You did not get a 400 Gr bullet in the 45-70, to go 2270 fps, you didn't have your chrono out far enough, it sounds like. But, you didn't get that sucker going 2270 fps.
With buffalo bore only pushing their 405 @ 2000 it does seem like a stretch. BUT Eldeguello knows his stuff. The ruger No. 1 is an extremely strong action. To say he didn't do it is kinda arrogant, and very rude. Why not just ask him how he did it instead?
