That's too bad, Roth - the 270gr. Hornady was an excellent bullet, only overshadowed on elk by the 270g.Win. PP.

I note the measurements are almost identical to what a .375x57mm Ack.IMP would be.

In a Mauser action like a Mk. 10, that round would make about 2,300fps+ change with a 300gr. & 2,500fps with a 270 and quite easily I expect.
