Good question. I assume it's because of vastly superior metallurgy. I will confess to being mildly apprehensive about them being chambered in large-ish high pressure cartridges, but evidently it's unfounded. I have a Miroku-made Low Wall chambered for .223 and am delighted with it, by the way. But, the .223 case head area is a lot smaller than that of a .243 hence generates less push against the breech block.
