I admit to being anal, but just to be fair I tried the dump method and went back to to my old ways. What I found was I can't cook as many bullets rolling around on mesh or whatever, also they are much more likely to roll together and bond unless I cook even fewer. If a full cure is used there will be marks on the bullets. If a partial cure is used (Less than what the powder manufacturer recommends) I don't even want to go there. Powder flows with gravity, so the bullet's base is not flat. I had marks on the bullets, instead of my usual smooth complete coverage, flat base bullets. When I hear just as accurate I have to ask, how was this proven? Sizing only makes the bullet's bands round, it does nothing to correct a lopsided bullet. It has been proven time and again any defect or angle to the base of a bullet affects accuracy.
However, the dump is a much faster process, but just OK instead as good as I can make it usually is in just about everything.
