These seem to have contradicting theories behind them. I'm dealing with a large flake powder in small quantities (3-5 grains) for pistol and there's some powder bridging occasionally that I have to be vigilant for. I'd say once every 10-15 rounds I see a low powder charge. Which of these have you had success in preventing bridging in small powder quantities?
Powder is a little known "ETR7", burns like titegroup, looks like unique
Equipment is Lee Loadmaster progressive, auto disk (chain operated) case actuated
