Welllll...The larger expander wasn't the "end all, be all" answer to curing leading just past the forcing cone with soft swaged bullets. But the offender today hasn't had but the three factory proof rounds through it since it was new back in the mid 1980s until this last autumn when I "ruin't" it for collectors by shooting it. Otherwise the larger expander seems a vast improvement over the smaller "as supplied" units. The new four cavity mould's recovered range lead bullets performed better than any of the store bought stuff, even though the lightest bullets were used.
Additionally, the storm yesterday uncovered lots of bullets for recycling! Cheap muddy fun we had picking "lead berries" from the berm. Possibly 60 lbs altogether in a fairly brief session.
One new woe: probably had the sprue plate screw a bit tight on one mould set. Fairly well galled in the area immediately surrounding the screw. Plate might be somewhat warped as well, but I think it's mostly the pivot area wear that's keeping the plate from sitting flat on the mould top.
A couple of photos from last weekend's casting session (Too busy shooting today to do range photos, so it must have been a good morning even though it was questionable at the start!):
