I recently purchased a nice Lyman O-Mag press, which I believe is dated to around 1980. It has what seems to me to be an unusual linkage compared with my Lee Classic Turret, and it is somewhat perplexing.
With my Lee press, when I move the ram handle all the way down, the ram moves as far up as it can go (a full stroke). With the Lyman O-Mag, when I move the ram handle down, the ram moves up until about 95% through the stroke when it moves back down about a half of an inch vertically as the handle is completely down (a full stroke).
I took the ram linkage apart, and I don't see another way this ram can work, so I assume this is how it was designed. Am I correct in thinking that the only way I can use the press for precision tasks (e.g. bullet seating) is to screw a die down so far that the ram will contact the die before the full stroke is completed?
