Ben,
I have seen that rifle before: super high quality build!
I think Ian hit the speed pretty darn close at 1400 fps
Ben was that a gas checked bullet?
I'm starting to think I would love a real 7x57. I have been putting in many hours with my Spanish 1916 ( now 7.5 x 57). The oversize throat makes it a frustrating challenge at times but I do enjoy loading for it
