Who knows of a good source for one? I am using 9/16" wads under the Lee REAL 240 grain bullets and lubing them with deer tallow and BW 50/50. it is becoming a real PITA trying to punch out the durofelt with a hammer on a wood block.
Thought of buying a 9/16" hole saw and grinding it flat and sharping it from the inside out, But if there is a pre-made easy option and not very expensive I'll go with that.
