Accurate 1680 in a .32/20 WCF rifle

[velocette]

.32/20 chambered in a Whitney 2nd model rolling block rifle.
Looking for information on the use of Accurate 1680 in that rifle, using 100 ~ 120 grain cast lead bullets. Bore slugs at 0.3115", cast bullets are running .313 ~ .314"
Any ideas or suggestions?
