I was looking at a LEE mold I purchase new, and have been using for a couple months now, and noticed that the sprue plate does not sit up tight against the mold for the front cavity. You can actually see daylight between the plate an block from the side. The rear cavity is tight. I don't know if its the sprue plate that is warped, or if the mold block itself is not flush????
SOOO, I decided to run a little test on the mold to see if there is a difference in weight from the front cavity to the rear? Sure enough, the front cavity consistently drops a bullet 2 grains heavier than the rear cavity!!! This is probably the reason I'm getting inconsistent groups. PLUS, the rear cavity drops a more consistent weight bullet (0.7 grs difference) when compared to the front cavity (1.2 grs difference). I'm going to only use the rear cavity on this mold and use it as a single instead of a double.
