Think all the WSSM are dying quickly, only one to make any sense was the .25 wssm I though, the 243 win and .223 are already short, so basically this gives you a 25-06 in a shorter cartrdige, though not really needed, none of these were needed, def get a .25-06, same ballistically anyway.

get a .270 WSM if you want something new/short/good. .270 wsm is said to be staying around, the .300 wsm certainly is here to stay.
