My answer to "WHY?" would be that in a number of cases/instances, the power of the '06 is not necessary and is actually "overkill". This versatile cartridge can be loaded to get the job done, without blowing up meat, or one's shoulder, or without traveling to the next county, after exiting the deer. There are plenty of places/terrain, where the 30-30 Youth Load, with a 125 grain FNHP would be most adequate for the harvest.
