It sounds like your arguement against the mil is to play guessing games with the duplex??? Your system my be true, and I imagine can be accurate but it sure seems like it can leave allot of room for error. Agree'd you get what you pay for, and non front focal plane scopes require a set power for the mils to be accurate. Odds are I'd be using high magnification at those distances anyway... I also agree about the ranging aspect although I still believe it to be a usefull tool. Would you feel better if we discuss 400 yards where the drop is under 10" between the calibers we're discussing? I almost agree about the BDC's but they are becoming much more prevelent and are available in many of the popular calibers. IMO the 270 and 30-06 are all very similar in both power and trajectory up untill the 400 yard mark. I will give you this, the 270 is a slight bit better after the 400 mark but I think the 308 makes up for that with heavier available bullets. The .270 and '06 are best used with barrels of 24 or 26 inches, although this last isn't common. Were one down around 22" in barrel length, the .308 is probably the better choice for performance. In a bolt-action, and particularly for a handloader, the '06 is the best of the three for all around use. In a semi-auto critter, the .308 is better; practice ammo is cheap. The .270 is almost purely a hunting cartridge. In skilled hands it's quite suitable for elk.
