RE: 243 WSSM ???
The cartridge is already dead! isn't it the same as the .243 win just shorter? the only one that did anything IMO was the .25wssm which gave you a .25-06 in a shorter action, the .223 and .243 are already plenty short, so a .223wssm and .243wssm really didnt to much for us. all 3 rounds are dead.....
