RCBS MOULD 40-300-SP-CSA 2-CAVITY (.410)

By Travis S. on Apr 05, 2023
Great communication from Grafs. Have had lots of pleasant experiences over the past 30 years.
I haven’t even gotten all the parts I need to build my 40-65 yet, but I have cast several pounds of bullets for it already. Cleaned the mold, pre heated on a hotplate while my lead was coming up to temp, then started casting. Within 10 bullets, it was dropping perfect bullets. Can’t wait to see how they shoot!
