Confused a little. There are two different published reloading's for a 45-70.. One recipe chart is preferred for used with the older 1873 Trap Door designs and clones of. The other published reloading is preferred for use in the newer 1886 Winchester & newer clones of including the Ruger #1
Of the two (2) published Loading charts. Which is considered the most accurate across its entire spectrum of reloadings? (1873 or 1886s.)
