Yes, I agree that for what ever reason bullet manufacturers tend to make bullets in .264 and .284 diamaters more aerodynamic than any other bullet diameters. I don't know why they do this but they do.
I will stand by my post saying that if the 7mm guys got the .280 when we already had the .270 then the .270 guys should get the 270-08 when we already have the 7mm-08.
I won't post on this again, as I doubt anything will be resolved from it anyway.
Look at it this way. All of those people out there that didn't know anythingabout SD, BC, ogives, bullet diameter, boat tails, etc... etc... learned something with all of us "arguing" about all of this stuff.
It's all for fun any way.
