Reloading 7mm PRC Berger 195gr with LRT, N565, H1000 and Retumbo

This is the first video in a series on loading for a rifle chambered in 7mm PRC. This first video is centered around loading the Berger 195gr EOL bullet with LRT, N565, H1000 and Retumbo. Below is the workup and results for these loads - N565, H1000 and Retumbo were not fired for groups, they were for velocity and pressure data only. LRT was shot in (6) 3 shot groups and the results are below as well. All rounds were seated to CBTO of 2.629 (.035 off the lands) on a Hornady 7-28 comparator tool. All were loaded in Peterson brass with Federal GM215M primers.
