His daddy designed those cats. The co. name is Huntington, just in case the area code has changed.

If memory serves me right about 1959 or 60 Speer came out with a loading manual #3 dedicated to wildcats and me thinks both of those cartridges were in there also Warren Page's pooper and super pooper. I can't seem to find my copy. roger

looking for 243 rock chucker and 243 super rock chucker cartrage drawing.
Checked steves web site and did not turn up anything.

Find a copy of Ken Howell's "Designing and Forming Custom Cartridges", drawings are there I suspect. Scanner is down, sorry I can't put it here.

Oroville slipped into Area Code 530 after the quake.
