I made my own already.The ones I was finding ran about .245.Minimum material condition!

I used mold core pins.They are H-13 and come in two different hardnesses,one is in the low to mid 40's on the "C" scale.They are through hard and a few 10ths over nominal.

I would not try mold ejector pins,they are usuallt .0004 to .0007 under nominal,but they are nitrided harder than a woodpecker's lips!!They do not machine well
