All I have to say is that the 6.5x55 is an inefficient use of a .473" long action.
You must really think poorly of a .22 Hornet on a pre-64 Model 70 then...
Following your lines of thinking, much could be argued that the .260 Rem makes inefficient use of a .473 short action when you can tighten up the COAL and load a 6.5x284 or open the bolt face/feed rails and load a 6.5 WSM. I know you have touted the 6.5-06 on a long action because you get more powder per inch of action length, but even then, if more powder is the goal why not skip the -06 and load the .264 Mag or go all out and chamber a 6.5x375 Ruger?
Personally, I like the Swede in a LA and NOT being restricted to a specific COAL when loading 140gr or 160gr bullets--bullets that would otherwise eat a fair amount of powder space in a 2.8" mag box.
With that said, I no longer have my LA Swede and have gone the singe shot route ala Ruger #1. However, I disagree with the fundamentals of your arguement.
