Tough question - .358 is a weak diameter bullet-wise but I'd rather have the medium bore, especially if a grizzly is on the agenda. Hence why I built a .375 WSM that will likely be used for all elk applications going forward. If I had to choose I'd take the .358 I think and try the 250gr Partition or Weldcore. The A-Frame's BC is a little hard to stomach but an option too. I use it in my .375.
