RE: 243 wssm
There's always going to be popular rounds vs. best/better, it's a shame they're not one in the same.
I think the wssm's gave a lil extra fps....than their counterparts, i only though the .25wssm provided anything better.....
a .223 and .243 are already short cartridges, so not a big advance.....the .25wssm does give you a much shorter .25-06...
I would really like to see a 6mm/284 commercially loaded/chambered, maybe this one could stick....but as of not if you want a .243....i think the .243 win is the way to go....
