Eh? That's not even .45-70 ballistics, it would result in a trajectory more like this: https://en.wikipedia.org/wiki/.45-70#mediaviewer/File:.45-70vs.308.svg h

Eh? That's not even .45-70 ballistics, it would result in a trajectory more like this: https://en.wikipedia.org/wiki/.45-70#mediaviewer/File:.45-70vs.308.svg https://en.wikipedia.org/wiki/.45-70#mediaviewer/File:.45-70... And a much greater environmental effect on the bullet, probably precluding the accuracy promised. The 388TP is based on the .338 Lapua Magnum, I'd assume it's pushing 3,000 fps like the parent cartridge unless I hear otherwise. After spending some quality time with Google just now I couldn't find anything on the 338TP's velocity.
