compared for their overall versatility, I don't see any that provide more of this than the 300 WIN MAG.
