Note comparison of CCI-300 (Large Pistol) and CCI-200 (Large Rifle) primers: despite generating essentially identical pressure, CCI-300 produces 8 fps more velocity. We see a similar result with RWS 5341 (Large Rifle) and CCI-250 (Large Rifle Magnum) – less pressure, more velocity. As in Table 1, CCI-350 (Large Pistol Magnum) generates Magnum Rifle Primer class results.
