.68 is not 7mm, it is .270. The 7mm is larger then .270. The 6.5 is smaller then .270. Where does 7.03 come from???? I don't have a 7mm-08, but it is a fine cartridge. I prefer 7mm rem Mag and 6.5x55. .270 is redundant to what I have, and does not add any advantage. What have you been smokin'?I wonder? I would go with the .270 WCF for Western hunting. The larger 30-06 engine compared to the smaller .308 engine gives the old .270 an important edge.
And if you are turned on by metrics the .270 is after all a 7.03-06. caliber rifle.
