They are for consistency of drop weight, intended to compensate for decreasing & varying amounts of powder in the hopper and work quite well. Minus a baffle, powders can even compress and tend to "bridge" the opening. Lee is the only manufacturer I know of that does'nt use a true baffle but has a workable alternative built into their hoppers. I personally can't imagine loading without one and on my Dillon, I even added a Uniquetek baffle. My powder drops with most every powder I use are very, very, consistent and repeatable. Some very precision-conscious reloaders use double baffles set at 90 degrees to each other.
