I have not heard of a MK VII (7) round in 175gr. Just 174.

The MK VIII (8) was in 175, really made for the Vickers MG, but again, both military rounds and anybody in their right mind would be loathe to use them on a nice double. And you're still an ass, but were still waiting for your answers,,,

A good principle to guide me through life: “This is all I have come to expect, standard lackluster performance. Trust nothing, believe no one and realize it will only get worse…”
