Thank you, Ray--I am out of luck. I plan on spray painting the RCBS mold nose cavities with stove (High Temperature) paint with a no. of coats to see if that works---maybe I will be lucky.I'm unhappy to report that I used to have a Saeco 4c in 070 back in my IHMSA days. When I retired from silhouette shooting I sold or traded off all my Saeco 4c 7mm moulds. I once had 070, 071,experimental 072, and 073. All were 4c! You might try placing a WTB ad on Cast Boolits for the 4c 070, as that's where mine all went.
