Hornady announced the 7mm A-tip, does that mean the 7PRC will be at SHOT?

[QUOTE="jpndave, post: 1857811, member: 5437"] I'd be interested to see how that data compares. Hornady does list some more extended information on this page. The lower speed, slower twist tracks pretty close with what you quoted. I don't know how they decided on the main page published data. Steve of Hammer bullets mentioned that they are seeing similar things with twist sensitivity and higher BC with their bullets spinning faster twists.
