    2 QL images. The first using AR2213 which myself and some of my shooting mates know, well in QL at least, is not the same as AR2213SC.
    Second image is Hodgdon H4831 which is AR2213SC.

    Pretty basic analysis with more accurate results if measuring COAL and water capacity of a fired case.
    QL can be brilliant or off the mark for some powders. Quite often you need to reverse engine QL to get relevant results ie fire a load, then adjust QL to match real world velocity.

    So, what I have posted may not be gospel and other QL users may pick up something I have done wrong.

    The pMax in QL is the max pressure rating of the cartridge case, not the action being fired. QL obviously has no idea of the strength of the action being used.

    Did you have any velocities for your first shots fired?
