Factory loads are generally milder pressure but even so the muzzle energy of the 6.5x55 Swedish is more than twice that of the 5.56x45 along with a better ballistic coefficient. If you hand load there are many options, see this article for starters.

But, "how far is too far"? Answer to that is, <762mm (<30") overall gun length.
