The TenPoint Viper S400 is built around the Alpha-Nock / Alpha-Nock HP / HPX and a 20 in bolt, and its stated minimum is 410 gr total (Pro Elite 400) minimum. The Wicked Ridge Match 400 carries the same Alpha-Nock / Alpha-Nock HP / HPX, which is the first thing that has to match.
Its 20 in matches that bolt length, so it loads and shoots as the bow expects.
The Alpha-Nock is non-indexed, so orientation does not matter, but it must be an Alpha-Nock. An older Omni-Nock or flat nock in a narrow modern TenPoint can be caught above or below by the string.
