That's why I listed what I used it in, I wondered if it would work on European actions or was more fit for the generic Remchestavages that many of Sinclair's customers are shooting, particularly high-grade M700 style actions. As for the muzzle down, yep, that's part of the deal, but I never thought it was a big problem. If I didn't own the Sinclair product I'd be adapting tresmon's method.
