interesting bit of spam right there
Spam? Me? Well excuse me for trying to be helpful with info straight from the manufacturer which directly addresses OP's original question with real data instead of speculation. :P
Thank you for posting that email exchange and clarification on the velocity range direct from Hornady. A guy who shares good info like that is welcome here any time IMO.
Just ignore Mannlicher and other guys like that with nothing to contribute, I'm sorry that was your first experience with this forum.
