For flexible usage, we provide our reloading data in metric and imperial dimension systems, i.e. charge weight in grams and grains as well as muzzle velocity in meters and feet per second. All the loads on these pages are pressure tested according to the C.I.P. method. The listed maximum loads should never be exceeded.
We wish you successful reloading with Vihtavuori premium rifle powders!
