You can always count on anyone advocating for the .30-06 to have all sorts of misinformation. You're no exception.
.308 AI shooting the 200gr Terminal Ascent. The top temp-insensitive powder is H4350 and velocity out of a 22" is right about 2600 at max load. It doesn't hit 2100 ft/s until 450 yards at elk elevation, and that's with a 200gr not some piddly 165. Not that it matters much, since the bullet is designed to work all the way down to 1350 ft/s.
You simply don't know what you're talking about.
LB, what is the case capacity of your 308 WCF AI in H2O? Also, how many grains of H4350 are you applying as Max Load?
