All of my Lee molds drop heavy with anything but Linotype.
Lee
used to state that each mold was designed around an alloy "optimized" for that bullet design; but it's complete garbage, in my experience. And, they don't say anything about alloy, any more.
Every Lee mold I've dealt with (even 25+ year-old stuff), has dropped right on the money with Linotype and heavy with softer alloys.
I don't shoot straight Linotype, it's too brittle and a waste of good alloy.
I just cast with the alloy I want, and shoot whatever weight they drop at.
My 429-200-RF mold, for example, drops bullets at about 210 gr with isotope core alloy. I couldn't care less about the extra 10 grains. I worked up the load with 200 gr data, and stopped when I was happy.
