This questions is along the same lines as the post about .17 Rem. question. I got slammed on another Forum for sugesting that the .270 was designed off the .30 Govt.(30-03) and not on the 30-06 case. overall case lengh for the .270 and .30 Govt. is 2.54" and the O6 is 2.494". so therefore winchester would have had to lenghen the neck of the 30-06 by .046". A 30-06 with a .046" longer neck is dmensionaly identical to the .30 Govt.
What say you??
