    well if you cannot find any hard data...find case of nearest capacity and start at low end of scale and cautiously work upwards......or take the data for weights you have got and keep working along the line....eg in cases like the .270winchester you get a straight line if draw up graph with powder charge on one side and projectile weight on the other...it will equate to SOMETHING LIKE 2 grns less powder for every 10grns more projectile.

    I assume you have read this. Retumbo, R26 and the slow vihtavouri powders are the go to it seems. What’s the rifle?
