Out of my 30-06 I would have to set the jugs up short of 400 yards to get velocities in the 2200 fps range. I'll need to reload a few reduced load rounds to simplify the process.
Your GMX testing at 100 yards, was that out of 30-06 factory round? If so, that bullet would still be around 2730 fps (Superperformance) or 2597 fps (Full Boar).
Nope, that was out of a 20" .308 carbine. MV chronographed at 2540. Federal Factory 165 gr. Barnes TSX data inbound within the next week or so.
