I make and market cast bullets, so far i have over 100 molds, by makers like, Lyman, Rcbs, Hoch, Paul Jones, Hensley and Gibbs, Saeco, NEI, Brooks, etc.Over 12 designs for the 45/70, I use 4 lubesizers(2-Lyman and 2-RCBS), over 40 dif. bullet sizing dies. Most of my guns are used for bullet testing which includes, bench rest shooting, penetration/exp. testing, as well as hunting, most of them have never seen a jacketed bullet.
