I had always been under the impression that the .270 Winchester, being Jack O'conner's favorite game cartridge for Western American game, would offer a considerable amount of aptitude over and above the .308 Winchester.<P>In reviewing the ballistics tables at Winchester's website, I find that the two chamberings do about the same thing with 150 grain bullets. Trajectories are quite similar. Downrange energy seems to favor the .270 by about 1 to 3 per cent.<P>What advantages might the .270 offer over the .308? I don't purport to say that there are none--I am certain that advantages for each cartridge exist. I imagine the .308 gets the nod in the accuracy department. What is the .270's claim to fame?<P>Wizard
