    Will reducing a shot charge increase pressure ?

    Assume a perfectly safe shotgun load double-checked in the reputable reloading manuals.

    Let's say the amount of shot in the published load is 1-1/8 ounce of shot.

    You reduce the shot charge to 1 ounce.

    No other change -- same powder and amount, same primer, same hull, same wad.

    Will reducing the shot charge from 1-1/8 ounce to 1 ounce increase pressure.

    The pressure will be higher only if the fine grained ball powder you are using detonates. HMB

    I know how it "ignites" but how does powder "detonate", pray tell?

    Pressure should be lower, partial ignition is possible resulting in squeakers and/or stuck wads and/or unburnt powder in your barrel. For a change of 1/8 oz it is definitely worth utilizing published data.
