    22-250 can't find any W-W but did find some Hornady in 22-250. Weight difference was 11 grs less for the Hornady than W-W . If I load same charge I wonder what difference there will be ? 36.5 grs of Varget behind 53gr V-Max 12" twist .

    The key to this revolves around the difference in capacity between the two brands of cases. Checking case volume in grains of water will tell you which way to adjust the powder charge to maintain the same velocity. I keep records of the internal case volume for each different headstamp, in each rifle that I have, to help me keep things straight.
