Terminal Velocity Range Hornady GMX Heavy Bullets

[Flouncer]

I e-mailed Hornady this AM. Anxious I guess. Does anyone here have accurate information on the minimum velocity range recommended for the Hornady GMX bullet ? 8mm/.323 180g taken one step further. For example, Lapua publishes 490m/sec or 1650 fps for Naturalis Bullets, the Speer tech I had three e-mails with just gave me the run around. - Thanks

Received Tech Mail from Hornady - 1900 fps in case anyone searches this. Using Lapua Factory Ammo for their 180g Naturalis loaded ammo as a baseline for a GMX velocity reload, this makes the Hornady bullet in 8x57 at 2690 fps a 400 yard cartridge. About an 8-inch high/low tunnel to shoot through with 1,500+ ft/lbs terminal energy.
