Kachok said:?!?!? NO WAY! A 185gr VLD has .549BC and that will even work in the slow 1:12" twist on a 308, step up to a standard 1:10" and you can use bullets well into the .700s what .243 cal bullet are you talking about? Even the ultra long 115gr VLD only has a .545 and it NEEDS a custom 1:7 twist barrel. Some people have gotten the 105 A-Max to work out of the harder to find 1:9" twist but that one falls well shy of the 30 cals with a .500 BC
How fast are you pushing that 185gr VLD in your 308 Win? A BC of .549 means very little as do the ones into the .700's with 308 Win velocities.
Kachok said:My regular ol hunting bullets in 6.5 have better external ballistics then even a 105 A-Max so does my 180gr soft point Game Kings for my 06, that was the point I was trying to make.
I actually own and shoot a 6mmx284, a few .243's, several 308 Win's, a 6.5x55, a 260 Rem, a 6.5x284 and a 6.5 Gibbs which is a 6.5-06 maximumly improved so I have a little hands on experience with the what we are talking about.
Looking up ballistics is ok and believe they are a good start but only use them as guidelines. Will get an idea of what cartridge/load will do by looking at a chart but that's its. I chrongraph my handloads and certainly dont use velocites a loading manuals states. There are lots and lots of variables that affect ballistics. Have actually set up my chronograph up out to 700 yards and shot through it to get real velocity numbers. There are no shortcuts, you have to go out and actually shoot what ever distance you choose to get truly accurate results with your firearm, your ammo, your conditions etc.
Please list the regular hunting bullets you use in 6.5 as I would be interested in punching some numbers together to see for myself. Without even looking, I am thinking the 180gr Sierra GK falls short of the 105 Amax trajectory, it's really no different than the 308 Win.

Back in the late 80's early 90's I used the new back then Barnes X bullet. The 75gr flat base .243" cal was a laser hammer when shot at just above 3800fps through my 6mmx284. That thing would flat lay deer and coyotes out, to bad the discontined them years ago when they brought ot the banded X bullets.
