The other side of all of this is that FAR less accuracy than most handloaders think is necessary will consistently take big game out to 400 or even 500 yards. For some reason, we've become convinced that a load that shoots 3/4" 3-shot groups at 100 yards is vastly superior to one that shoots, say, 1-1/4 inch groups.

Even a pronghorn has a vital area about the size of a volleyball, and most big game animals are larger. Believe me, if you can shoot reasonably well, a rifle that shoots 1-1/4 inch 3-shot groups at 100 will hit a volleyball every time at 400 yards--if the shooter knows what they're doing. At "normal" ranges that's the real factor, not what are actually small differences in group size.
