I have shot a lot of whitetail and a few coyotes WI with a .243. That is a really nice cartridge for our deer; your 25-06 is probably a better one.
Take your pick on the .300 short vs the 30-06, thousands of lines of text written about that pros and cons. I don’t have much family left anymore, but if I had fond memories of my uncle, the 06 would get the nod.
The 300 short is between the 30-06 and the 300 WM but much closer to the 300. There really isn't a lot of difference between them. The only practical difference for hunting is in your head.
However, if you don't reload, ammo for the WSM is hard to get, here at least, and it's quite expensive. 30-06 ammo can be found about everywhere. As an example, right now MidwayUSA has a half dozen brands of 30-06 but only 1 brand of 300 WSM.
