Hi....quick reload question...trying to work out appropriate MEC bushing size / rule of thumb guide when converting a Red Dot recommendation to a Promo load. I realise that Promo is denser & so should use a lower bushing number...is peoples experience to go 1 bushing size lower or 2?
For example if the RED Dot / promo powder requirement is 18.5 grains, MEC's recommended bushing size for red dot is #31...where would you start at for 18.5 grains of Promo ...#30 or #29? I realise I will need to measure etc, but am looking for general guidance so I can at least start in the right ball park.
Thanks for your help.
