Kudos for pointing that out! That's why the bullet matters. Linotype vs. Alloy #2 vs. Swaged/Soft lead behave completely differently when they hit the forcing cone and rifling. Lyman #2 Alloy is 5% tin, 5% antimony, and 90% lead (15 BHN) . Linotype is generally 4% tin, 12% antimony, and 84% lead (20 to 22 BHN). All components matter.
