So I picked up a single cav 452374 on fleabay few days ago and cast up a small pile the other night. Holy smokes is there a difference between lyman and lee! Actually Ideal, this is the old style from what I have read. Anyway, I have not found the sweet spot for continuous shiny boolits yet, so far I am content to make them frosty and crank them out. Also had the best reject-keeper ratio I've had yet! 7 rejects, 185 keepers. Very pleased with Ideal.
