I really like the caliber myself.  I like the larger bore diameter in a compact, short action package.  If you reload (which you should) you will NEVER have a shortage of brass as the parent case is the .308.  The recoil with a 225gr bullet is no more than a 30-06 with 180's IMHO.  I do not have a Ruger Frontier but I have handled one with a scout scope on it.  The gun I fired was a rebarrelled Savage 110.
