Powder Measurement with a MEC
Quick question. I reloaded some 12 ga. target loads utilizing an Alliant powder published recipe with Red Dot. I cross referenced the MEC bushing chart on which bushing to use for the correct grains. I checked each of the first several shells utilizing a properly zeroed beam scale and each powder charge measured almost two grains lower than what it should have been. Do ya’ll find that you have to increase the size of your bushings to get a proper throw of powder? I had to increase the bushing size by three (30 - 33) to get close to the correct grains of powder thrown. Thanx
