did you warm up the mold first??? what temp are you pouring your lead at??? I warm the mold first by dipping the corner into the molten lead.... and I usually pour at 650 degrees
+1 clean your mold REALLY well...and crank up the heat! Preheat your mold as stated above. Pour those babies around 750* and see if they come out better. Good luck!
mentioned dippin the corner in the melt to warm mold , when ya do this keep lifting up on it a little & when the melt falls off & does`nt stik any more your ready to go.
