If you want to try some cast and powder coated .223 i can give you a handful to load.
Just curious. What mould are you using for 223
I have been casting for my black powder (.451, .50, and .58) using roofing lead for years and have saved a fortune. I am now going into casting for lower velocity calibres using wheel weights (.38, 45 Auto/Colt, 45-70) to help reduce clean up time. As for the extra time it takes, I just think of it as part of my hobby and time away from the TV/PC.
