The following mold makers have certainly provided me with quality products or i would not recommend them: NOE, BRP, CBE(Australia),LBT, Accurate Molds, Mountain Molds, Paul Jones, M&P Molds(Slovenia), Leeth. Most of these are US manufacture......The following make production molds and usually are a good mold and can be bought off the shelf from Buffalo Arms, Midsouth Shooters, Grafs, etc.....Lyman, RCBS, and Saeco..of these(production) I would rank Saeco the best.......In addition there are some discountinued makers that were top notch and if you find a used one in good shape grab it.....Hensley and Gibbs, Don Egan...........Ben
