Re Deerslayers picture:
Actually, they don't look that bad at all.
Edges are sharp
Four future suggestions:
- Thoroughly scrub the cavities w/ toothbrush/liquid dishsoap
- Smoke the cavities with a wood match and preheat on pot ledge as it heats up
- Get a lead thermometer/cast at consistent 700-750, and
- Use a dipper (not bottom pour), sealed in hard contact with the sprue hole
