.45-70 mould recommendation?

[rdnck]

The saeco 645 is very accurate in my Shiloh 45-70, and it is a proven 1000 yard bullet. However, it is the only bullet that has ever leaded the barrel in that rifle, and it leads every time I use it. The old standby tried and true 457132 Lyman Postell out of a Lyman mold works and works well out of any rifle I have tried it in, and shoots for me with any barrel twist from 1-18 to 1-22. It is definitely worth a look. Shoot straight, rdnck.
