Consider the 308 WCF and its ability to shoot 110 gr-200 gr loads for any big game hunting and predator dispatch. While the 358 WCF has its merits, it’s not near as versatile in long range work. A .35 cal 225 gr vs a .30 cal 200 gr, both at around 2,500 fps is for all intense purposes of equal authority. Granted the 358 has a 16% increase in frontal area, but the 308 will have much better bullet designs, much higher BC and greater Sectional Density. The 358 is a good one, however stamped brass and loaded ammunition are far and few between, the 308 however is available in every configuration and truth be told gives up nothing in the field to the 358, the same can’t be said for the 358 when going light or long distance and looking at the versatility for the 308.
