I have been casting since I was 15. Lots of my Molds are over 100 years old. I'm not going to beat a mold to death looking for perfection in my patterns. I cast for a standard of: (Will it work and give me shooting enjoyment?). Yesterday I got in a new to me mold an RCBS .38 cal., 140 WC. Its obsolete but there is data for it in the RCBS Cast Bullet Handbook and I'll have fun for many years with it. Cast up 500+ last night.
